Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a musical instrument practice support device and a recording medium for musical instrument practice information used therein.
In particular, the present invention relates to a technique for playing a typical instrumental performance and accompaniment for a measure while displaying a musical score of a measure to be practiced in order to support practice of musical instrument performance for a predetermined music piece.

[0002]

2. Description of the Related Art It is very important for a musical instrument player, both professional and amateur, to practice individually.
In the case of performers belonging to a band or orchestra, it is necessary for members to meet together and practice ensemble, but individual performers also play only their assigned parts with their own instruments. You also need to practice individually. Especially,
For amateur performers, personal practice, modeled after professional performance, is the first step in progress.

[0003] In the case of individual practice of musical instruments, usually, a method of obtaining books and musical scores related to music and actually playing the musical instruments while watching them is adopted. However, when practicing while looking at such books and music scores, the information to be used as a model is limited to visual information, so it is necessary to recognize whether the balance with the accompaniment, the tempo, the pitch, etc. are appropriate. Is difficult to do.

In order to make up for these drawbacks, software for supporting musical instrument practice using media such as general audio CDs, cassette tapes and video tapes has become widespread. Individual training is performed with support software. Such practice support software includes, for example, performances by a professional musician and backing accompaniment. You can practice playing.

[0005]

If the practice is performed by using the above-mentioned practice support software together with a musical score, it is possible to practice a musical instrument with reference to both visual and auditory information.
However, conventional practice support software cannot freely change the tempo (speed) or key (pitch) of the performance. It is very important for a trainee to be able to practice by setting the tempo and key of the performance freely. Usually, when practicing a musical instrument, a process is often performed in which, at first, a performance is performed at a slow tempo, and when the player becomes accustomed to a certain degree, the performance is gradually performed at a higher speed. Further, since the keys of a wind instrument such as a trumpet or a saxophone are different from those of a stringed instrument such as a piano or a guitar, it is necessary to change the key of the accompaniment according to the instrument to be practiced.

On the other hand, in practicing musical instruments, it is often necessary to repeatedly practice only a specific portion (measure). However, conventional practice support software that uses media such as audio CDs, cassette tapes, and video tapes is based on the premise that sequential information is provided. It is very difficult to take.

With the rapid spread of personal computers in recent years, a large number of software of a genre called a so-called DTM (Desk Top Music) has been provided, but these DTM software support a music composition operation using a computer. It is not software for supporting musical instrument practice. For this reason,
Even if the practice of playing a musical instrument is performed using this DTM software, sufficient operability cannot be obtained.

Accordingly, an object of the present invention is to provide a musical instrument practice support device having sufficient operability suitable for musical instrument performance practice, and to provide musical instrument practice information for use in such a support device. The purpose of the present invention is to provide a recording medium.

In the embodiment shown here, a display device for a general-purpose personal computer is used as the score display unit 10. Used. The musical instrument sound reproducing unit 20 is a device for reproducing a musical instrument sound based on a reproduction control signal given from the reproduction control unit 60. In the embodiment shown here, MIDI (Musical Instrument) is used as a reproduction control signal.
nt Digital Interface) data signal, especially SMF (St
Andard MIDI File) format data signals are used, and the musical instrument sound reproducing unit 20 uses a MIDI sound source and a speaker for a general-purpose personal computer.

On the other hand, the data reading section 30 is a device having a function of reading practice support data from a dedicated recording medium M. The read practice support data is stored in the display control unit 50.
And the reproduction control unit 60.
In this embodiment, a CD-ROM is used as the recording medium M, and the data reading unit 30 is constituted by a CD-ROM drive for a general-purpose personal computer. Of course, the recording medium M is a CD-ROM
Alternatively, a DVD-ROM, a magnetic recording medium, a magneto-optical recording medium, or the like may be used. This recording medium M corresponds to the recording medium for musical instrument practice information according to the present invention.

The operation input unit 40 is a device having a function of specifying a measure of a musical piece to be practiced as a measure to be practiced based on an instruction of an operator (musical instrument practicer). In the present embodiment, various operation inputs such as designation of a tempo (speed) and a key (pitch) for reproducing a measure to be practiced, designation of a type of a musical score to be displayed, and a control command for a reproduction state of a musical instrument sound, etc. It also has a function to input information. Display control unit 50
Extracts the necessary data from the practice support data read by the data reading unit 30 with respect to the bar to be practiced specified by the operation input unit 40, and generates a display control signal for displaying a predetermined score. Is given to the musical score display unit 10. Further, the reproduction control unit 60 extracts necessary data from the practice support data read by the data reading unit 30 with respect to the bar to be practiced specified by the operation input unit 40, and reproduces the predetermined instrument sound. A process of generating a control signal and providing the control signal to the musical instrument sound reproducing unit 20 is performed.

