Description

Automatically adjusting equipment and automatically adjusting correction method

The Japanese patent application No.2011-242251 that the application proposed based on November 4th, 2011,And advocate its priority, quote its full content here.

Technical field

The present invention relates to automatic adjusting equipment and automatic adjusting correction method.

Background technology

In pianotron or the such electronic musical instrument that possesses keyboard of electric organ, general main with rightHand bullet melody, with the accompaniment of left hand bullet, or presses and gives as security the multiple keys that form chord. Thereby, suchIn electronic musical instrument, need to be used for the right hand and left hand respectively according to the exercise of the self-movements such as music score.

Which kind of like this, no matter, in the method for playing of piano and the method for playing of organ, all need the right hand and a left sideHand, simultaneously with different gestalt movements, needs corresponding exercise for this reason. Particularly, although can bePerformance melody and the motion right hand is felt difficult player but carry out different performances with left hand simultaneouslyMore in beginner especially. Thereby, require to have by player and play melody, can oneself with the right handMake should be by playing the electronic musical instrument of the accompaniment tone generating movingly with left hand.

For example, in No. 3099436 communique of Japanese Patent, proposed with lower device: by melodyNote data is stored according to multiple intervals, in the time giving the chord name in the 2nd interval of note data,With reference to adjusting data, with the note data in the 2nd interval corresponding note data, the 1st interval and right beforeThe chord name that give in the 2nd interval, determines new chord name.

As being used for one of key element determining like this chord, use the note that forms melody, but these soundsSymbol is not to be reflected in equably respectively chord to determine. For example note is according to being included in which batAnd they are strong and weak different, in addition, the temporal position in clapping according to it, power is also different. Thereby,Wish that its power of reflection decides chord name. In addition, more wish be not only with reference to single note andDecide chord name according to the transformation of multiple notes.

So in TOHKEMY 2011-158855 communique, having proposed can be based on forming melodyNote strong and weak and change the automatic accompanying apparatus that determines in real time and suitably chord name.

But, if carry out in real time chord setting, become and utilize rule of thumb rule to make on one sideDatabase determined in a way on one side, even can enter accurately in simple melodyThe real-time chord setting of row, but in the situation that using grace or using chord, have real-time chord settingThe situation of precision step-down.

One of reason of the precision step-down arranging as this chord, can enumerate needs in the time that chord arrangesThe precision of tune (tune) judgement of melody lower.

The tune of melody is not always certain. According to the difference of melody, change halfway other intoThe situation of the modulation of adjusting is a lot. In the situation that having there is modulation, need to be at the chord that determines to giveBefore name, which tune judgement has been converted to and has obtained new tune.

Conventionally,, in order to judge the tune of melody, use the resume of the pitch of the melody that forms this melody to carry outThe situation of judgement is more. But, if want the melody judgement according to the melody of playing in real time to adjust,In the time of the beginning of melody phrase etc., be included in pitch in resume less, according to the classification of melodyAnd existence is difficult to the situation that correctly judges and adjust.

Like this, the precision arranging in order to improve real-time chord, need to make the tune of real-time judge more accurate.

Summary of the invention

The object of the invention is the essence of the tune judged result of the melody of playing in real time by further raisingDegree, improves the precision of the chord that melody is given in real time.

In order to achieve the above object, the automatic adjusting equipment of a technical scheme of the present invention, has:Play input mechanism, the Qu Xuanlv of performance is inputted successively; Adjust in real time decision mechanism, based on defeated successivelyThe resume of the pitch of the Qu Xuanlv entering, judge tune in real time for this Qu Xuanlv; And non real-time adjustingPositive mechanism, after the Qu Xuanlv of above-mentioned performance input mechanism performance finishes, revises in non real-time by above-mentionedThe tune of adjusting decision mechanism to judge in real time; Above-mentioned non real-time tune correction mechanism has: determine adjusting data storehouse,Relation between the final pitch of expression Qu Xuanlv and this final pitch and tune; And non real-time tune is sentencedBreaking mechanism, judge according to above-mentioned final pitch and from this determine the tune that reads in adjusting data storehouse whether with byState the tune coupling that real-time tune decision mechanism is judged, the in the situation that of coupling, this tune of judging is doneAdjust for determining.

Detailed description of the invention

Below, with reference to accompanying drawing, embodiments of the present invention are described. Fig. 1 represents to have adoptedClose the figure of the outward appearance of the electronic musical instrument of the automatic adjusting equipment of present embodiment. As shown in Figure 1, haveThe electronic musical instrument 10 that closes present embodiment has keyboard 11. In addition, on the top of keyboard 11, have,Be used for carrying out the switch of appointment, the appointment that starts end, rhythm pattern of automatic accompaniment etc. of tone color(with reference to label 12,13); Be used for starting non real-time chord correction after real-time chord arranges endNon real-time chord arrange revise switch 14; For example, with the various information, that show about the melody of playingThe display part 15 of tone color, rhythm pattern, chord name etc. About the electronic musical instrument 10 of present embodimentFor example there are 61 keys (C2～C7). In addition, electronic musical instrument 10 can carry out automatic accompaniment to openIn these two performance patterns of the automatic accompaniment pattern opening and the normal mode that automatic accompaniment is closedPerformance under any.

Fig. 2 is the piece figure representing about the structure of the automatic adjusting equipment of embodiments of the present invention.As shown in Figure 2, about the automatic adjusting equipment 10 of present embodiment possess CPU21, ROM22,RAM23, audio system 24, switch group 25, keyboard 11 and display part 15.

CPU21 carries out the control of electronic musical instrument 10 entirety, the pressing of key of keyboard 11 given as security and formation switchThe detection of the operation of group's switch of 25 (for example, with reference to Fig. 1 label 12,13,14), according to keyAnd the control of the operation of switch and the audio system 24 that carries out, according to being entered by the pitch of the musical sound of buttonThe performance of the decision of the chord name of row, the automatic accompaniment carrying out according to automatic accompaniment pattern and chord nameEtc. various processing.

The various processing that ROM22 storage is carried out CPU21, for example, the operation of switch, keyboardCertain key press signature, corresponding to the pronunciation of the musical sound of button, according to being entered by the pitch of the musical sound of buttonThe performance of the decision of the chord name of row, the automatic accompaniment carrying out according to automatic accompaniment pattern and chord nameDeng program. In addition, ROM22 has and preserves for generating piano, guitar, bass drum, little armyThe Wave data district of the Wave data of the musical sound of drum, cymbals etc. and preserve represent various automatic accompanimentsThe automatic accompaniment pattern district of the data (automatic accompaniment data) of pattern. RAM23 storage is from ROM22The program reading and the data that produce in the process of processing. In addition, in the present embodiment, fromMoving accompaniment pattern has the chord pattern of the formation sound that comprises each chord name, the basis that comprises rootPattern and the rhythm pattern that comprises tympanitic note. For example, the note of the data of chord pattern and basic patternPitch, pronunciation timing (pronunciation moment), the duration of a sound that record comprises musical sound. In addition the data of rhythm pattern,The tone color, the pronunciation timing that comprise musical sound.

Audio system 24 has sound source part 26, voicefrequency circuit 27 and loudspeaker 28. Sound source part 26 examplesAs received from CPU21 about by the information of the key of button or about the information of automatic accompaniment patternTime, read the Wave data of regulation from the Wave data district of ROM22, generate the pleasure of the pitch of regulationSound data output. In addition, sound source part 26 also can be by Wave data, particularly snare drum, bassThe Wave data former state of the idiophonic tone colors such as drum, cymbals is exported as tone data. Voicefrequency circuit 27Tone data is carried out to D/A conversion amplification. Thus, export audible signal from loudspeaker 28.

About the electronic musical instrument 10 of present embodiment is under normal mode, the pressing of the key based on keyboard 11Give as security and generation musical sound. On the other hand, electronic musical instrument 10 is grasped by automatic accompaniment switch (not shown)Do and become automatic accompaniment pattern. Under automatic accompaniment pattern, by the signature of pressing of key, produce this keyThe musical sound of pitch. In addition, based on being determined chord name by the pitch of the key of button, produce according to comprising this,The chord constituting tone of chord name is at the musical sound of interior automatic accompaniment pattern. Below, electronic musical instrument 10 is existedThe situation of moving under automatic accompaniment pattern describes.

Below, illustrate in greater detail the processing of carrying out in the electronic musical instrument 10 about present embodiment.Fig. 3 is the example of the main flow carried out in the automatic adjusting equipment being illustrated in about present embodimentFlow chart. In addition, although do not illustrate, in the execution of main flow, also with between official hourThe timer that the Counter Value of interrupt counter is increased progressively every execution increases progressively processing.

