Embodiment

For keyboard instrument in detail the present invention is described in detail.

This musical instrument, it is including but not limited to the music element data storehouse of following kind: tune, speed, beat, tone color, knit body, chord, pitch, and these music elements can be pre-stored in the computer readable file of midi format in the media such as the chip of musical instrument.Its built-in system workflow is:

Part I, answers setting or the selection of player, determining section music element before player plays;

Part II, in player's playing procedure, divides music element to player's recommended unit;

Part III, repetition Part I and Part II are until played.

As Fig. 1, i.e. total figure of the present invention.

Part I is divided into again:

Step one, player's start up system, comprises all music element data storehouses and processor;

Step 2, dotted line frame as shown in the Reference numeral 2 in Fig. 1, player selectes corresponding tune, speed, beat, tone color respectively from database, if do not selected, then processor is considered as these four each one of music element that player have selected processor acquiescence;

Step 3, dotted line frame as shown in the Reference numeral 3 in Fig. 1, generate and multiplely knit body, player selects one; Meanwhile, processor recommends one group of chord optional to player, and if do not selected, then processor is considered as one or more chords that player selects to give tacit consent to;

Step 4, all music elements of step 2 and step 3 synthesize accompaniment tone by processor, accompany when player plays after determining;

Step 5, dotted line frame as shown in the Reference numeral 5 in Fig. 1, under accompaniment tone, after the chord in step 3 is determined, processor recommends one group of pitch for choosing to player; Select, then form a part for performance; Do not select, then, under accompaniment tone, player plays out many pitches voluntarily according to the period.

Part II contains again:

Step 6, dotted line frame as shown in the Reference numeral 6 in Fig. 1, the end of any time period in performance, the current selected chord of player is known by processor, and processor calculates through algorithm one and recommends to player one group of chord making new advances, and player is selected, then form accompaniment; Or player does not select, processor is then optional in the chord group of newly recommending or give tacit consent to one or more, forms accompaniment;

After chord is determined, through one group of pitch that algorithm two calculated recommendation makes new advances, player selectes one or more pitch and continues to play, or player does not select, and plays voluntarily with any pitch, until subsequent period.

Part III comprises again:

Step 7, dotted line frame as shown in the Reference numeral 7 in Fig. 1, at subsequent period, single or multiple repeats Part II, until arbitrary period;

Step 8, terminates, or repeats from step 2, dotted line frame as shown in the Reference numeral 8 in Fig. 1.

Step 8, while selection terminates, is recorded all period pitch stream previously played out, with fixed tune, speed, beat, tone color, knits together with body, all music elements of chord, and generating one can the file of repeatedly playback, such as MIDI file.

In all music elements, after player's selected velocity, beat, tone color, synthesize percussion music by processor, sound each period in player plays all can be used for playing as a setting, dotted line frame as shown in the Reference numeral 9 in Fig. 1.

In Fig. 1, with the arrow of dotted line, represent that step 6 can repeatedly repeat in the different performance periods, namely system is played in arbitrary period player, at the end of the trifle of such as each melody, all according to the chord of current broadcasting/selected, recommend the new chord mated to player, then recommend again new pitch according to this new chord, afterwards, player or system are selected this chord and pitch and are continued to play, until next period/trifle.

Dotted arrow also represents that the introducing of period is played in percussion music accompaniment at each, alternatively.

Current broadcasting or selected chord are all the codes of pre stored data in system, can be embodied by the key assignments that the many alternative button on musical instrument sends to processor.Recommend, selected pitch button, too so.

The rule of chord recommended by the processor of musical instrument system to player, i.e. algorithm one, as shown in Fig. 1 upper right corner.The rule that algorithm one contains is as form 1, as follows:

To the code of the chord of CPU feedback	The code of the chord that musical instrument system is recommended to player
		I	II，III，IV，V，VI
II	V 7，III 7
		III	V，IV
III 7	VI
		IV	V，II，VII
V	I，IV，VI，III
		V 7	I
VI	II，IV，III，V
		VII	III 7

Form 1

" code to the chord of CPU feedback " of form left column, be " current selected chord " in FIG, right row " code of the chord that musical instrument system is recommended to player " are " chord group one ", " chord group two " ... until " chord group N " in FIG.

Roman number I in form 1, II, III, III ₇, IV, V, V ₇, VI, VII be the code of each group of chord, the chord music theory statement symbol that Ye Shi global music circle is conventional, according to form 2, they represent the some chords under a certain mode respectively, such as: under G adjusts, III then represent chord " ^#fDB ".Nine chord codes of these I ~ VII, on musical instrument of the present invention, so that keyboard can embody the button of flashing one by one, as shown in Figure 2, whenever a key flash, can be musical instrument system recommends prompting from some chords to player:

Roman number in Fig. 2, not only represents the many chord buttons in musical instrument card of the present invention, also represents the many chords in form 2 under each mode, and chord packet behind, as MIDI file.

Form 2

Form 2 is chord code and the corresponding table between button with the chord data APMB package under modes many on musical instrument.

The recommendation rules of chord code in form 1 is set forth in further citing:

Such as: I---the II of the 1st row, III, IV, V, VI, namely mean at player's selected some tune (as F adjusts) on musical instrument of the present invention, play when any one (except the first) music measures (in FIG i.e. so-called each " period "), when the chord (such as: player have selected CAF chord by button value I) that musical instrument built-in system CPU is selected in a upper trifle by player, namely " current selected chord " in Fig. 1, when having known that current chord is in I class, so before next music measures (in FIG i.e. next " period ") is arrived, system can flash (as Fig. 2) II in musical instrument card, III, IV, V, these keys of VI, namely musical instrument system recommends II in form 2 to player, III, IV, V, the D that VI is corresponding under F adjusts ^bbG, ECA, FD ^bthese chords of B, GEC, AFD, so player is when seeing that these buttons flash, then can optional one, as abandoned selecting, so just choosing one of this group chord synchronously to play when player freely plays melody sound as accompanying by system default, making the melody sound that selected chord and player play out, sounding seeming very harmonious coupling from the angle of traditional music theory.Meanwhile, due to more than one of the chord recommended, this creates melody certainly with regard to what make player that different chords can be selected to go coupling different at every turn, forms different aesthetic method and musical works.Each chord code in form 1, the chord key code namely in musical instrument card of the present invention be all same recommendation principle, that is musical instrument system is recommended the rule of chord to player.The many chords held in form 2 are that territory, all parts of the world, each clansman's class are for thousands of years to the set of music aesthetics experience.Under certain mode, these chords coordinate the melody under the certain rule played out with player, and its formed sound stream of forming a connecting link can be rated as harmony to the aesthetic feeling of the mankind.

Each is ECA, FD such as ^bthis type of chord of B is exactly packet one by one in fact, is pre-stored within system with MIDI file layout, can be at any time etc. to be called.

Other eight kinds of chord codes in form 1, in like manner.
