Returning to the description of the main program in FIG.
By executing the lesson content determination object program (FIG. 5), the presence / absence of warm-up, review, and practice of playing a practice song, and the content of the lesson scheduled for the current time, which includes these practice times, are determined in consideration of the user's request. As a result, the performance practice taking into account the user's wishes is performed.

Then, at step 108, the practice time for warming up, reviewing, and practicing the practice music are sequentially taken out from the determined lesson schedule, and the lesson object program (FIG. 6) is executed at step 110 according to the schedule. By performing, the warm-up, the review, and the practice of playing the practice music are sequentially performed. In the practice practice of the practice music, after allocating the time for the music reading practice and the metronome step practice, the practice music is divided into bars, phrases, and the like, and a plurality of practice parts obtained by the division are sequentially displayed on the display 15. The practice and the metronome step practice are performed according to the practice plan prepared above. The practice of reading music is expected to put emphasis on notation reading and ensure that the correct key is pressed on the keyboard, and the practice of metronome step exercises is to put weight on the key pressing timing and the correct key is pressed at the correct timing That is what you expect.

The results of the performance practice are evaluated and scored in accordance with a predetermined standard. The evaluation and the score are performed for each of the plurality of practice parts and for the entire practice music. If not, the progress of the practice is controlled according to the scoring result, such as the sequential display of the plurality of practice parts and the stop of the practice according to the practice plan. Thus, the progress of the practice is determined in accordance with the degree of performance learning by the user, so that the user can reliably and efficiently practice the musical instrument performance. During the performance practice, the practice time is managed by executing the timer object program (FIG. 8). Regardless of the end of the performance practice, it is moved to the next exercise. As a result, the performance practice is not interrupted unnecessarily on the way for the time management, and the performance practice is efficiently performed without remaining in one practice task.

When all of the warming-up, review, and practice of the practice music as described above are completed, the computer determines in step 112 that the lesson is over, and in step 114 executes the lesson object program (FIG. 6). Perform the end process of the lesson. In the termination processing, data such as the evaluation and scoring results, the time required for the practice, and the like are added to the practice plan data, and the user model representing the user level is modified according to the current practice result. As a result, the progress of the user's performance can be accurately determined, and the user level can be used appropriately for future practice. Then, in step 116, the execution of this program ends.

On the other hand, during the diagnosis and practice as described above, the timer object program (FIG. 8) and the charging object program (FIG. 9) are executed in parallel.
The user is charged a fee according to the usage time of the computer device. This fee also differs depending on the contents of the diagnosis and the practice. Thereby, an appropriate fee for using the music education system can be collected from the user.

Upon completion of the processing in step 224,
Since the activation object 200 has completed all the processes related to the user inquiry message, the activation object 200 issues a practice music selection message to itself in step 210. In response to the issuance of this message, in step 240, the activation object 200 uses the display 15 to ask the user whether he / she wants to practice the same music as the previous practice music or to practice a new music. When the practice is started for the first time, the answer to this inquiry is automatically sent to the new song.

In response to this inquiry, when the user selects a new song or starts practice for the first time, the activation object 200 executes a candidate song selection routine in step 242. This candidate song selection routine is shown in detail in FIG. 10, and the activation object 200 starts executing the routine in step 260 and proceeds to step 26
In step 1, the user selects a practice content. In this case, the activation object 200 displays on the display 15 information such as repertoire expansion, level-up of a specific technique, overall level-up, and challenge for a specific song as practice contents, and selection information from the keyboard 14 input by the user. Enter Next, in step 262, if the selected content is the selected content, the activation object 200 displays on the display 15 the specific technique of each item shown in the user model such as rhythm practice, left hand practice, and the like. Select a specific technology from the display. If the selected content is or, in step 263, a level width that can be increased by practicing one piece of music is calculated based on each data of the user model stored in the hard disk 16, in particular, the personality of the user. . Next, at step 264,
Based on the level width, a target level value is calculated for each item of the user model data and temporarily stored in the RAM 13.

At step 265, the internal database 1 is stored on the basis of the target level value for each item and the practice contents selected at steps 261 and 262.
With reference to the attribute data (FIG. 18) in the music data in FIG. The music data is retrieved from the database 17. Next, the song title of the candidate song searched in step 266 is displayed on the display 15, and the user is made to select the song using the keyboard 14 in step 267. Then, in step 268, the attribute data in the song data corresponding to the selected song name is read from the internal database 17, and in step 269, the target level of each item of the calculated user model and the attribute level of each item in the attribute data are calculated. The items having a large level difference are displayed by comparing with the required level.
Then, in step 270, the time required to clear the target level is calculated according to a predetermined reference in accordance with the level difference for each item, and in step 271 the same time is displayed on the display 15 as the estimated practice time. indicate.

