  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram showing the overall configuration of an electronic keyboard instrument according to an embodiment of the present invention. FIG. 2A is a schematic plan view of the periphery of the keyboard portion of the musical instrument.

  As shown in FIG. 1, the electronic keyboard instrument includes a detection circuit 3, a detection circuit 4, a ROM 6, a RAM 7, a timer 8, a display device 9, an external storage device 10, a MIDI interface (MIDII / F) 11, a communication interface (communication). I / F) 12, a light emitting unit 19, a sound source circuit 13 and an effect circuit 14 are connected to the CPU 5 via a bus 16.

  Further, the performance operator 1 is connected to the detection circuit 3, and the setting operator 2 including a plurality of switches for inputting various information is connected to the detection circuit 4. The performance operator 1 includes a key K (white key WK, black key BK) in the keyboard unit KB for inputting pitch information, and the setting operator 2 includes menu switches (SW) 21, 22, 23 and shift switches (SW) 24 and 25 are included (FIG. 2A).

  The display device 9 is composed of a liquid crystal display (LCD) or the like, and displays various information such as musical scores and characters. A timer 8 is connected to the CPU 5, and another MIDI device 100 is connected to the MID II / F 11. A server computer 102 is connected to the communication I / F 12 via a communication network 101, and a sound system 15 is connected to the sound source circuit 13 via an effect circuit 14.

  The detection circuit 3 detects the operation state of the performance operator 1, and the detection circuit 4 detects the operation state of the setting operator 2. The CPU 5 controls the entire apparatus. The ROM 6 stores a control program executed by the CPU 5 and various table data. The RAM 7 temporarily stores various input information such as performance data and text data, various flags, buffer data, calculation results, and the like. The timer 8 measures the interrupt time and various times in the timer interrupt process. The external storage device 10 stores various application programs including the control program, various music data, various data, and the like.

  The MIDI I / F 11 inputs a MIDI (Musical Instrument Digital Interface) signal from an external device such as another MIDI device 100 or outputs a MIDI signal to the external device. The communication I / F 12 transmits / receives data to / from the server computer 102 via the communication network 101, for example. The tone generator circuit 13 converts the performance data input from the performance operator 1 or preset performance data into a musical sound signal. The effect circuit 14 gives various effects to the musical sound signal input from the sound source circuit 13, and the sound system 15 such as a DAC (Digital-to-Analog Converter), an amplifier, and a speaker performs the musical sound signal input from the effect circuit 14. To sound.

  Examples of the external storage device 10 include a USB memory, a flexible disk drive (FDD), a hard disk drive (HDD), a CD-ROM drive, and a magneto-optical disk (MO) drive. When the control program is not stored in the ROM 6, the control program is stored in the external storage device 10, and by reading it into the RAM 7, the same operation as when the control program is stored in the ROM 6 is performed. It can be made to CPU5.

  FIG. 2B is a diagram illustrating the relationship between one key K and the light emitting unit 19. In this musical instrument, each key K of the keyboard KB has a light emitting function. This light emission function is sufficient if each key K can emit light individually, and a known configuration can be adopted. For example, as shown in FIG. 2B, a light emitting unit 19 made of an LED provided below each key K irradiates the key K from below, and the light transmitted through the key K is visually recognized. The light emission of the light emitting unit 19 is controlled by the CPU 5 through a light emitting circuit (not shown). However, the present invention is not limited to this, and a configuration in which light is applied to the key pressing surface from an LED provided behind each key K is also conceivable. Alternatively, LEDs arranged in a straight line at the edge of the panel portion behind the key K may be caused to emit light. The configuration for realizing the light emitting function is not limited, and it is sufficient that the CPU 5 can control the light emission.

  This light emission function is used for a so-called performance operation guide function in which a key K to be pressed next is indicated in accordance with performance guide data corresponding to performance data. Further, it can also be used to make the depressed key K emit light during normal manual performance.

  The menu switches 21, 22, and 23 shown in FIG. 2A are switches for setting a learning menu related to “play”, “listen”, and “get used”, respectively. As a learning menu, one of “play”, “listen”, and “get used” is selected by the user operating the menu switches 21, 22, and 23.

  FIG. 3 is a block diagram showing the correspondence between performance guide processing and guide data.