As shown in Figure 3, if the CPU21 of electronic musical instrument 10 is put into power supply, carries out and compriseThe removing of the image of the data in RAM23 and display part 15 is in interior initial treatment (initialization placeReason) (step S1). If initial treatment (step S1) finishes, carry out switch process, this switchProcessing is that CPU21 detects the operation separately of the switch that forms switch group 25, and carries out according to detectingThe processing (step S2) of the operation of arriving.

For example, in switch process (step S2), detect tone color assigned switch, automatic accompaniment patternThe various switches such as assigned switch of open and close of assigned switch, automatic accompaniment pattern of classificationOperation. In the time that automatic accompaniment pattern becomes unlatching, performance pattern is switched to automatic accompaniment mould by CPU21Formula. Represent that the data of performance pattern are by the Region specification of the regulation of RAM23. Represent tone color or automaticThe data of the classification of accompaniment pattern are kept in the region of regulation of RAM23 too.

Then, CPU21 carries out keyboard processing (step S3). Fig. 4 represents in more detail about thisThe flow chart of the example of the keyboard processing of embodiment. In keyboard is processed, CPU21 is scanning key successivelyThe key (step S11) of dish 11. CPU21, with reference to this scanning result, judges whether to send out about certain keyGive birth to event (step S12). The in the situation that of being judged as "Yes" in step S12, CPU11 judgementWhether this event is that key is opened (button) (step S13).

The in the situation that of being judged as "Yes" in step S13, CPU21 carries out and has been carried out this key and opensThe corresponding pronunciation processing (step S14) of key of opening. In this pronunciation is processed, CPU21 reads storageThe tamber data that melody key in RAM23 is used and represent the data of the pitch corresponding with this key,Temporarily store in RAM23. Process in (the step S6 of Fig. 3) in source of sound pronunciation described later, willThe expression tone color of this temporary transient storage and the data of pitch are given sound source part 26. Sound source part 26 is according to representing soundThe data of look and pitch, by reading Wave data from ROM22, generate tone data. Thus,Produce the musical sound of regulation from loudspeaker 28.

Then, CPU21 for example, by fixed to the pitch information (key number) of the key about there being key to open and buttonTime (for example button moment) to RAM23 preserve (step S15). Button timing can be based on interruptionThe Counter Value of counter calculates.

The in the situation that of being judged as "No" in step S13, generation event is that key is closed (from key). CauseAnd CPU21 carries out about the noise reduction processing (step S16) that becomes the key that key closes. In noise reduction processingIn, CPU21 takes out the data that are included in the expression pitch in this event. In the case,Also process in (step S6) in source of sound pronunciation described later, the data of the expression pitch of this taking-up are givenSound source part 26. The data of sound source part 26 based on giving, by the musical sound noise reduction of this pitch. Then, CPU21About the key that has key to close, the time from key (from the key moment) is preserved to (step S17) to RAM23.

CPU21 judges whether to process and finish (step S18) about whole key events. In stepIn S18, be judged as in the situation of "No", get back to step S12.

If keyboard processing (the step S3 of Fig. 3) finishes, CPU21 carries out chord judgement and processes (stepRapid S4). Fig. 5 is the flow chart that represents the example of processing about the chord judgement of present embodiment. ?In present embodiment, haply using the current melody sound just pronouncing as current melody sound (CurrentMelody) CM, using the melody sound than its previous pronunciation as melody sound (Previous formerlyMelody) PM, using than the current chord name by previous performance as chord name (Previous formerlyChordname) PreCH, based on current melody sound CM, formerly melody sound PM and chord name formerlyPreCH, current chord name (CurrentChordname) CurCH that decision should newly be pronounced. In addition,In the present embodiment, the tonality of melody is made as to c major (CMaj) or A ditty (Amin),About chord name, represent with respect to the number of degrees of keynote with IMaj, IIm etc., these data are stored inIn RAM23 etc. The in the situation that of other tonalities, root sound that can be based on this tonality and " C " (or " A ")Sound between the poor chord name that accompanies with root sound of obtaining of pitch.

In addition, the tonality of melody is not limited to predetermine into c major (CMaj) or A ditty (AMin) situation, also can comprise other large tune, ditty and determine in real time. In the case, certainlyThe classification of fixed tune is more than 1. Also determined tune is stored in RAM23.

But, sometimes should in which bat wait based on button, by the temporal position of button,Whether button is that the figure (continue, carry out successively, jump etc.) of racket head or multiple buttons determinesAbove-mentioned current melody sound CM and formerly melody sound PM. , exist about current by button in realityButton beyond key should be made as the situation of current melody sound CM and about current by the key of buttonPreviously should be made as the formerly situation of melody sound PM by the button beyond the key of button. Below, existDuring chord judgement is processed, step S24～30 relate generally to current melody sound CM and melody sound PM formerlyDecision. The step S31 then carrying out be based on current melody sound CM, formerly melody sound PM andFormerly chord name PreCH determines the processing of current chord name CurCH particularly.

First, CPU21 determine the information of the bat under current time and key information (key open timeCarve or till the time that key is closed), determine in current bat by the key of button, and obtain oughtIn the previous interval (front bat interval) of the bat under the front moment by the information of the key of button (step S21).In step S21, in current bat is the initial of current melody sound CM by the information of the key of buttonValue is the initial value of melody sound PM formerly in the interval beginning of front bat by the information of the key of button.

Then, information and the key information of CPU21 based on clapping, judges bat under current timeBeginning just whether exist by according to key (step S22). In step S23, be judged as the feelings of "No"Under condition, chord name judges that processing finishes. The in the situation that of being judged as "Yes" in step S22, CPU21Current chord name CurCH is copied to formerly in chord name PreCH (step S23).

CPU21 is set as the table appointed information of specifying chord table described later to specify the letter of the 2nd chord tableBreath (step S24). In chord table, be mainly included in button and be the 1st the 1st chord using while clappingTable and the 2nd chord table using beyond it time, be kept at respectively in ROM22. Table is specified letterBreath is which the information that represents to use the 1st chord table or the 2nd chord table, is kept in RAM23.

Then, judge by the temporal position of the key of button, which key clapped by button (step atS25, S26, S28). In the situation that button is the 1st bat, ("Yes" in step S25) or button areIn the 3rd situation of clapping ("Yes" in step S26), CPU21 carries out the 1st and claps the corresponding note of the 3rd bat(note) determine to process (step S27). In the situation that button is the 2nd bat ("Yes" in step S28),Carry out the 2nd and clap corresponding note decision processing (step S29). In addition in step S508, be judged as,In the situation of "No", that is, in the situation that button is the 4th bat, carries out the 4th and clap corresponding note certainlyFixed process (step S30).

In the present embodiment, melody is 4/4ths bats, and 1 trifle is made up of 4 bats. Button isN clap, the timing that refers to button be n clap beginning after, than (n+1) clap beginning in the timeUpper morning.

In the inscape of melody, there is the concept of bat and bat. In addition, in bat, according to oftenIndividual bat and have power, considers the power of above-mentioned bat and melody progress. In addition, also there is syncopation(syncopation) the power situation about moving of etc., according to circumstances clapping. In the present embodiment,Consider the power of clapping and extract the formation sound that forms optimum melody stream, determine that being suitable for chord most sentencesDisconnected current melody sound CM and formerly melody sound PM.

Fig. 6～Fig. 9 represents that clapping the 3rd about the 1st of present embodiment claps corresponding note decision processingThe flow chart of example. As shown in Figure 6, judge whether button claps (step S41) about the 1st.The in the situation that of being judged as "Yes" in step S24, CPU21 changes to table appointed information to represent theThe information (step S42) of 1 table. Then, CPU12 carries out the 1 five degree displacement judgement and processes (stepS43)。

It is to extract five degree displacements (, subordinate and sound (dominant) from melody stream that five degree displacement judgements are processedTo the progress of the sound of advocating peace (keynote)) processing. In the present embodiment, in processing, use and considerThe 1 five degree displacement judgement of chord name process and do not consider the 2 five degree displacement judgement of chord nameProcess. Figure 10 is the flow process that represents the example of processing about the 1 five degree displacement judgement of present embodimentFigure.

As shown in figure 10, CPU21 judgement is kept at the formerly chord name PreCH correspondence in RAM23In which (step S81) of the dominant chord of large tone category. Here, about the 1st of present embodimentDuring five degree displacement judgements are processed, the dominant chord of for example establishing large tone category is " VMaj ", " V7 " and " VIIm7(5) ". The in the situation that of being judged as "Yes" in step S81, formerly melody of CPU21 judgement conduct(PM, the CM) of the group of the value of sound PM and current melody sound CM be whether (F, E), (B, C),Certain (step S82) in (D, C). In step S82, judge from melody sound PM formerly toWhether the motion of current melody sound CM is in the time that the chord of tune solves from dominant to keynote in making progress greatlyMotion.