Then, in step 272, an inquiry is made to the user as to whether or not to approve the selected music using the display 15. In response to this inquiry, if the user inputs an approval using the keyboard 14, the execution of the candidate music selection routine is terminated in step 273. On the other hand, if the user does not approve the inquiry, a plurality of candidate songs are displayed on the display 15 in step 266, and the process of steps 267 to 272 again determines the selected song.

After the execution of the candidate music selection routine, the activation object 200 reads out all the music data related to the selected music from the internal database 17 and writes it in the RAM 13 and the hard disk 16 in step 244. Then, in step 246, a training plan is created on the RAM 13. In creating this practice plan,
Based on the calculated level difference between the items, as shown in FIG. 17, the items to be practiced by the user are determined from among a large number of practice items prepared in advance, and the scheduled practice time for each item. Is calculated. However, in the table of FIG. 17, the implementation date, the success rate, the recognition of the termination, and the consumption time are left blank.

Next, in step 248, the prepared training plan is displayed on the display 15, and in step 250, the display 15 is used to inquire of the user's request for the training plan. Then, in step 252, if there is a request, the training plan is modified according to the request, and if not, the program proceeds to step 254. In step 254, the exercise plan is stored as exercise plan data in a location corresponding to the user name in the user information storage area on the hard disk 16.

On the other hand, if the music being practiced is selected in step 240, the process of step 256 is executed.
In step 256, the practice music data in the user information corresponding to the user name input in step 218 is read from the hard disk 16 and

D. Diagnosis Object Next, the diagnosis object 500 (FIG. 7) specified in step 226 of the activation object 200 will be described. In this case, an activation message is issued by the processing of the step 226, and data representing the diagnosis together with this message is used as the condition data as the diagnosis object 500.
The user level data indicating the self-reported user level and the time data indicating the diagnosis time are also sent to the diagnosis object 500.

The diagnosis object 500 is stored in the step 50
After the processes of steps 2 to 506, the processes of steps 508 to 512 are executed based on the condition data. In the process of step 508, the self-designation of the diagnosis object and the issuing of an activation message using data representing the score evaluation as condition data, and the execution of the processes of steps 514 to 532, the single note reading, the double note reading, and the sound section. It performs each diagnosis of symbol reading. The process of step 510 also specifies the diagnosis object by itself and issues a start message using data representing the performance skill diagnosis as condition data to execute the processes of steps 534 to 568. Each diagnosis is performed for keying and double-tone keying. The processing of step 512 is for diagnosing the comprehension of the ideographic symbol (which constitutes a part of the reading ability). Then, each time these diagnoses are completed, the diagnostic object 500 determines in steps 570 and 57
Step 2 is executed. Steps 502 to 50
The processing of 6 is executed every time the self-designation is made for each diagnosis.

The details of each diagnosis will be described later, and steps 502 to 504, 570, and 572 will be described first. In step 502, the time given to the higher-level diagnosis item, which is represented by the time data always sent together with the activation message, is allocated to each of the lower-level diagnosis items. For example, activation object 2
If the diagnosis object 500 is specified by 00, the total time for diagnosing the user (for example, 10 minutes)
Is allocated for each predetermined time (for example, 4 minutes, 4 minutes, 2 minutes) to each diagnosis of the music reading ability, the performance skill, and the ideographic symbol understanding ability. In addition, when the activation message is issued using the reading performance diagnosis data as the condition data in the process of step 508, the time (for example, 4 minutes) allocated to the reading performance diagnosis is changed to the single note reading ability, the double note reading ability, and A predetermined time (for example, 2 minutes, 1 minute, 1 minute) is allocated for each diagnosis of clef reading ability.

In step 504, an execution program notification message is issued to charging object 700. At this time, data representing the diagnosis item is also sent to the charging object 700. As a result, the charging object 700 stores the RA in step 704 in the same manner as described above.
The unit charge data in M is set to a predetermined amount corresponding to the diagnosis. Therefore, the unit fee corresponding to the diagnosis is accumulated in the billing data every time the timer measures the predetermined time.