  As described above, this musical instrument has a function of performing a performance guide for instructing key operations for music performance. The performance guide process includes a first guide process, a second guide process, and a third guide process. Guide data used for the performance guide includes first edited music guide data D1, second edited music guide data D2, and original music guide data D3. The original music guide data D3 is edited and generated based on the original music performance data D0 which is the performance data of the original music. The first edited music guide data D1 and the second edited music guide data D2 are both generated based on the original music guide data D3, but may be generated based on the original music performance data D0.

  These data D0 to D3 are all configured as sequence data such as MIDI data. In the present embodiment, the data D0 to D3 are prepared in advance and stored in the ROM 6 or the external storage device 10, and are read out to the RAM 7 when used. Note that only the original musical piece performance data D0 may be stored when the musical instrument is shipped, and the guide data D1, D2, and D3 may be generated before the performance guide processing. The guide data D1, D2, and D3 include at least event data for instructing the key K to be pressed by light emission, but may further include event data for generating an accompaniment.

  The original music performance data D0 is used for reproduction processing for demo performance of music. Guide data D1, D2, and D3 are used for the first, second, and third guide processes, respectively. The first, second, and third guide processes are alternatively executed. Details of each guide process will be described later.

  In the present embodiment, piano performance music is exemplified as the practice target music, and the guide data D1 to D3 used in the performance guide are data instructing key operations of the left hand and the right hand.

  FIG. 4 is a diagram showing a part of the score of the music to be practiced by the performance guide. The practice target song illustrated in FIG. 4 is “For Elise” by Beethoven. When the reproduction process is performed based on the original music performance data D0, the reproduction according to the score shown in FIG. 4 is performed.

  The original music guide data D3 is guide data for instructing the keyboard performance to be performed according to the score shown in FIG. 4 in the third guide processing. Usually, each note or performance tempo is the original music performance. It is the same as that of data D0. The third guide processing using the original music guide data D3 is a known guide mode that is generally performed in the past. For example, the procedure is such that the key to be pressed next is emitted, and when the correct key is pressed, the key to be pressed next is emitted, and thereafter the instruction keys are sequentially advanced.

  FIG. 5 is a diagram showing a part of the second edited music guide data D2 as a score, and particularly shows a portion corresponding to the range of step 1 which is a practice step in the score of FIG. When the second edited music guide data D2 is edited and generated from the original music guide data D3, the note length, tempo value, and time signature are converted.

  First, the second edited music guide data D2 is equivalent to data obtained by expanding all the notes in the original music guide data D3 with an even expansion ratio R (here, R = 4). The tempo value in the second edited music guide data D2 is 200, which is smaller than the product of the tempo value 100 in the original music guide data D3 and the expansion ratio R (100 × 4 = 400). ing. The time signature of the original music guide data D3 is 3/4, but the second edited music guide data D2 is 4/4 time. In FIG. 5, only the corresponding part of Step 1 is shown, but such conversion is applied to the entire music.

  The second guide process using the second edited music guide data D2 differs from the third guide process only in the guide data to be used, and it is not necessary to provide a difference in the control mode. However, a metronome sound may be generated at the start of the performance guide. In this case, the metronome sound is assumed to be performed with an even time signature (4 time signature) in the second edited music guide data D2.

  As described above, in the second guide processing using the second edited music guide data D2, it is possible to practice with the performance guide with an even time signature (for example, 4 time signature) regardless of the time signature of the original music piece. For beginners, even time signatures such as 4 beats are easier to learn and learn than odd beats such as 3 beats. Further, since the tempo value in the second edited music guide data D2 is smaller than the multiplication value of the tempo value in the original music guide data D3 and the expansion ratio R, it is determined by the performance guide at a slower actual speed than the original music. Can practice. Therefore, the beginner can smoothly enter practice by the second guide process using the second edited music guide data D2.

  In order to perform the performance guide with an even time signature, the expansion ratio R is not limited to 4 and may be an even number. Alternatively, in order to be able to perform the performance guide with four beats, the expansion ratio R is changed so that the note with the shortest note length in the original song guide data D3 is converted into a quarter note in the second edited song guide data D2. The value may be set to such a value.

  FIG. 6 is a conceptual diagram showing the relationship between the original song guide data D3 and the first edited song guide data D1.

  As shown in FIG. 6, the original music guide data D3 is divided into a plurality of sections such as “sections a, b, c...” From the head of the music, and the divided sections are connected to form the first edited music guide data. D1 is edited and generated. The divisions divided in the original music guide data D3 correspond to the practice steps (steps 1, 2, 3,...) That are the divisions in the first edited music guide data D1. A practice step (hereinafter, also simply referred to as “step”) corresponds to a part of a short phrase in a song and is a unit of practice. However, there may be omitted sections in the original music guide data D3.