The in the situation that of being judged as "Yes" in step S82, CPU21 by current chord name CurCH certainlyBe decided to be " IMaj ", its information is preserved to (step S83) to RAM23. Then, CPU21 will representThe information that is the 1st judged result in five degree displacements are processed is preserved (step S84) to RAM23. ?In step S81, be judged as in "No" or step S82 and be judged as in the situation of "No", CPU21 sentencesWhether disconnected formerly chord name PreCH is corresponding to certain (step S85) of the dominant chord of little tone category. ThisIn, in the present embodiment, the dominant chord of for example establishing little tone category is " IIIMaj " and " III7 ".

The in the situation that of being judged as "Yes" in step S85, whether CPU21 judgement (PM, CM)Certain (the step S86) in (G#, A), (B, A), (D, C). In step S86,Judge whether the motion from melody sound PM formerly to current melody sound CM is the chord progress at dittyIn motion while solving from dominant to keynote. The in the situation that of being judged as "Yes" in step S86, CPU21Current chord name CurCH is determined, for " VImin ", this information to be preserved to (step S87) to RAM23.Then, advance to step S84.

The in the situation that of being judged as "No" in step S85, or be judged as "No" in step S86Situation under, CPU21 by be illustrated in five degree displacements process in be the 2nd judged result information toRAM23 preserves (step S88).

If the 1 five degree displacement of step S43 judges that processing finishes, CPU21 judges the 1 five degreeDisplacement judges whether the result of processing is the 2nd result (step S44). In step S44, judgeIn situation for "No", that is, the result of processing in the 1 five degree displacement judgement is the 1st resultSituation under, will be formerly melody sound PM and current melody sound CM do not change initial value to RAM23Preserve, and end process (step S45). The in the situation that of being judged as "Yes" in step S44, CPU21With reference to being kept at the key information in RAM23, judge the bat corresponding with current time tightly beforeBat in whether have button (step S46).

The in the situation that of being judged as "Yes" in step S44, CPU21 is with reference to the button letter of RAM23Breath, judge whether also has button (step S47) after the beginning of tight bat above. At step S47In be judged as "No", mean in tight bat above and this bat respectively by by 4 dieresis.Narrate in the back about the processing in this situation. The in the situation that of being judged as "Yes" in step S47,CPU21 is in the key information being kept in RAM23, after the beginning in tight bat aboveBy the tone period of the key of button, judge whether until current be (step S49) in phonation. ?In step S49, even if be not the button of racket head, as long as it is quilt after the beginning of tight bat aboveButton and being maintained, just corresponding to syncopation, so judge whether the button corresponding to syncopation.

The in the situation that of being judged as "Yes" in step S49, formerly melody sound PM is the former of initial valueShape, on the other hand, after the beginning in tight bat above by the key of button as current melody sound CM,And cutting mark SYN is set to " 1 ", preserve (step S50) to RAM23. To formerly revolveNote PM and current melody sound CM preserve to RAM23. Corresponding to the button of syncopation due to toolThere is the power same with the button of racket head, dispose so same with racket head.

Then,, with reference to Fig. 7, the situation for "No" in step S46 is described. In stepIn S46, be judged as in the situation of "No", CPU21 judges that whether the button in current bat beginning is rightShould bently start sound (step S51). Step S51 can be by CPU21 with reference to being kept in RAM23Key information, judge whether it is that initial key information is realized. In step S51, be judged as "Yes"Situation under, as melody sound PM formerly and provide current melody sound CM. In addition, although can be byCurrent melody sound CM changes initial value, but CPU21 changes to table appointed information to specify the 2nd chordThe information (step S52) of table.

The in the situation that of being judged as "No" in step S51, judge whether more than 8 bats timeButton (step S53). The in the situation that of being judged as "Yes" in step S53, CPU21 revolves currentNote CM maintains the original state of initial value, on the other hand, and as melody sound PM formerly and provide currentMelody sound CM, preserves information (step S54) to RAM23. In step S53, be judged as "Yes"Situation under, more than there is no new button 2 trifles. In the case, the meaning of melody sequence becomesA little less than, thus ignore more than 2 trifles before by the initial value of the formerly melody sound PM of button. In stepIn rapid S53, be judged as in the situation of "No" formerly melody sound PM and current melody sound of CPU21CM maintains the original state (step S55) of initial value.

Then,, with reference to Fig. 8, the situation that is judged as "No" in step S47 is described. ?In step S47, be judged as in the situation of "No", CPU21 judges current melody function (CurrentMelodyFunction:CMF) whether right and wrong and sound (OtherTone:OT) (step S61).Here, current melody function CMF represents that current melody sound CM is with respect to chord name PreCH formerlyFunction. In the present embodiment, CMF is: represent that current melody sound CM is chord name formerlyThe polyphonic ring tone (ChordTone:CT) of the chord constituting tone of PreCH, expression are that current scale (is adjustedProperty) formation sound scale symbol (ScaleNote:CN), represent other sound (not sum sound)Certain in other sounds (OtherTone).

More particularly, in ROM22, preserve and will between chord name and musical alphabet, set up associated revolvingRule menu, CPU21 is with reference to having stood with current melody sound CM and the formerly establishment of chord name PreCHCorresponding value, judges current melody function. Figure 25 is the melody function representing about present embodimentThe figure of the part of one example of table. As shown in figure 25, in melody menu 2500, can be corresponding toObtained the value of regulation by the group of current melody sound CM and the value that formerly chord name PreCH forms. ?In Figure 25, in melody menu 2500, CT represent polyphonic ring tone (for example, with reference to label 2501～2503), SN represents scale symbol (for example,, with reference to label 2511～2513). In addition, in Figure 25,In melody menu 2500, the hurdle (for example,, with reference to label 2521,2522) what is not all recordedRepresent other sounds.

The in the situation that of being judged as "Yes" in step S61, CPU21 will be formerly melody sound PM and working asFront melody sound CM maintains the original state (step S62) of initial value. On the other hand, in step S61, sentenceIn the situation of breaking as "No", CPU21 judges whether current melody function CMF is scale symbol SN (stepRapid S63). The in the situation that of being judged as "Yes" in step S63, CPU21 judges formerly melody soundWhether the difference of PM and current melody sound CM is that 2 semitones are with interior (step S64). At step S64In, judge whether it is so-called progress successively. The in the situation that of being judged as "Yes" in step S64,Or the in the situation that of being judged as "No" in step S63, carry out the 1 five degree displacement processing (stepS65)。

Then, CPU21 processes in (step S65) in the 1 five degree displacement judgement, judges whether to beThe 2nd judged result (step S66). The in the situation that of being judged as "No" in step S66, that is,Be in the situation of the 1st judged result, CPU21 is melody sound PM and current melody sound CM dimension formerlyHold the original state (step S62) of initial value. The in the situation that of being judged as "Yes" in step S66, CPU21Judge current button, whether be the 1st (the step S63) clapping as the button of handling object. ?In step S63, be judged as in the situation of "Yes" formerly melody sound PM and current melody of CPU21Sound CM maintains the original state (step S68) of initial value.

On the other hand, the in the situation that of being judged as "No" in step S67, if right as processingThe button of elephant is the 3rd to clap, CPU21 be given in as melody sound PM formerly than initialFirst melody sound PM more forward 1 by the pitch PPM (step S69) of button. In addition, revolve currentNote CM maintains initial value. This is because forming the musical sound of progress successively in the 3rd claps is to decorateProperty the possibility of sound higher, can think that the original musical sound of domination melodic line is the pleasure before one is clappedSound is suitable.

Then, the situation that is judged as "No" in step S49 is described. As shown in Figure 9,CPU21 determines the later keypad tone (step S71) of racket head in tight bat above, judges determinedThe pitch of keypad tone whether identical with initial CM (step S72). In step S72, be judged as "Yes"Situation under, CPU21 maintains current melody sound CM under initial state, on the other hand, doFor melody sound PM formerly provides the value (step S73) of current melody sound CM. For example, considerIn tight bat above by 8 dieresis with in the order progress melody of " D ", " C ", current batButton is the situation of " C ". The sound of initial " D " of the bat before in the case, considering is tightlyGrace, considers it is not the order from " D " to " C " and be suitable to the order of " C " from " C "When. Therefore, make that formerly melody sound is identical with current melody sound, for phase unisonance continuously.

The in the situation that of being judged as "No" in step S72, after CPU21 judges determined racket headKeypad tone whether all equate (step S74) with melody sound PM formerly. In step S74, judgeIn situation for "Yes", advance to step S63. For example, consider in tight bat above by 16Dieresis has carried out 4 buttons of " D ", " C ", " C ", " C ". In the case, clap because beHead, thus also can consider that " D " is ornamental sound, should be using the button as racket head so have yet" D " as the situation of melody sound PM formerly. So, the later processing of execution step S63.

On the other hand, the in the situation that of being judged as "No" in step S74, formerly melody of CPU21Sound PM and current melody sound CM maintain the original state (step S75) of initial value.