One of the features of the present invention resides in a specific format of the practice support data recorded in the recording medium M. As shown in the lower part of FIG. 1, the practice support data F10 recorded in the recording medium M includes a MIDI data file F11, a score image data file F12,
The control data file F13 is composed of three files. The MIDI data file F11 is a file containing MIDI data relating to the music to be practiced.
, A predetermined music is reproduced with a predetermined musical instrument sound.

The musical score image data file F12 is a file containing musical score image data indicating the musical score of each bar of the music. In this embodiment, the score image data indicating the score of one bar is defined as one file, and the score image data file F12 forms a large number of files. The illustrated example is an example of the training support data F10 for the music piece composed of the first to nth measures. The score image data file F12 contains, for example, the score image data of the first measure as the file PIC1. The file PIC2 contains the score image data of the second bar, and the file PICn contains the score image data of the nth bar. When a plurality of bars have the same score image, the same score image data can be shared. For example, when the arrangement of notes in the third bar and the fifth bar is the same, the same score image data may be shared by the third bar and the fifth bar.

The control data file F13 has a file number n in the score image data file F12, in other words, M
It is a file composed of a total of n records of records R1 to Rn corresponding to the number of measures n of the music recorded in the IDI data file F11. The n records include the first measure to the nth measure. Are recorded in association with each other. More specifically, as shown in the drawing, each record records a belonging page designation code, a MIDI data designation code, a score image data designation code, and a display position designation code. The affiliation page designation code is a code for designating the affiliation page of the bar on the score, the MIDI data designation code is a code for designating the corresponding part of the MIDI data for the bar, and the score image data designation code is The display position designating code is a code for designating the musical score image data for the bar, and the display position designating code is a code for designating the musical score display position for the measure.

FIG. 2 is a block diagram showing the configuration of the training support data F10 in more detail. As mentioned above, MID
In the I data file F11, MIDI data for a predetermined tune is recorded. For example, the hatched portion shown in the figure is the MI bar
9 shows DI data. Further, the score image data file F12 contains score image data indicating the score of each bar of the music in one bar per file.
For example, the illustrated file PIC1 contains image data representing the musical score of the first bar, and the file PIC2 contains image data representing the musical score of the second bar. In this embodiment, the score image data is
It is prepared as bitmap image data for each bar. Such bitmap image data has a relatively large data capacity, but is convenient because musical notes and arbitrary music symbols can be arranged at arbitrary positions. If bitmap format image data is used, image data can be prepared by simply reading the existing musical score printed on a paper medium with a scanner device as it is. Support data can be created at very low cost.

On the other hand, the control data file F13 functions to centrally manage control codes for each bar.
For example, each code in the first record R1 indicates a control code for the first measure. Specifically, for example, the MIDI data designation code in the record R1 is the first code in the MIDI data file F11. This code indicates the start position and the end position of the MIDI data relating to the bar (the start position and the end position of the hatched portion in the figure). The musical score image data designating code in the record R1 is the first musical score image data file F12.
This code is used to specify the musical score image data of a bar.
For example, it is a code indicating a musical score file name “PIC1”. Further, the belonging page designation code in the record R1 is a code indicating to which page of the entire score the score of the first bar indicated by the score file name “PIC1” belongs. The position designation code is a code indicating which position in the page to which the position should be displayed.

FIG. 3 is a table showing a specific example of the control data file F13. The control data file F13 shown here is composed of a total of n sets of records R1 to Rn, and information of one record is described in one line in the table shown. Each record is
Each contains a control code for one bar. That is, "measure number" is a serial number assigned to each measure, and "page" is information that functions as a belonging page designation code indicating a page to which the musical score of the measure belongs. The “MIDI data start position” indicates the start position (specifically, the number of bytes from the beginning of the data) of the MIDI data corresponding to the measure in the data in the MIDI data file F11, and the “MIDI data end position”. "Position" indicates the end position (similarly, the number of bytes from the beginning of the data) of the MIDI data corresponding to the measure, and is information that functions as a MIDI data designation code. Further, “score file name” indicates the file name of the image data file corresponding to the bar contained in the score image data file F12, and is information that functions as a score image data designation code, and “X coordinate”. And “Y coordinate” indicate position coordinates (in this example, XY coordinate values on the display screen to which the upper left corner of the score image for one measure is to be assigned) for displaying the score of the measure, and Information that works.