  In the example shown in FIG. 6, section a corresponds to step 1, sections b and d correspond to step 2, section f corresponds to step 3, section g corresponds to step 4, and section h corresponds to step 5. The sections c and e are omitted. In the first edited music guide data D1, if divisions are called in stages, each step is a middle division, and each step is further divided into small divisions. For example, step 1 is composed of subsection 1 and subsection 2. Step 3 consists of subsections 1, 2, and 3. Some steps, such as steps 4 and 5, have a single subsection and substantially coincide with the middle section.

  A mode of dividing the original music guide data D3 will be described with reference to FIG.

  Although there is no limitation on the location where the original song guide data D3 is divided, the boundary between adjacent steps in the first edited song guide data D1 is, for example, finger penetration, finger crossing, or finger change in key operation for piano performance. (Hereinafter, these are collectively referred to as “finger holes”). That is, when editing and generating the first edited music guide data D1, the original music guide data D3 is divided into a plurality of steps at locations where finger penetration or the like occurs.

  Here, the “finger pass” is a technique in which the thumb passes under the middle finger or the index finger to play the ascending sound string. “Finger crossing” (also referred to as “finger straddling”) is a technique of playing a descending sound string with a middle finger or index finger straddling over the thumb. “Finger change” is a technique in which after a key is depressed with a certain finger, the depressed finger is changed to another finger while the depressed state is maintained. Examples of finger penetration and the like are also supplemented in FIG.

  Steps 1-1 and 1-2 in FIG. 4 constitute Step 1, and Steps 1-1 and 1-2 are subsections 1 and 2 of Step 1 of the first edited music guide data D1 (FIG. 6). Corresponding to In step 1, the fifth note “Mi” is included in both step 1-1 and step 1-2. Thus, the subdivision of the first edited music guide data D1 may be configured so that the same note is included in two adjacent steps.

  Step 2-1 and Step 2-2 constitute Step 2, and Steps 2-1 and 2-2 correspond to the subsections 1 and 2 of Step 2 of the first edited music piece guide data D1. Here, the note group z1 between step 2-1 and step 2-2 is omitted in the first edited music guide data D1. Similarly, the note groups z2 to z8 are omitted, and the steps are connected in time series to generate the first edited music guide data D1.

  Thus, when editing the first edited music guide data D1 from the original music guide data D3, phrases containing the same or similar note arrangement in the original music guide data D3 are omitted, and before and after the omitted phrases Are connected in time series.

  Note that at least one of phrases including the same or similar note arrangement may be omitted. Alternatively, the omitted phrases may be limited to phrases including the same note arrangement. It is not essential to omit the phrase.

  Further, in the generation of the first edited music guide data D1 based on the original music guide data D3, the note length conversion and the tempo value by the even expansion ratio R are performed in the same manner as the generation of the second edited music guide data D2. Changes have been made. In the first edited music guide data D1, the last note of each step or the last note of the small section may be extended longer than the expansion by the expansion ratio R. Note that note length conversion and tempo value change are not essential as long as performance guidance is performed for each category.

  The first guide process using the first edited song guide data D1 is a section-by-section guide process for performing performance guidance for each section (step by step) in time series order. A corresponding portion of the first edited music guide data D1 is used as a performance guide for each step to be practiced.

  FIG. 7 shows a part of Step 1 of the first edited music guide data D1 corresponding to the practice target music (FIG. 4) as a score. Since the configuration of each step is basically the same, step 1 will be described as a representative with reference to FIG.

  As shown in FIG. 7, the first edited music guide data D1 further includes, as event data, demo performance data (corresponding to the note group DM) and fingering range display data (note group h1, h2). Corresponding), correct answer notification data (corresponding to note groups j1, j2, etc.) are also included. In addition, data for metronome sound (not shown in FIG. 7) is also included. The metronome sound data is data for generating a metronome sound based on the time signature and tempo value in the first edited music guide data D1. This metronome sound is generated at the timing of all rests from the first to the fourth from the left in the middle of FIG.

  First, the demo performance data (DM) is data for automatically replaying the notes at each step as the practice target immediately after the start of the first guide process. The fingering range display data (h1, h2) is data for teaching the key K corresponding to two pitches indicating the fingering range in each step by light emission. Here, the fingering range indicates the interval (spread) between fingers that should be held during the performance of the step. For example, two pitches indicating the fingering range include the lowest tone and the highest tone. At least one of them is included.