Then, clap corresponding note to the 2nd and determine that processing (step S29) describes. Figure 11～figureThe 14th, represent to clap corresponding note and determine about the 2nd of present embodiment the flow chart of the example of processing. AsShown in Figure 11, CPU21 judges in the 1st claps whether there is no button (step S91). At step S91In be judged as in the situation of "Yes",, in the situation that there is no button, CPU21 will show appointed informationChange to the information (step S91) of specifying the 1st chord table. For example,, when at song midway, beforeThe sound of trifle extends, and the 1st to clap be rest, while clapping next phrase since the 2nd, in this enforcement justIn formula, consider to clap by the sound of button and have and the power of the 1st beating-in sample the 2nd, be used as the 1st to clapWith the 1st chord table of chord table.

In the corresponding note of the 2nd bat is processed, the 1st claps the 3rd claps the 1 five of corresponding note decision processing(step S43) and the processing based on its judged result (step S44, S45) are processed in degree displacement judgementOmit. Step S93～step S97 is same with step S46～S50 of Fig. 6 respectively.

In addition, Figure 12 is the processing of carrying out the in the situation that of being judged as "No" in step S93. StepS101, step S103～S105 are same with step S51, the step S53～S55 of Fig. 7 respectively. ThisOutward, in step S102, except not following the change of table appointed information, with the step of Fig. 7S52 is same.

Then, the situation that is judged as "No" in step S94 is described. As shown in figure 13,CPU21 judges whether right and wrong and sound OT (step S111) of current melody function CMF. In stepThe step S112 advancing in situation for "Yes" in S111 and step S111 and the step S61 of Fig. 8,S62 is same.

The in the situation that of being judged as "No" in step S111, CPU21 judges formerly chord name PreCHWhether be without the chord (step S113) judging beyond chord. As at Figure 21 (particularly step S205)Middle explanation is such, judges chord about nothing, and in processing before, modulation is masked as the value more than " 1 ".So, in step S113, as long as whether the modulation mark that judgement is kept in RAM23 is " 1 "Just can above.

In step S113, being "No", is without the situation that judges chord at chord name PreCH formerlyUnder, CPU21 is as melody sound PM formerly and provide current melody sound CM (step S114). AnotherAspect, the in the situation that of being judged as "Yes" in step S113, is nothing at chord name PreCH formerlyJudge in chord situation in addition, judge whether current melody function CMF is scale symbol SN (stepS115). The in the situation that of being judged as "Yes" in step S63, CPU21 judges formerly melody sound PMWith the difference of current melody sound CM whether be that 2 semitones are with interior (step S116). Step S115 and stepRapid S116 is same with the step S63 and 64 of Fig. 8. In step S115, be judged as "No"In situation, or be judged as "Yes" in step S116 in the situation that, CPU21 is as current chord nameCurCH and provide formerly chord name PreCH (step S117). , incite somebody to action formerly chord name PreCHKeep.

In the 2nd bat or the 4th is clapped, there is the situation of carrying out the chord maintenance that formerly chord name maintains,So having realized suitable chord keeps. In the present embodiment, current melody function CMF be withIn the situation of string sound (CT), or be scale symbol (SN) and be to comply with at current melody function CMFIn the situation of inferior progress, carry out chord maintenance. In the melody of 4 bats, the 2nd bat and the 4th is clapped and isWeak beat. Thereby as long as melody is not emphasized weak beat, the 2nd bat and the 4th chord of clapping are just substantiallyMaintaining the 1st claps and the 3rd chord of clapping.

For example, in the melody shown in Figure 46, have in racket head " C ", " D ", " E ", " F ", " E ",The sound of " D ", " C ", the order of this sound is for making progress successively. In fact, be suitable for the chord of this orderName is IMaj (CMaj). But, if do not perform step the processing shown in S115～step S117,, in the 2nd bat or the 4th is clapped, chord name becomes IMaj (CMaj) in addition. So, as stepShown in S115～S116, carry out under certain conditions chord maintenance, can obtain suitable chord name.

After step S117, the chord in CPU21 RAM23 determines that mark is set to " 1 " (stepRapid S118). This is because in the case, determined current chord name in step S117CurCH, so the processing that does not need follow-up chord to determine.

In addition, the in the situation that of being judged as "No" in step S116, advance to step S112, dimensionBe held in first melody sound PM and current melody sound CM.

The processing in the situation that of being judged as "No" in step S96 as shown in figure 14. The step of Figure 14Rapid S121～step S125 is same with step S71～S75 of Fig. 9. In step S124, sentenceIn the situation of breaking as "Yes", advance to the step S115 of Figure 10, judge that chord keeps.

Then, clap corresponding note to the 4th and determine that processing (step S30) describes. Figure 15～figureThe 16th, represent to clap corresponding note and determine about the 4th of present embodiment the flow chart of the example of processing. The4 clap corresponding note determines that processing and the corresponding note of the 2nd bat determine to process similar.

As shown in figure 15, clapping corresponding note the 4th determines, in processing, to omit having of the 1st button of clappingIt's too late follows its processing (step S91～S92 of Figure 11). In Figure 15, step S131～S135Same with step S93～S97 of Figure 11. In addition, in step S131, be judged as "Yes"In situation, carry out the processing of Figure 12.

The in the situation that of being judged as "No" in step S132, carry out the processing shown in Figure 16. At figureIn 16, step S141～S146 is same with step S111～S116 of Figure 13. Clap the 4thDuring corresponding note is processed, when being judged as "No" or being judged as in step S146 in step S145When "Yes", then carry out the 2 five degree displacement judgement and process (step S147), based on its result, sentenceBreak and whether should carry out chord maintenance.

Figure 17 is the flow process that represents the example of processing about the 2 five degree displacement judgement of present embodimentFigure. In the 2 five degree displacement judgement is processed, only judge the transformation of melody sound, do not consider formerly chordThe chord classification of name PreCH. As shown in figure 17, CPU21 judgement (PM, CM) be whether (F,E), certain (step S151) in (B, C), (D, C). The step S82 of this and Figure 10 be withSample. The in the situation that of being judged as "No" in step S151, CPU21 judgement (PM, CM) isNo is certain (step S153) in (G#, A), (B, A), (D, C). This and Figure 10'sStep S86 is same.

The in the situation that of being judged as "Yes" in step S151, or be judged as "Yes" in step S153Situation under, CPU21 by be illustrated in five degree displacements process in be the 1st judged result information toRAM23 preserves (step S152). On the other hand, in step S153, be judged as the feelings of "No"Under condition, CPU21 is that the information of the 1st judged result is to RAM23 by being illustrated in five degree displacements in processingPreserve (step S154).

In the 2 five degree displacement judge processing be the 2nd judged result in the situation that (in step S148"Yes"), CPU21 provides formerly chord name PreCH (step as current chord name CurCHS149). , keep formerly chord name PreCH. Then, CPU21 by the chord in RAM23 certainlyCalibration will is set to " 1 ". On the other hand, the in the situation that of being judged as "Yes" in step S148, frontEnter step S142, maintain formerly melody sound PM and current melody sound CM.

The in the situation that of being judged as "No" in step S134, carry out the processing shown in Figure 14.

If shown in step S27, S29, S30, determine that with clapping corresponding note processing finishes respectively,, based on by processing revised formerly melody sound PM and current melody sound CM, carry out chord and determineProcess (step S31). Figure 18～Figure 21 represents to determine to process about the chord of present embodimentThe flow chart of example.

As shown in figure 18, CPU21 keeps determining current chord name CurCH by chord, andAnd judge whether that chord determines that mark is not " 1 " (step S161). In step S161, be judged as "No"Situation under, determine that at chord mark is be " 1 " in the situation that, CPU21 is by current chord name CurCHAnd the pronunciation moment is to the region preservation (step S175) of the regulation of RAM23.

The in the situation that of being judged as "Yes" in step S161, determine that at chord mark is not " 1 "Situation under, CPU21 obtains formerly melody sound PM and current melody sound CM (step from RAM23S162). CPU21 judges formerly whether melody sound PM is the bent sound (step S163) that starts. In stepIn S163, for example if judgement do not exist than more front moment of melody sound PM formerly by the sound of button justCan. The in the situation that of being judged as "No" in step S163, CPU21 judges formerly polyphonic ring tone PreCHWhether be without judging chord (step S164).

The in the situation that of being judged as "Yes" in step S163, or be judged as "Yes" in step S164Situation under, CPU21 is as melody sound PM formerly and provide current melody sound CM (step S165).This is because the in the situation that of being judged as "Yes" in step S164, formerly chord name PreCH isWithout judging chord, so it is more appropriate newly to start melody sequence.

Then, CPU21, with reference to melody sequence table, obtains the group (step of the value corresponding with (PM, CM)Rapid S166). Figure 22 is the figure representing about the example of the melody sequence table of present embodiment. As Figure 22Shown in, in melody sequence table 2200, about formerly melody sound PM and the current melody sound of regulationThe group of the CM value of preserving. If be present in melody sequence table with the group of value corresponding to (PM, CM)In 2200, as long as the group of this value is temporarily saved in RAM23 just passable. On the other hand, asFruit is not present in melody sequence table 2200 with the group of value corresponding to (PM, CM), needs only and will showThe non-existent information of group of indicating value is preserved just passable to RAM23.