FIG. 4 is a diagram showing a state where the first page of the score is displayed on the display screen of the score display section 10 based on the control data file F13 as shown in FIG. In this embodiment, the display screen of the score display unit 10 is:
Upper operation area 70, main display area 80, lower operation area 90
And the score on the first page is
It is displayed in the main display area 80. That is, in the title display section 81 provided on the first line of the main display area 80,
The title of this song is displayed, and the scores from the first bar to the sixth bar are displayed in the score display section 82 in the center. Further, on the reproduction operation unit 83, various operation buttons for performing a reproduction operation are displayed.

The control data file F1 as shown in FIG.
When 3 was prepared, the operator (practice)
For example, when three measures from the second measure to the fourth measure are specified as measures to be practiced, the display control unit 50 causes the display control unit 50 shown in FIG.
Will be obtained as shown in the musical score display section 82. The process is as follows. First,
Records R2 and R describing control codes for measures 2 to 4 specified as measures to be practiced
3 and R4, the page to which the user belongs is recognized. In the example shown in FIG. 3, all of the second to fourth measures have the belonging page of 1
This is the page number. Therefore, a process is executed in which the first to sixth measures belonging to the same first page are selected as display-measure bars, and these display-target bars are displayed on the screen as the score of the first page. For example, with respect to the first measure, referring to the record R1 describing the control code of the first measure, the image having the score file name “PIC1” is represented by X
Since it is indicated that it should be assigned to the position of the Y coordinate value “50, 50”, the score image data file F1 shown in FIG.
2, a process of allocating the bitmap image data having the file name “PIC1” stored in 2 so that the upper left corner thereof is located at the coordinate position of “50, 50” on the display screen. The same processing is performed from the second bar
If the sixth bar is also executed, the score display unit 82 of FIG.
Is obtained as shown in FIG.

[0029]§2. Operation input by operator  In this embodiment, operation input from the operator can be performed.
Some on the screen so that you can
Operation buttons and input boxes are provided.
0 indicates an operation button or input provided on the display screen.
Operator operation on the box (specifically,
For example, monitoring with a mouse pointer)
Recognize what kind of operation input is given from the
And In the configuration shown in FIG.
To operate buttons and boxes on the screen,
The operation input information shown is transmitted from the operation input unit 40 to the display control unit 50.
And to the playback control unit 60 to update the display contents.
A new display control signal for
Playback control for playing MIDI data for a clause
Or a signal will be generated.

Hereinafter, the functions of these operation buttons will be described with reference to the display screen of FIG. First, the playback operation unit 83 provided at the lower left of the main display area 80 is composed of a group of buttons for performing various playback operations. In order from the left, a jump button to the beginning (from the first bar to be practiced) Playback), jump to previous measure button (playback from the bar immediately before the currently playing measure), stop button (stop playback), play button (start playback), go to next measure Jump button (repeated from the bar after the currently playing bar), repeat button (when the last bar to be practiced is reached, set the repeat mode to repeat the performance by returning to the first bar to be practiced again ). The operator operates the reproduction operation unit 8
By operating the button No. 3, the musical instrument sound can be reproduced for an arbitrary bar in the bar specified as the bar to be practiced.

On the other hand, in the upper operation area 70, input boxes 71 to 76 and operation buttons 77 are provided.
The input box 71 is a box for inputting a numerical value (a numerical value 100 in the illustrated example indicates a speed at which a quarter note is played 100 times per minute) for specifying a tempo when the MIDI data is reproduced. Reference numeral 72 denotes a box for inputting a numerical value designating a key height when MIDI data is reproduced (the numerical value +1 in the illustrated example indicates a pitch that is a semitone higher than the standard key). Although numerical values can be directly input to these boxes from a keyboard, they can also be input by operating the up and down arrows provided on the right side of the boxes with a mouse.