At step 506, the timer object 6

At step 06, the data representing the allocated time is stored, and after the lapse of the same time, a process termination request message is issued to the object that issued the message. For example,
When the activation message is issued in step 514 using the sound reading performance diagnosis data as the condition data, if the sound reading performance diagnosis does not end even after the time allocated to the sound reading performance diagnosis has elapsed, a timer The object 600 issues a process end request message to the diagnostic object 500.

Now, the single note reading ability, double note reading ability, clef reading skill, right and left hand single note and double note tapping,
If the diagnosis of the rhythm expression, the two-handed performance, and the comprehension of the ideographic symbol is completed within the allocated time, the diagnosis object 500 executes the process of step 570 after the diagnosis. In step 570, a release message is issued to timer object 600. In response to issuing the release message, the timer object 600
(FIG. 8) releases the set for issuing the process end request message in step 608. Therefore, in this case, no process end request message is issued. On the other hand, if the time issued for the current diagnosis item remains in step 572, the diagnosis object 500 gives the remaining time for a diagnosis to be performed in the future. In this case, the time may be given only to the next diagnosis, or the remaining time may be appropriately allocated to a plurality of diagnoses to be performed in the future.

On the other hand, if the diagnosis is not completed within the allotted time, the timer object 600 issues a process end request message to the diagnosis object 500 by the processing of step 606 as described above. In response to the issuance of this message, the diagnosis object 500 executes the processing of step 574 or step 578 depending on whether or not the data indicating the intermediate diagnosis result for the diagnosis item under diagnosis is present in the RAM 13. If there is an intermediate diagnosis result, the intermediate diagnosis result is left as it is in step 574, and the ongoing diagnostic processing is forcibly terminated in step 576, and the process proceeds to the next processing. If there is no intermediate diagnosis result, an extension time is set in step 578, a set message is issued to the timer object 600 together with the time data indicating the extension time in step 580, and the process ends in the RAM 13 in step 582. Set the request flag. Accordingly, the timer object 600 sets the extension time with respect to the time previously specified for the processing of step 606. If the result of the diagnosis during the processing is obtained within the extended time, the process proceeds to the next diagnosis as described above.

If a diagnosis result is not obtained even after the extension of the time, the timer object 600 issues a process end request message again. However, in this case, since the end request flag is set by the processing of step 582, the diagnosis object 50
In the case of 0, the lowest point (for example, 0 point) is temporarily stored in the RAM 13 as a diagnosis result in step 584. Then, in step 586, the end request flag is cleared.

F. Lesson Object (Activation and Process Termination Request) Next, the lesson object 400 (FIG. 6) specified in step 110 of the main program (FIG. 2) will be described. By the process of the step 110, a startup message is issued, and a warm-up
When any of the data representing the review and the practice music is sent as the condition data, the lesson object 400 issues an execution program notification message to the billing object 700 in step 402. At this time, the lesson object 400 also sends data indicating that the lesson is performed to the billing object 700. As a result, the billing object 700 is stored in step 704 in the same manner as described above.
Sets the unit charge data in the RAM to a predetermined amount corresponding to the diagnosis. Therefore, the billing object 700 accumulates the unit fee corresponding to the lesson in the billing data every time the timer object 600 measures the predetermined time.

Next, the lesson object 400 issues a set message to the timer object 600 in step 404. At this time, the practice schedule table (FIG. 19) according to the data representing the warm-up, review, or practice music designated as the condition data
The data representing the practice time in is sent to the timer object 600 as time data. In response, the timer object 600 stores the time data sent in step 606 and, after a lapse of the time represented by the same time, sends the message to the object that issued the message (the lesson object 400). Issues a process termination request message.

After the process of step 404, if data indicating warm-up is given as the condition data, the process of step 406 is executed. If the data indicating the review is given as the condition data, the process of step 408 is executed. If the data representing the practice music is given as the condition data, steps 410-410
A practice process using a practice song composed of 418 is executed.

In step 406, a simple note sequence (for example, a note sequence consisting of a plurality of notes whose pitch is simply raised or lowered) is displayed on the display 15, and a performance corresponding to the displayed note sequence is performed. Is instructed,
The user uses the electronic musical instrument 25 to perform a performance according to the displayed note sequence for a time allocated to warm-up.