Then, CPU21 determines tight above by the sound of button (before CM is tight at current melody sound CMThe sound of face) (step S167). Described here is tightly in fact at tight quilt above by the sound of button aboveThe sound of button, also has and situation that formerly melody sound PM is not identical. CPU21 will be at step S167In tight sound and the current melody sound CM above of definite CM compare, judge that their pitch is poorWhether be 5 semitones above (step S168). The in the situation that of being judged as "Yes" in step S168,CPU21 judges that whether current melody sound CM is about the 1st button (step S169) of clapping.

Sometimes in melody sequence, comprise the melody sound that should serve as core, before and after it, exist and decorate conductThe melody sound of the melody sound of core. The melody sound of decorating does not have conventionally compared with melody sound as coreVery large pitch is poor. On the other hand, the poor jump of pitch be certain limit (for example 4 about degree) withOn situation under, it is more that in the sound after jump, intensity becomes larger situation. So, at step S168Middle judgement pitch is poor, carries out different processing based on this difference.

The in the situation that of being judged as "Yes" in step S169, CPU21 judges formerly chord name PreCHWhether continue two trifles above (step S171). The in the situation that of being judged as "Yes" in step S171,CPU21 determines in the 1st chord table as classification and with reference to the hurdle of " jump 2 ", obtains the 1st HeThe chord name (step S172) of the regulation in string table. On the other hand, in step S172, be judged as "No"Situation under, CPU21 determines in the 1st chord table as classification and with reference to the hurdle of " jump 1 ",Obtain the chord name (step S173) of the regulation in the 1st chord table.

Figure 23 is the figure representing about the example of the 1st chord table of present embodiment. In Figure 23, showShow a part for the 1st chord table. As shown in figure 23, in chord table 2300, at least based on formerlyThe function (formerly chord function (PreviousChordFunction): with reference to label 2310) of chord nameAnd the group (for example, with reference to label 2301,2302) of (formerly melody sound PM, current melody sound CM),Determine chord name.

And then, in the present embodiment, arrange " without jump ", " jumping 1 " and " jumping 2 " this 3Individual classification (with reference to label 2311), based on formerly chord function, (formerly melody sound PM, current revolvingNote CM) group and classification decide chord name.

Formerly chord function has these 3 of keynote (TO), sub-dominant (SU) and dominants (DO). DoFor the chord name of corresponding keynote, have " IMaj ", " IM7 ", " IIImin ", " IIIm7 ", " VImin "," VIm7 ". As the chord name of the sub-dominant of correspondence, have " IImin ", " IIm7 ", " IIm7 (5) "," IVMaj ", " IVM7 ", " IVmin ", [IVmM7]. In addition, as the chord name of corresponding dominant,Have " IIIMaj ", " III7 ", " III7sus4 ", " VMaj ", " V7 ", " V7sus4 ", " VIIm7 (5) ". Every kind formerly the corresponding chord name of chord function be for example kept in advance in RAM23.

In addition, in classification, the jump in " jumping 2 " consideration melody sequence and formerly continuing of chord nameContinuous, make the degree of variation of chord larger. On the other hand, in " jumping 1 ", with " jumping 2 "Situation compare, chord change degree less. In addition, the classification of " without jump " as described later,Using the 1st chord table in the situation that, for there is no the classification of " jumping 1 " or " jumping 2 "In situation, use.

For example, if formerly the formerly chord function of chord name PreCH is " keynote ", and (formerlyMelody sound PM, current melody sound CM)=(C, G), classification is " jumping 2 ", from the 1st HeIn string table, obtain " VMaj " (with reference to label 2321). In addition, if chord name PreCH formerlyFormerly chord function is " keynote ", and (formerly melody sound PM, current melody sound CM)=(C,G), classification is " jumping 1 ", obtains " IMaj " (with reference to label 2322) from the 1st chord table.

CPU21 using from the definite chord name of the 1st chord table as current chord name CurCH toPreserve in the region of the regulation of RAM23, and the moment of being pronounced preserves to the region of the regulation of RAM23(step S174, S175).

Then, to being judged as "No" or being judged as "No" in step S168 in step S169Situation describe. CPU21 judges that whether current melody sound CM is chord name PreCH formerlyPolyphonic ring tone (CT) (step S181). The in the situation that of being judged as "Yes" in step S181, CPU21Based on formerly pronunciation moment and the current time of the musical sound of chord name PreCH, judge formerly chord nameWhether the tone period of PreCH is that two bats are with interior (step S182). In step S182, be judged as "Yes"Situation under, CPU21 judges whether cutting mark is " 1 " (step S183) again.

The in the situation that of being judged as "No" in step S183, CPU21 carries out the 2 five degree displacement processing(step S185), judges whether be five from melody sound PM formerly to the transformation of current melody sound CMDegree displacement. Result in the 2 five degree displacement processing is (step S185 the 2nd judged resultMiddle "Yes"), CPU21 provides formerly chord name PreCH (step as current chord name CurCHS186). , keep formerly chord name PreCH.

In step S181, be judged as "No", in step S182, be judged as "No" or in stepIn S185, be judged as in the situation of "No" CPU21 judgement and (formerly melody sound PM, current revolvingNote CM) whether the group of corresponding value be present in (step S187) in melody sequence table. At Figure 18Step S166 in, because the group of value or the non-existent information of group of expression value are kept in RAM23,So by with reference to this information, can carry out the judgement of step S187.

The in the situation that of being judged as "Yes" in step S187, judge whether current melody sound CM aboutThe 1st bat or the 2nd is clapped and table appointed information represents the 1st table (step S188). At step S188In be judged as in the situation of "Yes", CPU21 determines in the 1st chord table as classification and with reference to " nothingJump " hurdle, in the 1st chord table, obtain the chord name (step S189) of regulation. With respect to this,The in the situation that of being judged as "No" in step S188, CPU21 determines with reference to the 2nd chord table, theIn 2 chord tables, obtain the chord name (step S190) of regulation.

Figure 24 is the figure representing about the example of the 2nd chord table of present embodiment. In Figure 24,Represent a part for the 2nd chord table. As shown in figure 24, in chord table 2300, based on formerly andThe function (formerly chord function (PreviousChordFunction): with reference to label 2410) of string nameAnd the group (for example, with reference to label 2401,2402) of (formerly melody sound PM, current melody sound CM),Determine chord name. For example, if formerly the formerly chord function of chord name PreCH be " sub-dominant ",And (formerly melody sound PM, current melody sound CM)=(C, G), gets from the 2nd chord tableObtain " VMaj " (with reference to label 2421).

Then, CPU21 using from the 1st chord table or the definite chord name of the 2nd chord table as current andString name CurCH preserves to the region of the regulation of RAM23, and the moment of being pronounced is to RAM23's(step S191, S175) preserved in the region of regulation.

The in the situation that of being judged as "Yes" in step S187, owing to existing in melody sequence table (First melody sound PM, current melody sound CM) group, so suitable by obtaining with reference to chord tableChord name. On the other hand, the in the situation that of being judged as "No" in step S187, carry out modulation or temporaryTime without judging decision of chord etc. The in the situation that of being judged as "No" in step S187, CPU21Whether the tone period (button time) that judges current melody sound CM is larger than 4 dieresis, that is, beNo pronunciation is clapped long (step S201) than 1.

The in the situation that of being judged as "No" in step S201, CPU21 does not change formerly chord name PreCHAnd former state is as current chord CurCH (step S207). It in step S201, is the situation of "No"Under, very large may not be the intentional button of player, but presses and given as security wrong key because misconnection is tactile. InstituteWith, in the case, do not change chord name, and will be formerly chord name PreCH former state as current andString name CurCH.

The in the situation that of being judged as "Yes" in step S201, CPU21 judges the pronunciation of current melody soundWhether the time (button time) is 3 bats following (step S202). In step S202, be judged as "Yes"Situation under, judge whether modulation mark is below " 2 ". In step S203, be judged as "Yes"Situation under, the value that is kept at the modulation mark in RAM23 is increased progressively (step S205) by CPU21.The in the situation that of being judged as "No" or being judged as "No" in step S202 in step S203, CPU21Carry out modulation processing (step S204).

In the present embodiment, substantially current melody sound CM, revolving of melody sound PM formerly will be comprisedNote is processed with the scale (tonality) of " C ". Thereby, in modulation is processed, as long as calculate after modulationThe pitch of tonality and " C " poor, using poor this pitch preserve as side-play amount to RAM23 just passable.After modulation is processed, by being reduced side-play amount, energy by the key of button number definite musical alphabet by realityThe tonality of enough " C " continues to process.