The input box 73 has a melody ON /
In the box for specifying OFF switching, if you check the X mark by mouse operation and turn it ON, the melody (melody to be played by the trainee himself) will be played along with the accompaniment, and the X mark will be turned off by turning off the check mark When in the state,
Only the accompaniment will be played. For example, at the beginning of the practice, the melody can be practiced with the melody turned ON, and when the melody is improved to some extent, the melody can be practiced while listening to the accompaniment only with the melody turned OFF. The input box 74 is a box for designating ON / OFF switching of the count at the start of the reproduction. When the X mark is checked with the mouse operation to turn the count ON, when the reproduction is started, a count sound “click” is generated. It will be presented four times. The practitioner can play the musical instrument in accordance with the count sound so that the start of the music can be adjusted well.

On the other hand, an input box 75 is a box for inputting a measure for starting practice, and an input box 76 is provided.
Is a box for inputting a measure for ending the practice.
For example, as in the example shown, the box 75 contains the number 2,
When a numerical value 4 is input in the box 76 (this input operation is also
This can be done directly from the keyboard or by operating the up and down arrows provided on the right side of the box with a mouse), and the second to fourth measures are designated as measures to be practiced. The playback operation by the playback operation unit 83 described above is valid for the measure to be practiced specified here. For example, when the second bar to the fourth bar are designated as the bars to be practiced, the repeat mode is set in the reproduction operation unit 83, and when the operation button for starting the reproduction is clicked with the mouse, the second bar to the bar to be practiced are set. The fourth measure will be reproduced repeatedly.

After all, in the configuration shown in FIG. 1, the display control unit 50 recognizes the page to which the bar to be practiced specified by the operation input unit 40 belongs with reference to the control data file F13 as shown in FIG. Then, a measure belonging to the same page as the belonging page is selected as a measure to be displayed, and a process of generating a display control signal for displaying a musical score corresponding to the measure to be displayed at a predetermined display position is executed. . In the case of the above example, the second bar to the fourth bar are designated as the bars to be practiced, but the first bar to the sixth bar belonging to the same page as these are selected as the bars to be displayed,
It will be displayed as shown in FIG. Further, the reproduction control unit 60 refers to the control data file F13, recognizes the address of the MIDI data corresponding to the measure to be practiced, and responds to the predetermined measure based on the operation input information given from the operation input unit 40. A process of generating a reproduction signal for reproducing the MIDI data portion thus performed is executed.

It should be noted that the reproduction control unit 60 switches the display control unit 50
Is provided with playback information indicating the measure currently being played back, so that when the page to which the practice target measure belongs extends over a plurality of pages, the display control unit 50 always displays the information about the page to which the currently playing measure belongs. The display control signal can be switched so that the score is displayed.
For example, the operator enters the number 2,
Suppose that the user inputs a numerical value 9 in the input box 76 and specifies the second to ninth measures as the measures to be practiced. Referring to the control data file F13 in FIG. 3, the second to sixth measures belong to the first page, whereas the seventh to ninth measures belong to the second page. Therefore, 1
All measures belonging to page 2 are to be selected as measures to be displayed.
One of the pages is switched and displayed. Specifically, the score of the first page is displayed during the playback of the bar belonging to the first page, and the score of the second page is displayed during the playback of the bar belonging to the second page. become.

In this embodiment, in the initial state at the time of startup,
The default setting is that all measures are to be the measures to be practiced. Therefore, when the operator has not specified any measure to be practiced, the numerical value of the input box 75 is 1 and the numerical value of the input box 76 is n.
(The number of all measures is n), from the first measure to the n-th measure
All measures up to the measure are set as measures to be practiced. In this state, if the playback is performed by operating the playback operation unit 83, the first bar to the nth bar are played back in order, and the score display unit 82 always displays the score of the page to which the currently playing bar belongs. Is automatically turned so that is displayed.

When the operator inputs predetermined numerical values into the input boxes 75 and 76, as described above, only a specific measure is designated as a measure to be practiced. Will work for this measure, but this can easily be changed back to the default. That is, the operation button 77 provided on the upper right of the display screen is a button for returning the measure to be practiced to the default designation. When this operation button 77 is operated, all measures from the first measure to the nth measure are set as the practice measure. Returns to the initial state of the default setting of measures.