After each of the warming-up, review, or practice of the practice music (music reading and metronome step), an open message is issued to the timer object 600 at step 420, and the timer schedule is adjusted at step 422. If the practice process is a warm-up or review, these exercises are performed for the allotted time, so that the setting process and the timer schedule adjustment by the timer object 600 are practically meaningless. On the other hand, if the practice process relates to a practice song, it has the same meaning as in the case of the diagnostic object 500 described above. That is, if the various exercises of the practice music are completed within the allocated time, the set state of the timer object 600 is released in step 428, and the remaining time is allocated to the future exercise in step 430.

However, if the practice of the practice music is not completed even after the allocated time elapses, the timer object 600 specifies the lesson object 400 and sets the process as in the case of the diagnosis object 500. Issues a termination request message. In response to the issuance of this message, the lesson object 400 determines whether the data indicating the intermediate evaluation result (scoring result) for the content currently being practiced exists in the RAM 13 or not in step 4.
24 or the processing of step 428 is executed. If there is an intermediate diagnosis result, the intermediate evaluation result is left as it is in step 424, and the content being practiced is forcibly terminated in step 426, and the process proceeds to the next process. If there is no intermediate evaluation result, an extension time is set in step 428, a set message is issued again together with time data indicating the extension time to the timer object 600 in step 430, and an end request is issued in step 432. Set a flag.

F-1. Reading practice The reading practice routine of FIGS. 11 and 12 will be described. This routine is executed in step 416 of the lesson object (FIG. 6), starts in step 800, and specifies a practice range in step 802. In the specification of the practice range, first, the contents of the current practice are read from the corresponding location of the practice plan data in the hard disk 16 and the first phrase (of FIG. 20) of the practice music data stored in the RAM 13 based on the content is read. specify. Then, every time the process of step 802 is executed, the next phrase (FIG. 20...) Of the practice music data is sequentially designated. If the practice content is a special rhythm part, a special rhythm part (for example, the special rhythm in FIG. 20) is sequentially designated.

Next, at step 804, the lesson object 400 displays the musical score in the specified range on the display 15 based on the data representing the content of the exercise, the musical score data in the practice music data, and the performance data. In this case, for example, if the practice content is scale practice (STEP 1 in FIG. 17), new musical performance data is created by extracting a note sequence having a pitch appearing in a specified range based on the musical performance data in the practice music data. The note sequence corresponding to the performance data is displayed on the display 15. If the practice content is a right-hand performance, a left-hand performance, or a two-hand performance, the right-hand performance part (melody part), the left-hand performance part (accompaniment part) or all the performance parts within the specified range are included in the musical score data of the practice music data. And display it on the display 15. If the practice content is a special rhythm part, a special rhythm part (for example, the special rhythm in FIG. 20) is extracted from the musical score data of the practice music data and displayed on the display 15.
In this case, the fingering may be displayed based on the fingering data.

Next, at step 806, the lesson object 400 corresponds to the newly created performance data corresponding to the note sequence displayed on the display 15 or the musical score displayed on the display 15. The performance data in the practice music data is
To supply. The electronic musical instrument 25 generates a musical tone based on the supplied performance data, and makes the user listen to the model performance sound. If the computer has a built-in tone signal generating circuit, the tone signal generating circuit may be used to generate the model performance sound. next,
In step 808, the lesson object 400 instructs the user to start playing practice via the display 15, and starts time measurement by a timer built in the CPU 11.

The lesson object 400 is
In step 810, the user designates the next note to be played on the score displayed on the display 15, and in step 81
At 2, the user waits for a key to be pressed on the electronic musical instrument 25. If the user presses any key of the electronic musical instrument, based on the determination of “YES” in step 812, the pitch data corresponding to the key pressed in the RAM 13 in step 814 is pressed in the key pressing sequence. Write to data. Next, in step 816, it is determined whether or not the end request flag is “1”.
It is determined whether the key depressed in step 8 corresponds to the note indicated in step 810. Since the end request flag is normally set to "0", the program proceeds to step 818, and if it is a correct key press, the pitch data corresponding to the key pressed in the RAM 13 is correctly pressed in step 820. Write to key string data. Then, in step 822, it is determined whether or not the practice of the specified range has been completed.

If the practice in the designated range has not been completed, "NO" is determined in the step 822, and the step
The processing consisting of 10 to 822 is continued until the practice of the specified range is completed. During this repetition process, keystroke sequence data and correct answer keystroke sequence data in the designated range are sequentially formed. On the other hand, during the repetition of the steps 810 to 822,
If an incorrect key is pressed by the user and “NO” is determined in step 818, the lesson object 400
Executes the processing after step 834.