After step S205, CPU21 judges that whether current melody sound CM is chord name PreCH formerlyPolyphonic ring tone (CT) or scale symbol (SN) (step S206). In step S206, with step S61Equally, CPU21 is as long as with reference to melody menu, judgement and current melody sound CM and chord name formerlyWhether the vertical corresponding value of establishment of PreCH is that polyphonic ring tone or scale symbol are just passable. In step S206, sentenceIn the situation of breaking as "Yes", CPU21 gives formerly chord name PreCH to current chord name CurCH,To keep chord (step S207).

The in the situation that of being judged as "No" in step S207, CPU21 judges chord table with reference to nothing, willThe chord that subtracts (dim) or increasing (aug) is given to current chord name CurCH (step S208). FigureThe 26th, represent relevant present embodiment without the figure of part of an example that judges chord table. Shown in Figure 26Without judging in chord table 2600, can be corresponding to by current melody sound CM and chord name formerlyThe group of the value that PreCH forms and obtain the value of regulation.

Without judge in chord table 2600, empty hurdle (for example,, with reference to label 2601) mean with by oughtThe establishment of value that front melody sound CM and formerly chord name PreCH the form corresponding current melody of having rendered meritorious serviceCan (CMF) be polyphonic ring tone (CT) or scale symbol (SN) (with reference to Figure 25). Thereby, aboutWithout judge in chord table 2600 be empty hurdle by current melody sound CM and chord name PreCH structure formerlyThe group of value becoming, current chord name CurCH can be that nothing judges chord, so save value not. Thereby,Without judging in chord table 2600, be other sounds (OT) about current melody function (CMF)Situation, in store appointment subtracts (dim) or increases certain information of (aug).

CPU21 is from without judging chord table 2600, obtain with by current melody sound CM and chord formerlyThat the establishment of value that name PreCH forms has been stood is corresponding, specify and subtract (dim) or increase certain of (aug)Information, obtain the chord name taking current melody sound CM as root sound. For example,, if current melody soundBe " C# ", formerly chord name is " IMaj ", chord " I#dim " (with reference to label 2611) by name.In addition, if current melody sound beFormerly chord name is " IM7 ", and chord is by name CPU21 is like this by subtracting (dim) or increasing (aug) taking current melody sound CM as root soundChord name determine as current chord name CurCH, preserve to RAM23.

As described above, in the present embodiment, first, will have with the button of the racket head of current batThe current melody sound CM closing with the formerly melody sound PM relevant with the button of the racket head of front bat according to tableShow that the information of which bat, formerly chord name PreCH and button timing etc. revised (the step of Fig. 5Rapid S21～S30). And then, based on current melody sound CM, formerly melody sound PM and chord name formerlyPreCH, determines current chord name CurCH (step S31).

Finish if (the step S4 of Fig. 3) processed in the judgement of chord name, CPU21 carries out automatic accompanimentProcess (step S5). Figure 45 is the stream representing about the example of the automatic accompaniment processing of present embodimentCheng Tu. First, CPU21 judges whether action (step under automatic accompaniment pattern of automatic adjusting equipment 10Rapid S411). The in the situation that of being judged as "Yes" in step S411, with reference to the timer of CPU21 (notDiagram), judge whether current time has reached in automatic accompaniment data the thing about the data of melody soundThe execution timing (step S412) of part.

In automatic accompaniment data, the musical sound that comprises 3 classifications, i.e. polyphonic ring tone, root, rhythmThe data of sound. The data of root and the data of polyphonic ring tone comprise according to the musical sound that should pronounce its pitch,Pronunciation timing and tone period. In addition, the data of rhythm sound are according to the musical sound that should pronounce (rhythm sound)And comprise its pronunciation regularly.

The in the situation that of being judged as "Yes" in step S412, CPU21 carries out basis pronunciation noise reduction placeReason (step S413). In melody pronunciation noise reduction is processed, judge whether the event about processing is soundSymbol open event. Can sending out by the musical sound of the regulation in the data of current time and above-mentioned rootSound timing roughly unanimously judges it is note open event. On the other hand, can by current time withThe pronunciation timing of this musical sound is added to moment after tone period roughly unanimously judges that note closes thingPart.

In the case of being note close event about the event of processing, CPU21 carries out noise reduction processing.On the other hand, if about process event be note open event, carry out the number according to rootAccording to pronunciation processing.

Then, CPU21, with reference to the timer (not shown) of CPU21, judges whether current time reachesTo in automatic accompaniment data about the execution timing (step S414) of the event of the data of polyphonic ring tone.The in the situation that of being judged as "Yes" in step S414, CPU21 carries out chord pronunciation noise reduction processing (stepRapid S415). In polyphonic ring tone pronunciation noise reduction is processed, the polyphonic ring tone execution that has reached pronunciation timing is sent outSound processing, on the other hand, carries out noise reduction processing to the polyphonic ring tone that has reached noise reduction timing.

Then, CPU21 judges what whether current time had reached in automatic accompaniment data about rhythmThe execution timing (step S416) of the event of data. In step S416, be judged as the situation of "Yes"Under, CPU21 carries out the pronunciation of rhythm sound and processes (step S417). In the pronunciation of rhythm sound is processed, rightThe rhythm sound that has reached pronunciation timing generates note open event.

If automatic accompaniment processing (the step S5 of Fig. 3) finishes, CPU21 carries out source of sound pronunciation placeReason (step S6). In source of sound pronunciation is processed, the note open event of CPU21 based on generated,The tone color of musical sound and the data of pitch that expression should be pronounced are given sound source part 26, or expression should be disappearedThe tone color of the musical sound of sound and the data of pitch are given sound source part 26. Sound source part 26 is according to representing tone color, soundThe data of height, the duration of a sound etc., read the Wave data of ROM22, become the tone data of regulation next life.Thus, produce the musical sound of regulation from loudspeaker 28. In addition, CPU21 is based on note close event, toSource of sound 26 is indicated the noise reduction of the pitch that note close event represents.

Finish if (step S6) processed in source of sound pronunciation, CPU21 carries out other and processes and (for example work asFront chord name CurCH and current melody sound CM are to the preservation of RAM23, to the image of display part 15Show, the lighting, turn off the light etc. of LED (not shown): step S7), to step S8 transfer processing.

In step S8, CPU21 judges whether to play and finishes. Particularly, judge non real-time chordWhether correction switch 14 is set is pressed. In the time that this is judged as "Yes", CPU21 will process to stepS9 shifts, and in the time of "No", will process to step S2 and shift. Finish if be judged as to play,Become in RAM23 and preserve as the reality of being brought by a series of performance by the processing of step S7Time chord chord data and the melody data of result that arrange.

In step S9, CPU21 carries out non real-time chord correcting process described later with reference to Figure 27. AsThe non real-time chord correcting process of fruit finishes, and CPU21 finishes the processing of main flow.

Figure 27 is the flow chart representing about the example of the non real-time chord correcting process of present embodiment.

In step S211, CPU21 carries out just verifying processing with reference to Figure 28 and Figure 29 adjusting described later.

In step S212, CPU21 carries out the chord constituting tone checking described later with reference to Figure 30 to be processed.

In step S213, CPU21 carries out dividing checking place with reference to Figure 31 to Figure 34 phrase described laterReason.

In step S214, CPU21 carries out, with reference to Figure 35 and Figure 36 chord described later, Corrections Division is setReason.

In step S215, CPU21 carries out the comparison with reference to Figure 37 melody described later and chord scaleProcess.

In step S216, CPU21 carries out with reference to Figure 38 described later by user's correcting process.

Then, CPU21 finishes non real-time chord correcting process.

Figure 28 and Figure 29 are the flow processs that represents just verifying about the adjusting of present embodiment the example of processingFigure.

In step S221, CPU21 judges whether in song, adjust is 1. Particularly, CPU21Whether the quantity that judgement is kept at the classification of the tune (adjusting in song) in RAM23 is 1. In this songTune is the tune that the resume based on playing the pitch of the melody of input by keyboard 11 determine. This is for example logicalCross and extract the musical alphabet group corresponding with the resume of this pitch, retrieve this musical alphabet group and be all included in whole tone scaleTune (tune) obtain. In retrieval, can consider to use the whole tone exponent character of preserving every kind of tuneTable etc.

In the case of being judged as "Yes" of step S221, step S222 is transferred in processing by CPU21,The in the situation that of "No", processing is transferred to step S234.

In step S222, CPU21 determines the tune based on final melody sound in table and song and transfers in row ratio. Particularly, CPU21 determines table (Figure 39) with reference to the tune based on final melody sound, by songAdjust with final melody sound and compare. For example, according to Figure 39, be " C " if adjusted in song, finally revolveNote is certain of " C, E, G ", owing to adjusting in song in the part corresponding with final melody soundPreserve " C (1) ", so mate in step S223 described later.