On the other hand, the operation buttons in the lower operation area 90 have the following functions. First, the operation button 91 is a button for terminating the operation of the support device. As will be described later, the device of the present embodiment is a device configured by incorporating dedicated application software into a general-purpose personal computer. By operating the operation button 91, the dedicated application software is terminated. can do. The operation button 92 is a button for shifting to the menu mode of the support device. In the present embodiment, the recording medium M supplied as a CD-ROM contains practice support data for a plurality of music pieces. In the menu mode, a list of the plurality of songs is displayed, so that the trainee can specify an arbitrary song. “EX” shown in the title display section 81 of FIG.
The title "-1" indicates that the music title "EX-1" was selected in this menu mode. The operation button 93 is a button for displaying a page before the score page currently displayed on the score display section 82, and the operation button 94 is a button for displaying the score display section 82.
Is a button for displaying the next page of the musical score page currently displayed on the screen. These buttons function only when playback of the instrument sound is stopped. When the reproduction of the musical instrument sound is started, the page to which the bar being reproduced currently belongs is always displayed on the musical score display section 82, as described above.

Only one of the operation buttons 95, 96 and 97 is activated (indicated by a black circle), and is used to select the type of musical score to be displayed. In the example shown here, the musical score is composed of an upper melody score and a lower tablature score. A melody score is a so-called ordinary music score that shows the melody itself on a staff notation, while a tablature generally indicates the position of a finger with respect to each string when playing a stringed instrument such as a guitar.
This is a musical score shown on a six-line score. In the present embodiment, one of the display of only the melody notation (operation button 95), the display of only the tab notation (operation button 96), and the display of both the melody notation and the tab notation (operation button 97: illustrated state) is displayed. ,
It can be specified by operating each operation button. In order to allow the user to select the type of score to be displayed from the three types, for example,
Prepare three types of score image data files and use them as appropriate. Alternatively, separate a score image data file with melody score only and a score image data file with tab score only separately, and if necessary, Although some contrivance such as combining and using these is necessary, the description of these specific methods is omitted here.

§3. Additional Functions So far, the instrument training support apparatus according to the present invention has been described with reference to the basic embodiment. However, here, there are some practical additional functions that can be applied to this basic embodiment. I will tell you.

(1) Highlighting of bars to be practiced As described above, in the present embodiment, in the default setting of the initial state, all bars are designated as the bars to be practiced. By designating only a measure as a measure to be practiced, it is possible to focus on practicing only this particular measure. In this case, it is preferable that the score of the specific measure specified as the measure to be practiced be highlighted on the display screen, so that the practicer can easily grasp the measure to be practiced visually. Specifically, the display control unit 50 may have a function of displaying the score of the measure to be practiced in the measures to be displayed in a manner that can be distinguished from the scores of the other measures.

FIG. 5 is a diagram showing an example in which, when the second to fourth measures are designated as measures to be practiced, these measures are highlighted on the score. In this example, the display color of the second bar to the fourth bar on the musical score is changed from the display color of the other bars to thereby highlight the bar. The operation by the reproduction operation unit 83 functions on the highlighted bar. As the highlighting, it is possible to adopt not only a method of changing the color but also a method of changing the luminance, for example. In other words, the score of the measure to be practiced is displayed in a distinguishable manner from the scores of other measures. Any method can be adopted as long as it can be performed.

(2) Index indicating the measure being reproduced As described above, the reproduction control unit 60 provides the display control unit 50 with reproduction information indicating the measure currently being reproduced. Therefore, it is also possible to add a function of displaying an index indicating the bar currently being reproduced on the score based on the reproduction information to the display control unit 50. For example, the index 84 shown in FIG. 5 indicates that the measure currently being reproduced is the second measure. When the playback portion moves to the third measure, the index 84 moves to a position indicating the third measure. In this way, indicating which measure is currently reproduced by the index 84 is convenient because it is particularly convenient for a beginner to avoid losing music.

(3) Index indicating a note being reproduced The index 84 has a function of indicating a measure being reproduced.
It is not possible to provide detailed information such as which note is sounding. Here, an effective method for displaying an index indicating a note corresponding to a currently sounding sound will be described.