In step 834, the total error data is incremented by "1" to measure the total error. Next, it is determined in step 836 whether or not the error is continuous, and if not, the program proceeds to step 842. On the other hand, if the mistakes are consecutive, the contents of the mistake are analyzed in step 838 by comparing the depressed key with the note to be played, and in step 840 the mistake content and an appropriate instruction for the mistake are given. It is displayed on the display 15. For example,
When a key corresponding to a pitch without the symbol #, b is pressed for a note with the symbol #, b, the note is marked with the symbol #, b. The meaning of the symbol is explained. As a result, the user can take measures to prevent mistakes in the next performance.

In step 842, it is determined whether or not the total number of errors exceeds a predetermined value based on the total error data. If the total number of errors exceeds the specified value, the program proceeds to step 844 and thereafter, which will be described later. If the total number of errors does not exceed the specified value, the program returns to step 812, and waits for a new key press in step 812. Such steps 810-822
By the processing of steps 834 to 842, keystroke sequence data including incorrect keystroke and correct keystroke sequence data are sequentially formed. When all the correct keystroke operations in the specified range are completed, the lesson object 400 returns “YES” in step 822. , And the ratio of the number of correct answer keystroke data to the keystroke string data is calculated as the correct answer ratio in step 824. In step 826, the keystroke string data and the correct answer The error location is displayed by comparison with the keypress row data.

Next, in step 828, it is determined whether or not the end request flag is "1". Since the end request flag is normally set to "0", the program proceeds to step 830. . In step 830,
It is determined whether the calculated correct answer rate exceeds a predetermined rate (for example, 80%). If the correct answer rate does not exceed the predetermined rate, the program returns to step 806, and the key pressing practice in the same designated range as the previous time is repeated.
On the other hand, if the correct answer rate is equal to or higher than the predetermined rate, the program proceeds to step 832, and in step 832, it is determined whether or not the entire range of the practice music to be designated has been completed.
If the entire range has not been completed, execute the program in step 8
02, the next designated range is determined, and the user is caused to practice key pressing in the same manner as described above.

If the whole range has been completed, at step 848 the correct answer rate, the number of trials, the required time, etc. of each specified range are compared with the performance data in the music data, and the practice result is scored. The result is written in the achievement table (FIG. 21) provided on the RAM 13. In this music reading practice, the score is given with emphasis on the music reading ability, and points are entered in columns such as accuracy of stem and derived sounds, clef, double tone, and two-handed combination.

Next, the case where it is determined in step 842 that the total number of errors exceeds the specified value will be described. In this case, the lesson object 400 displays on the display 15 that either the re-challenge or the lesson abort is selected in step 844, and the user is prompted to select one. If the user chooses to retry,
By the processing of step 846, the program is stored in step 80.
Return to 6 and resume from the model practice in the specified range. on the other hand,
If the user selects lesson cancellation, the program proceeds to step 848 by the processing of step 846.

A case will be described in which the end request flag is set to "1" in step 432 in response to the process end request message by the object 400 during reading practice by the lesson object 400. In this case, since it is determined “YES” in both steps 816 and 828, the performance practice is interrupted and the program proceeds to step 848. If the error count is increased or the process end request message is issued, the score in step 848 is set to a bad value. Then, in step 850, the execution of the music reading practice routine ends.

F-2. Metronome Step Practice The metronome step practice routine of FIGS. This routine is executed in step 418 of the lesson object (FIG. 6).
This metronome step practice routine is the same as the above-described practice routine of reading music in FIGS. Only different parts will be described.

The execution of the metronome step practice routine is started in step 860, and the lesson object 400 stores the tempo (stored as a part of the performance data) of the practice music in step 862 according to the current practice content in the practice plan data. And starts generating a reference tempo sound every quarter note at the corrected tempo. Therefore, the trainee practices the performance while listening to the tempo sound. Subsequent steps 802 to 816 are the same as the music reading practice routine. In step 864, unlike the music reading practice routine, not only pitch matching but also
It is determined whether or not the key is pressed correctly, taking into consideration whether or not the key pressing timing is within the allowable range of the timing to be played. This timing is determined in step 80.
This is performed by comparing the time measured by the timer started at 8 with the value of the performance data in the music data corrected by the current practice content (tempo) of the practice plan data.