On the other hand, be " C " if adjusted in song, final melody sound is " A ", owing to adjusting in songIn the part corresponding with final melody sound, do not preserve data, thus in step S223 described later notCoupling.

In step S223, whether the result in CPU21 determining step S222 mates. In this judgementIn situation for "Yes", no problem in tune judgement, so finishing to adjust, CPU21 judges checking placeReason, the in the situation that of "No", for adjusting is just transferred to step S224 by processing.

In step S224, CPU21 determines in table having the tune being documented in based on final melody soundThe tune of final sound is adjusted as candidate according to preferential precedence. Particularly, CPU21 reference is based on finally revolvingTable (Figure 39) determined in the tune of note, determines that candidate adjusts. For example, determine table (Figure 39) according to adjusting,Final melody sound is in the situation of " A ", preserves F (1), D (2), A in the row of " A "(3). This F, D, A represent possibility is higher in the time that melody finishes with A tune, numeralPreferential precedence. Thereby, in adjusting judgement in real time, be judged as " C " and final melody sound by adjusting in songBe in this situation of A, the preferential higher F furnishing of precedence is that the candidate of bent last part adjusts.

In addition, in Figure 39, only disclose the tune calling greatly and determined table, but the tune that also exists ditty to useDetermine table (not shown).

In step S225, CPU21 transfers in the setting of row chord by final 4 trifles with candidate, in stepIn S226, CPU21 judges whether 4 last trifles conform to finale (cadence) judgement table. ThisA little processing is for verifying the whether no problem processing of bent last part candidate's tune.

For example, in the situation that candidate's tune is " F ", final 4 trifles are carried out to chord with tune " F "Arrange, judge chord function and the finale judgement table (Figure 40) of the 4 initial trifles after chord arrangesThe chord function of bent tail portion whether consistent. In the situation that this is judged as "Yes", CPU21 willProcess to step S227 and shift, the in the situation that of "No", will process to step S231 and shift.

The finale judgement table of Figure 40 is that the part of dividing in bent tail portion and song represents possible endThe table of the form of bent (cadence) (stopping shape). In addition, also can append prelude part or hook symbol (hook)Part etc. and further sectionalization. " T " of Figure 40 represents keynote, and " D " represents dominant, " S "Represent sub-dominant.

In step S227, whether CPU21 reinstates candidate from bent head and adjusts checking no problem. This processingThe situation that the 4 last trifles of adjusting candidate are consistent with the chord function of the bent tail portion of finale judgement tableUnder carry out. For example, in the situation that candidate's tune is " F ", bent 4 last trifles are with adjusting " F "Determine, but CPU21 reads the bent head from (the keyboard processing of Fig. 4) inputted in real time from RAM23Melody sound data, whether verify and adjust " F " just to set up from bent head.

In step S228, whether CPU21 judges under candidate adjusts no problem. Particularly,CPU21 judges whether that in step S227 candidate adjusts just establishment from bent head. Be judged as "Yes" at thisSituation under, CPU21 will process to step S230 shift, the in the situation that of "No", will process toStep S229 shifts.

In step S229, CPU21 is modified to two in the place of contradiction by tune. Particularly,CPU21 judges from bent head to which part can not adjust as candidate according to the result of step S227Vertical, from bent head to adjust as candidate invalid position and from candidate tune to open begin the position of setting up toBent is last, and tune is divided into two. For example, adjusting judge song in real time adjusting judgement in is " C ", alsoAnd it is in the situation of " F " that candidate adjusts, and is divided into " C " and " F " these two tune. Then, will processShift to step S221.

In step S230, because just adjusting, candidate from bent head sets up, so determining, adjusts CPU21,And finish to adjust judgement checking to process.

In step S231, CPU21 judges whether to adjust the next candidate who determines table. Particularly,Retrieval is adjusted and is determined that table (Figure 39) judges. For example, be that " A ", candidate's tune are at final melody soundIn the situation of " F ", adjust as next candidate, have " D " as the tune of the 2nd preferential precedence.On the other hand, be that " A ", candidate adjust be " A " in the situation that at final melody sound, do not exist nextCandidate's tune. In the situation that this is judged as "Yes", CPU21 will process to step S232 and shift,The in the situation that of "No", will process to step S233 and shift.

In step S232, CPU21 adjusts candidate to replace with judge next in step S231Candidate's tune, will process to step S225 and shift.

In step S233, CPU21 does not revise tune, and finishes to adjust judgement checking to process.

In step S234, CPU21 judges whether the tune in song is two. Be judged as "Yes" at thisSituation under, CPU21 will process to step S235 shift, the in the situation that of "No", will process toStep S237 shifts.

In step S235, CPU21 judged first adjust with song in the difference adjusted be whether+1 semitone,Certain in+2 semitones ,+3 semitones. This processing is to judge whether to have carried out so-called up modulationProcessing. In the situation that this is judged as "Yes", CPU21 will process to step S236 and shift,In the situation of "No", will process to step S240 and shift.

In step S236, CPU21 determines tune, finishes to adjust judgement checking processing.

In step S237, CPU21 has judged first tune with finally whether tune is identical. Be judged as at thisIn the situation of "Yes", CPU21 will process to step S238 and shift, the in the situation that of "No", and willProcess and shift to step S240.

In step S238, CPU21 judges whether 4 last trifles conform to finale judgement table. ToolBody, CPU21, about playing first tune, in the song with reference to finale judgement table (Figure 40), has judged firstChord function in the song of the chord function of the 4 last trifles of adjusting and finale judgement table (Figure 40) isNo consistent. On the other hand, about final tune, with reference to the bent tail portion of finale judgement table (Figure 40),The chord function of the final 4 last trifles of adjusting of judgement and the bent tail portion of finale judgement table (Figure 40)Chord function whether consistent. In the situation that this is judged as "Yes", CPU21 will process to stepS239 shifts, and the in the situation that of "No", will process to step S240 and shift.

In step S239, CPU21 has determined the first final tune that is in harmonious proportion. For example,, at step S238In, only play first tune unanimously if be judged as, only determine first tune. In addition, if be judged as onlyAdjust eventually unanimously, only determine final tune. And then, finally adjust both consistent if be judged as first mediation,Determine first tune and finally adjusted.

In step S240, CPU21 has judged whether that checking is not adjusted. Be judged as the feelings of "Yes" at thisUnder condition, CPU21 will process to step S241 and shift, and the in the situation that of "No", finish to adjust judgement to testCard is processed.

In step S241, the large ditty of CPU21 reference relation is used judgement table, judges after tune is determined4 trifles are with the interior chord whether having in this table. Particularly, the large ditty of CPU21 reference relationUse judgement table (Figure 41), judge adjust whether have in 4 trifles after determining the homophony of this table independent andString.

For example, in the situation that tune has 3, be " C ", first a tune between final tune playing first tuneTune be belong in the situation of adjusting (adjusting as the genus that plays the first homophony C adjusting is G), judge and belonging to tune4 initial trifles are using interior V7 (G7) or the IIm (Dm) whether existing as homophony independence chord.

Here, homophony independence chord is described. For example, in the situation that homophony is C, belongs to and adjustingG is the tune of the 4th sound (fa) rising semitone of homophony only, if by homophony C (by do, re, mi,Fa, so, la, si forms) adjust G (by so, la, si, do, re, mi, fa# formation) ratio with genus, adjust in G and do not comprise fa at genus. Thus, as G7 or the Dm of the chord that comprises fa be notBelong to the chord of adjusting G, but the chord of homophony C. In the present embodiment, under this meaning, useThe title of homophony independence chord.

In step S242, CPU21 judges in step S241 whether mate. Be judged as "Yes" at thisSituation under, CPU21 will process to step S243 shift, the in the situation that of "No", will process toStep S248 shifts.

In step S243, CPU21 is modified to former tune from the place of coupling. For example, only from homophonyRise at the position that vertical chord exists, and is modified to homophony (playing first tune).

In step S244, CPU21 judges whether 4 last trifles conform to finale judgement table. ?In this processing, be used in step S243 in the song of revised tune with reference to finale judgement table (Figure 40),Judge in the chord function of 4 last trifles and the song of finale judgement table (Figure 40) of revised tuneChord function whether consistent. In the situation that this is judged as "Yes", CPU21 will process to stepS245 shifts, and the in the situation that of "No", will process to step S246 and shift.

In step S245, CPU21 determines the tune (revised tune) of this part, will process to stepRapid S247 shifts.

In step S246, CPU21 judges whether remaining tune is 1. Be judged as "Yes" at thisSituation under, CPU21 will process to step S222 shift, the in the situation that of "No", will process toStep S247 shifts.

In step S247, CPU21 has judged whether that checking is not adjusted. Be judged as the feelings of "Yes" at thisUnder condition, CPU21 will process to step S241 and shift, and the in the situation that of "No", finish to adjust judgement to testCard is processed.