  For example, in step 1, it is appropriate to maintain a finger spread of 4 degrees. Therefore, the note group h1 corresponds to step 1-1 (subdivision 1), and two pitches of the highest note (mi) and “shi” that is four degrees lower than that are set as the fingering range. In addition, note group h2 corresponds to step 1-2 (subdivision 2), and two pitches of the lowest note (la) and “re” four degrees higher than that are set as fingering ranges. Note that the two pitches that define the fingering range in each step may be uniformly the lowest and highest sounds in the practice target section.

  By the way, teaching of a finger (key pressing finger) to be used for key pressing is performed by, for example, screen display. For example, in conjunction with the performance guide, the display device 9 displays a picture of a keyboard and fingers as illustrated in FIG. Note that the keying finger instruction method is not limited to this, and for example, a finger number may be given to each note of the score displayed on the screen.

  In addition, the correct answer notification data (j1, j2, etc.) is stored in the performance guide for the practice target category (steps) according to the guides separately from the sound of each key press when the keys are pressed according to the guides. This is data for generating a notification sound for notifying that a key has been pressed. There are data (j1) and data (j2) corresponding to each of step 1-1 (small section 1) and step 1-2 (small section 2). In addition, as shown in FIG. 3 (not shown in FIG. 7), correct notification data (gj1) corresponding to each of step 1-1 (small section 1) and step 1-2 (small section 2). , Gj2). There is correct notification data (gj0) for practicing through step 1 (subdivisions 1 and 2) from the beginning to the end.

  Here, the notification sound may be different from the musical sound generated by each key depression, and the content of the sound is not limited. For example, the notification sound is an assistant (obligard) corresponding to the current practice target (step or subsection) and the next practice target (step or subsection). The notification sound is preferably a musical sound that connects adjacent steps (or small sections) musically without any sense of incongruity, and may be in any form such as a single tone, a chord, a melody, or an accompaniment. If the notification sound is an assistant or the like, it is possible to practice each category while maintaining the awareness of the association between the categories.

  Next, mainly with reference to FIG. 3 and FIG. 7, the performance practice of step 1 by the first guide process will be described. The first guide process will also be described with reference to FIG. The guide process is controlled by the CPU 5.

  When the first mode is selected as the guide mode, the first guide process is started. First, the demonstration performance of Step 1 is performed. In FIG. 7, the note group DM is reproduced by the data for demonstration performance. Next, a metronome sound (m1) based on the time signature (four quarters) and the tempo value (200) in the first edited music guide data D1 is generated. Next, the fingering range of step 1-1 (subdivision 1) is displayed according to the fingering range display data (h1). Specifically, two pitch keys K indicating the fingering range are emitted. At the same time, an instruction is given by displaying the key pressing finger. The performer presses the lighted key K. If the correct key K is pressed, a notification sound is generated from the correct notification data (j1).

  Next, a metronome sound (m2) based on the time signature and tempo value in the first edited music guide data D1 is generated. Next, the fingering range in step 1-2 (subdivision 2) is displayed according to the fingering range display data (h2). Specifically, two pitch keys K indicating the fingering range are emitted. At the same time, the key pressing finger is instructed. The performer presses the lighted key K. If the correct key K is pressed, a notification sound is generated from the correct notification data (j2).

  Next, a metronome sound (gm1) based on the time signature and tempo value in the first edited music guide data D1 is generated. Next, a performance guide by key emission in step 1-1 (subdivision 1) is executed according to data (not shown in FIG. 7) of the corresponding part of the first edited music guide data D1. If the correct key K is pressed, a notification sound is generated from the correct notification data (gj1). The subsequent performance guides are the same as in the prior art, and each time a correct key is pressed, the key to be pressed next is emitted.

  Next, a metronome sound (gm2) based on the time signature and tempo value in the first edited music guide data D1 is generated. Next, a performance guide by key emission in step 1-2 (subdivision 2) is executed according to data (not shown in FIG. 7) corresponding to the first edited music guide data D1. If the correct key K is pressed, a notification sound is generated from the correct notification data (gj2).

  Next, a metronome sound (gm0) based on the time signature and tempo value in the first edited music guide data D1 is generated. Next, a performance guide by key emission in step 1 (subdivisions 1 and 2) is executed according to data (not shown in FIG. 7) corresponding to the first edited music piece guide data D1. If the correct key K is pressed, a notification sound is generated from the correct notification data (gj0).