As described above, in this embodiment, the image data in the musical score image data file F12 is image data in a bitmap format, and individual notes in the image data cannot be directly recognized. . However, the reproduction information provided from the reproduction control unit 60 to the display control unit 50 includes information indicating the measure currently being reproduced and information indicating the elapsed time from the start of the performance of the currently reproduced measure. Is possible. For example, during the reproduction of the second measure, it is easy to provide in real time information indicating that the currently reproduced measure is the second measure and information indicating the elapsed time from the beginning of the second measure.
Therefore, the display control unit 50 determines, based on the elapsed time,
It is possible to specify the approximate position of the currently sounding note. For example, as shown in FIG. 6, assuming that the total playing time of one measure being reproduced is T, the note Q is given at the moment when the elapsed time tQ is given in real time.
Can be recognized as being reproduced. Therefore, as shown in FIG. 7, if the index 85 is displayed at a position corresponding to the given elapsed time tQ, the note being reproduced can be indicated in real time. In the example shown in FIG. 7, a line-shaped index 85 is used, and the index 85 moves in the direction of the arrow in the figure in real time.

However, in order for the index 85 to accurately indicate the position of the note currently being reproduced, each note on the musical score for one measure prepared as musical score image data is used to start the performance of the measure. It is preferable to arrange at a position corresponding to a delay time from the time to the time of playing the note. Each note has a unique playing time, for example, a half note has twice the playing time of a quarter note. Therefore, in the bar shown in FIG. 6, the delay time from the start of the performance of this bar to the performance of the note Q changes depending on the length of the note preceding the note Q. Therefore, if the delay time until the performance of the note Q is actually started is tQ, the position of the note Q is set to (tQ / T) from the left end position of this bar. If score image data is prepared in advance, index 8
5 enables more accurate note position display.

[0047]§4. Practical product form  Finally, a practical product form for implementing the present invention is described.
Please note that. FIG. 8 shows an example of such a product form.
FIG. In this product form, score and CD-R
OM is a set. Scores are traditionally used
This is a general musical score printed on a printed paper medium. C
The D-ROM is compatible with the recording medium M in the configuration shown in FIG.
That is true. However, in this CD-ROM,
In addition to the training support data F10 described above,
Application software F20.

As described above, if the CD-ROM is provided in a form containing the application software F20 together with the training support data F10, a general-purpose personal computer system can be provided as the hardware having the configuration shown in FIG. Can be used. That is,
In the configuration shown in FIG. 1, the music score display unit 10, the musical instrument sound reproduction unit 20, and the data reading unit 30 can use hardware conventionally used as a general-purpose personal computer system without any change, and thus the present invention is unique. In order to perform the processing described above, the dedicated application software F20 may be incorporated into the general-purpose system and used. More specifically, FIG.
The portion enclosed by a dashed line as 00 is a component unique to the present invention, and a processing program for executing functions unique to these components is prepared as application software F20 in the CD-ROM. I just need. Specifically, a program for causing the respective components of the operation input unit 40, the display control unit 50, and the reproduction control unit 60 to execute the processing operations described above is prepared as the application software F20. Good.

Needless to say, it is not necessary to incorporate the practice support data F10 and the application software F20 without fail. For example, if the application software F20 is already installed in the general-purpose personal computer owned by the trainee, the trainee only needs to obtain a CD-ROM containing the training support data F10. Therefore, in commercial use of the present invention, a CD-ROM containing only the training support data F10 and the application software F2
CD-ROM containing only 0, CD- containing both
It can be provided in various forms such as a ROM. The practitioner can selectively obtain a medium suitable for his / her general-purpose personal computer from the media provided in various forms. Also, different songs can be recorded for each medium, so that the trainee can selectively obtain a medium on which the desired song is recorded.

In the music score on a paper medium, in order to save space, a repeated symbol or the like is often used to partially omit a duplicate bar or the like. on the other hand,
In practicing using the musical instrument practicing support device according to the present invention, it is preferable that the musical scores of all measures be displayed on the screen in the order of performance without performing such omission. As described above, if the bar is not omitted in the score on the screen, the correspondence between the score on the screen and the score on the paper medium may be unclear. Therefore, a measure number indicating the correspondence between each measure constituting the score on the screen and each measure constituting the score on the paper medium is added, so that the correspondence between the two is clarified. It is preferred that For example, the score on the screen shown in FIG. 9 is provided with a bar number 86 (indicated by a circle in the illustrated example), and this bar is represented by a repeat symbol in the score on a paper medium. This indicates that it corresponds to the eighth measure.