In step S248, CPU21 judges whether 4 last trifles conform to finale judgement table. ?In this processing, judge in the song of table (Figure 40) with reference to finale with not verifying to adjust, judge what checking was adjustedThe chord function of 4 last trifles and finale judge chord function in the song of table (Figure 40) whetherCause. In the situation that this is judged as "Yes", CPU21 will process to step S245 and shift, in "No"Situation under, will process to step S249 and shift.

In step S249, CPU21 judges whether to have checked same homophony. , CPU21 is for workThe same homophony of using the hypomere of judgement table (Figure 41) for relative keys judges whether to have checked homophonyHaving or not of the existence of independent chord. In the situation that this is judged as "Yes", CPU21 will process to stepRapid S246 shifts, and the in the situation that of "No", will process to step S250 and shift.

In step S250, CPU21, using next relative keys as confirming object, will process to stepRapid S241 shifts. For example, if gone inspection to belonging to transferring in, will serve as next (its hypomere)The subordinate of relative keys adjusts as next confirmation object.

Figure 30 is the flow chart that represents the example of processing about the chord constituting tone checking of present embodiment.The in the situation that of in real time automatic chord arranges middle appoggiatura or is present in strong beat through graces such as sounds, haveTime because of this grace to chord setting bring impact chord mistake is set. So, this Zhi Peiyin checkingProcess the error correction for such chord is arranged, in the present embodiment, according to each trifleExtract and from melody sound, removed the chord constituting tone after grace, checking is set up by this chord constituting toneChord whether identical with the chord that in real time chord arranges.

First, in step S261, CPU21 is for there is sound more than 1 bat in this trifle, according toDuration of a sound order is from long to short extracted 3 sounds. Particularly, the work of reading and saving in RAM23Chord data and the melody data of the result arranging for the real-time chord based on a series of performance, forIn this trifle, there is sound more than 1 bat, extract 3 sounds according to duration of a sound order from long to short. Here,So-called this trifle is the trifle as the handling object of CPU21, at first using the 1st trifle as processingObject.

In step S262, CPU21 judges whether 3 sounds that extract are included in real-time chord settingChord constituting tone in. Particularly, CPU21 judges with reference to the chord modulator of Figure 43. ExampleAs, be IMajor (I is large) at the chord of chord setting in real time, judge at step S261Or whether 3 sounds that extract in S263 are as chord constituting tone (CT) " C, E, G ".In the situation that this is judged as "Yes", CPU21 will process to step S264 and shift, in "No"In situation, will process to step S263 and shift.

Here,, if 3 sounds that extract are chord constituting tone (CT), these 3 sounds are dominationThe sound of property.

In step S263, CPU21 divides half by trifle, extracts 3 according to duration of a sound order from long to shortIndividual sound. Then, will process to step S262 and shift.

In step S264, CPU21 judges in trifle, whether there is chord melody sound in addition. Specifically, in the trifle of the handling object as CPU21, exist and carried by step S261 or step S263Sound beyond 3 sounds that take out and with reference to the chord modulator of Figure 43 and this sound not to be chord formIn the situation of sound (CT), this sound is the melody sound beyond chord. Be judged as the situation of "Yes" at thisUnder, CPU21 will process to step S265 and shift, and the in the situation that of "No", will process to stepS270 shifts.

In step S265, CPU21 judges whether these sounds comprise grace. Particularly, CPU21Judge with reference to grace database (Figure 42). In the situation that this is judged as "Yes", CPU21To process to step S266 and shift, the in the situation that of "No", will process to step S267 and shift.

Here with reference to Figure 42, grace database is described. This grace database is for sentencingBreak and whether have grace (chord structure in strong beat (at 4 bat in the situation that, being that 1 bat and 3 is clapped)Sound beyond audio) database.

For example, according to the example of Figure 42, the in the situation that of 4 bat, in the 1st claps (strong beat), haveGrace (for example, appoggiatura), the 2nd beyond chord constituting tone is clapped chord constituting tone in (weak beat),And the 2nd chord constituting tone of clapping compared with the 1st sound of clapping in high or low whole tone (or semitone)In the situation of relation, the 1st sound of clapping is judged as to grace. It is also same clapping about the 3rd bat, the 4thSample.

In addition, although do not illustrate in Figure 42, also can judge and have or not 2 bats, 3 bats etc.,Grace beyond 4 bats.

In step S266, CPU21 removes grace, and the chord that result is set with real-time chord carries outRelatively. Particularly, the chord that the real-time chord of CPU21 reading and saving in RAM23 arranges,Whether the sound that the trifle of the handling object after grace has been removed in judgement is with the chord modulator of Figure 43The chord constituting tone (CT) that each chord is corresponding.

In step S267, CPU21 compares with the chord that real-time chord arranges result. Concrete andSpeech, the chord that the real-time chord of CPU21 reading and saving in RAM23 arranges, judges handling objectThe sound of trifle be whether the chord constituting tone (CT) corresponding with each chord of the chord modulator of Figure 43.

In step S268, whether the result of the comparison in CPU21 determining step S266 and S267Coupling (step S266 or S267 be judged as "Yes" (coupling) or "No" (not mating)).In the situation that this is judged as "Yes", CPU21 will process to step S270 and shift, in "No"In situation, will process to step S269 and shift.

In step S269, CPU21 judges whether this overriding sound is set up as chord. Concrete andSpeech, CPU21 is with reference to the chord modulator of Figure 43, judge in step S266 or S267 comparisonWhether sound is chord constituting tone (CT). In the situation that this is judged as "Yes", CPU21 will processShift to step S272, the in the situation that of "No", will process to step S270 and shift.

Like this, conclusivelying show according to melody sequenceIn the situation of five degree displacements, using current chord name CurCH as keynote, form the termination of chord progress.

In addition, CPU21 processes in (Figure 17) in the 2 five degree displacement judgement, from melody sound formerlyPM to current melody sound CM represent predefined, from the formation sound of dominant chord to keynote chordForm in the situation of transformation of sound, provide as current chord name CurCH the chord that is equivalent to keynoteName. Here, even if formerly chord name PreCH is not dominant chord, according to melody sequence clearlyRepresent in the situation of five degree displacements, also using current chord name CurCH as keynote, form chord progressTermination.

And then, CPU21 process by the 1 five degree displacement judgement or the 2 five degree displacement judgement is processed,And do not give in the situation of chord name that is equivalent to keynote as current chord name CurCH, as working asFront chord name CurCH and provide formerly chord name PreCH. Thus, can realize chord keeps.

In addition, in the present embodiment, possess: the 1st chord table, preserve at current melody sound CMAbout in the 1st situation of button of clapping with formerly melody sound PM, current melody sound CM and formerly chordName information PreCH has set up corresponding chord name; And the 2nd chord table, preserve at current melodyIn the situation of button beyond sound CM claps about the 1st with formerly melody sound PM, current melody sound CMAnd formerly chord name PrCH has set up corresponding chord name, CPU21 is according to button timing, with reference to the 1stChord table or the 2nd chord table. Thus, can obtain the chord name different according to bat. In addition, logicalCross reference table, can determine in real time chord name.

And then, in the present embodiment, the formerly melody sound PM based on determined and current melody soundCM does not exist corresponding chord name in the 1st chord table or the 2nd chord table, as working asFront chord name CurCH and give increasing (aug) or subtract (dim) such without judging chord. Thus,Even in the situation that formerly melody sound PM or current melody sound are not chord constituting tone or scale symbol,Also can in melody, give and less have the chord of awkward sense name.

And then in the present embodiment, CPU21 is with reference to revolving chord table according to current without judgingNote CM, formerly melody sound PM and chord name PreCH formerly, judgement should be made as increasing (aug) orSubtract which chord in (dim).

The present invention is not limited to above embodiment, the model of the invention of recording at claimsIn enclosing, can carry out various changes, these changes are also contained in scope of the present invention certainly.

For example, in the above-described embodiment, bat is made as to 4 bats, but if 3 bats or 6Bat also can adopt the present invention. For example,, the in the situation that of 3 bat, as long as use in above-mentioned processingAbout the 1st clap～the 3 clap processing just can. In addition, 6 bats have been thought of as two 3 bats,Use the above-mentioned the 1st to clap the～the 3 processing of clapping. In addition, the 4th clap～the 6 clap if with the 1st clap～The 3rd beating-in sample is disposed and to carry out identical processing just passable.

In addition, in the above-described embodiment, at c major (CMaj) or A ditty (Amin)In tonality, can obtain using the chord name with respect to the number of degrees of keynote (root sound), but not limitIn this, also can adopt the present invention about other tonalities. In the case, for example, if melody isLarge tune, if calculate the root sound of tonality of this melody and the pitch of " C " is poor, using poor this pitch asSide-play amount, offset value is saved in RAM23 just passable. In processing, by will be by realityThe musical alphabet of being specified by the key of button number reduces side-play amount, can carry out and process with the scale of " C ".