  When the practice by the performance guide in step 1 is completed in this way, the practice target moves to the next step 2. When the practice is completed up to the final step N, the practice by the first guide process of the current song to be practiced is finished.

  FIG. 9 is a flowchart of the learning menu process. This process is started when the musical instrument is turned on and is executed by the CPU 5, but may be started when a predetermined operator (for example, a learning mode selection switch on a panel (not shown)) is turned on.

  First, initial setting is executed (step S101). That is, execution of a predetermined program is started and initial values are set in various registers. Next, in steps S102 to S104, the process branches depending on which of the menu switches 21, 22, and 23 is turned on. When the menu switch 21 (playing SW) is turned on, the process proceeds from step S102 to step S105. In step S105, normal performance processing is executed, and a musical tone corresponding to the key pressing / release operation is generated. Thereafter, the process returns to step S102.

  If the menu switch 22 (listening SW) is turned on as a result of the determination in step S103, the process proceeds to step S106. In this case, the learning content is a mode for listening to a sample performance of the music. In step S106, the genre of the song to be listened to and the playback song in the genre are selected, and the playback process is executed. Thereafter, the process returns to step S102.

  As a result of the determination in step S104, when the menu switch 23 (used SW) is turned on, the process proceeds to step S107. In step S107, the instruction from the user is received, and the music to be practiced is selected and the guide mode is set. The guide mode includes first, second, and third modes.

  In step S108, the process branches depending on the set guide mode. One of the guide data D1, D2, and D3 is read according to the guide mode. If the set guide mode is the first mode, the first guide process (section-specific guide process) using the first edited song guide data D1 described above is executed for the song to be practiced (step S109) ( This will also be described with reference to FIG. If the set guide mode is the second mode, the second guide process using the second edited music guide data D2 described above is executed (step S110). If the set guide mode is the third mode, the third guide process using the above-described original music guide data D3 is executed (step S111). After the processes of steps S109, S110, and S111, the process returns to step S102.

  FIG. 10 is a flowchart of the first guide process (division-specific guide process) executed in step S109 of FIG. This process will be described with occasional reference to FIG.

  First, in step S201, a demonstration performance (DM) of the current practice step is executed, and in step S202, a metronome sound (m1 or m2) based on the time signature and tempo value in the first edited music guide data D1 is generated. Next, in step S203, the fingering range of the current small section of the current practice step is displayed by key emission (h1 or h2). In step S104, it is determined whether or not manual key-on, that is, whether or not the user has pressed the key K, is continued until manual key-on occurs. A musical tone of K is generated (step S205).

  In step S206, it is determined whether or not the key K that has been pressed is identical with the key that is instructed as the fingering range. As a result of the determination, if the key K that has been pressed does not match the instructed key, the process returns to step S204 to retry. On the other hand, if the key K that has been pressed coincides with the instructed key, the correct key K has been pressed. In step S207, a correct notification, that is, a notification sound for notifying that the key has been pressed correctly is generated. Generated (j1 or j2).

  Next, in step S208, it is determined whether or not there is a sub-section (remaining sub-section) whose fingering range is not specified in the current practice step. If there is a remaining sub-section, the sub-section to be processed is determined. Move forward by one (step S209) and return to step S202. On the other hand, if there is no remaining small section, the process proceeds to step S210, and the processing target is returned to the first small section in the current practice step so as to shift to the performance guide.

  In step S211, a metronome sound (gm1 or gm2) is generated, and in step S212, a performance guide for the current subsection by key emission is executed. In step S213, it is determined whether or not manual key-on, that is, whether or not the user has pressed the key K, is continued until manual key-on is detected. A musical tone of K is generated (step S214).

  Then, in step S215, it is determined whether or not the key K that has been pressed is matched with a key that is instructed by light emission as a performance guide. As a result of the determination, if the key K that has been pressed does not match the instructed key, the process returns to step S213 to perform the operation again. On the other hand, if the key K that has been pressed coincides with the instructed key, the correct key K has been pressed. In step S216, a correct notification, that is, a notification sound for notifying that the key is correct is issued. Generated (gj1 or gj2).

  Next, in step S217, it is determined whether or not there is a small section (remaining small section) for which the performance guide has not been performed in the current practice step. If there is a remaining small section, one small section to be processed is determined. Proceed (step S218), and return to step S211. On the other hand, if there is no remaining small category, the process proceeds to step S219.

  In step S219, a performance guide is executed through the entire practice step from the beginning to the end. At that time, a metronome sound (gm0) is generated at the start of the performance guide. If a key that matches the key instructed in the performance guide is made, a notification sound is generated to notify that the key is correct (gj0).

  Next, in step S220, it is determined whether or not there is a next practice step that has not been practiced in the first edited music guide data D1. As a result of the determination, if there is a next practice step, the practice step to be processed is advanced by one (step S221), and the process returns to step S201. If there is no next practice step, the process of FIG. finish.

  An example in which the original music guide data D3 is divided at a place where finger penetration or the like occurs when the first edited music guide data D1 is edited will be described by exemplifying other music.

  FIG. 11 is a diagram illustrating a score example of another practice target song. This score is part of Mozart's Turkish March. In the musical score of FIG. 11, the number of the finger to be used for key depression is attached in the vicinity of each note. As for the finger numbers, 1, 2, 3, 4, and 5 indicate the thumb, index finger, middle finger, ring finger, and little finger, respectively.

  As shown in FIG. 11, at the point f1, when playing a sound string descending from “mi” to “le”, the finger to be used is shifted from the thumb to the index finger, so that the finger is over the finger. Similarly, the points f2, f3, and f9 are over the finger. In addition, at the point f4, when playing a sound string that rises from “So #” to “La”, the finger to be used is shifted from the index finger to the thumb, so that the finger is dropped. Similarly, finger insertion is also performed at locations f5 to f8. In addition, at the location f10, when the key “d” having the same pitch is continuously pressed, the finger to be used is switched from the index finger to the middle finger, so that the finger is changed.

  As described above, according to the present embodiment, performance guidance is performed in chronological order for each segment (practice step) in which music is divided at locations where finger penetration or the like occurs. Prior to the start of the performance guide for the small section of the practice step, the keys corresponding to the two pitches indicating the fingering range (h1, h2) in the small section are taught. As a result, it is possible to learn how to maintain an appropriate finger interval in a performance unit without finger penetration or the like. In addition, music can be acquired step by step by concentrating on each category. It is not essential to divide the practice steps into a plurality of subdivisions.

  Also, when editing the first edited music guide data D1, phrases containing the same or similar note arrangement in the original music guide data D3 are omitted, so repeated practice of similar phrases is omitted and performance is performed. Can efficiently learn multiple types of practice elements appearing in.

  Further, according to the present embodiment, when a key is pressed according to the guide in the performance guide for each practice step (or sub-section), the key is pressed according to the guide separately from the musical sound generated by each key press. A notification sound (j1, j2, gj1, gj2) for notifying that is generated. Thereby, the achievement achievement of acquisition can be given for every division and a music can be acquired in steps. Moreover, since the practice target is shifted to the next practice step (or sub-category) after the notification sound is generated, the learning notification for each category can be clarified. Concentration is easy to continue.

  Also according to the present embodiment, the first edited music guide data D1 and the second edited music guide data D2 correspond to those obtained by expanding the notes in the original music guide data D3 at an even expansion ratio R, The tempo value is smaller than the multiplication value of the tempo value and the expansion ratio R in the original music guide data D3. Thereby, it is possible to practice with the performance guide at an actual time with an even time signature and slower than the original music regardless of the time of the original music. In particular, by setting the expansion ratio R to such a value that the note with the shortest note length in the original song guide data D3 is converted into a quarter note in the second edited song guide data D2, the familiar four time signature is obtained. Practice with a performance guide. Beginners can get into practice smoothly when practicing odd-numbered beats.

  In the present embodiment, for each song to be learned or practiced, data D0 to D3 corresponding to each song is stored in advance in the ROM 6 or the external storage device 10 and read out to the RAM 7 when used. However, the data D1 to D3 may be detected and generated from the original music performance data D0 by a detection program (not shown). In that case, an instruction such as finger penetration may be given by “range teaching means” using the detected data D1 to D3.

  It should be noted that a similar effect may be obtained by reading a storage medium storing a control program represented by software for achieving the present invention to the present instrument, in which case the data is read from the storage medium. The program code itself realizes the new function of the present invention, and the storage medium storing the program code constitutes the present invention. Further, the program code may be supplied via a transmission medium (for example, the communication I / F 12), and in that case, the program code itself constitutes the present invention. As a storage medium in these cases, a floppy disk, a hard disk, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a magnetic tape, a nonvolatile memory card, and the like can be used in addition to a ROM.

  Although the present invention has been described in detail based on preferred embodiments thereof, the present invention is not limited to these specific embodiments, and various forms within the scope of the present invention are also included in the present invention. included.