The processing after step 820 is the same as that in the reading practice routine, except that the routine 836 to
Step 840 is omitted. This is to prevent the performance from being interrupted even if an incorrect key is continuously pressed.

In writing to the achievement level table in step 848, rhythm is emphasized, speed,
The scores are entered in the fields such as rhythm expression and two-handed combination, and the total achievement time of the reading practice and the metronome step exercise is also entered.

G. Lesson Object (End) Next, the lesson object 400 (FIG. 6) specified in step 114 of the main program (FIG. 2) will be described. When the lesson object 400 is designated and the end message is issued by the processing of step 114, the object 400 executes the processing of step 434 and thereafter.

In step 434, based on the practice result, the execution date, the success rate, and if the success rate is equal to or more than a predetermined score, the end symbol and the consumption time are added to the practice plan data on the hard disk 16. In this case, the success rate is calculated based on the contents of the achievement degree table, with emphasis on performance practice related to the practice contents of the practice plan data. For example, practice with slow tempo emphasizes the accuracy of the stem and derived sounds, clef, key signature, and two-handed combination.
Also, in the case of performance practice at the normal tempo, emphasis is placed on the key pressing speed of the stem sound and the derived sound, the rhythm expression, and the combination of both hands. The consumption time is the total time of the reading practice and the metronome step practice stored in the achievement degree table.

Next, in step 436, the user model data in the hard disk 16 is updated. in this case,
Referring to the achievement level table and referring to the attribute data of the song data, for each item whose achievement level exceeds the required level of the attribute data, the standard time in the attribute data and the achievement time in the achievement degree table Is changed for each of the above items. The value to be changed is, for example, a value obtained by adding each item data of the user model data to a value calculated by (constant × (standard time−achieved time) / standard time).

Next, the lesson object 400 displays the practice results on the display 15 at step 438. In this case, in the reading practice and the metronome step practice, the places and the evaluations where there are many mistakes in this practice are displayed on the display 15, and the comments on the performance at the same places and the comments for overcoming the bad evaluations are displayed on the display 15. To be displayed. Appropriate evaluations and comments to be displayed are selected from a large number of evaluations and comments prepared in advance. Then, at step 440, homework is displayed. In this case, the practice task corresponding to the erroneous portion and the comment is displayed on the display 15.

Next, the lesson object 400 displays the amount of money represented by the billing data stored in the RAM 13 on the display 15 in step 442, and stores the billing data in the user information corresponding to the hard disk 16. Store as data. The billing data, training plan data, user model data, etc. on the hard disk 16 are stored in the host computer 2.
2 via a communication line, and the computer 2
2 is used for collecting charges and transmitting comments.

B. Second Embodiment Next, a second embodiment of the present invention will be described. The configuration of the second embodiment is also configured as shown in FIG.

However, in the second embodiment, the program storage area of the hard disk 16 has
A program corresponding to the flowchart shown in FIG. 26 is stored. As shown in FIG. 27, in the user information storage area of the hard disk 16, user information i (i
= 1 to n) are stored.

The user information i includes user name data, teaching method data, practice plan data, user model data, and practice music data. The user name data is data representing the name of the user. As will be described in detail later, the teaching method data is data representing one teaching method (teacher) selected by the user from a plurality of teaching methods (teachers) prepared in advance. The practice plan data is stored in the form of a table as shown in FIG. 28, and includes a plurality of practice contents (right hand, left hand, two-handed performance practice at various tempos, etc.) necessary to learn the performance of one practice song. ) In chronological order, and data indicating the end of each of the practice contents. The user model data is not directly related to the invention according to the second embodiment and will not be described in detail. However, the user model data is data representing a user's performance level formed based on a diagnosis, a practice result, and the like.

The practice music data is data relating to the music being practiced, and is composed of music title data, musical score data, performance data, fingering data, and attribute data. The song name data indicates a song name. The musical score data is image data for visually displaying the notes, rests, and the like on the staff notation relating to the music on the display 15. The performance data includes data representing the performance tempo of the music, the pitch of each note,
It is composed of data representing the note length, rest, etc. according to the progress of the music. The fingering data is data representing a hand and a finger to press each note of the music. The attribute data includes data representing a performance level necessary for playing the music, data representing the type and characteristics of the music, and the like.

The internal database 17 stores a large number of sets of music data (hereinafter, referred to as “general practice songs”) corresponding to a large number of songs selected as normal practice songs (hereinafter, “general practice songs”).
General music data) and a large number of music data (hereinafter, specific music data) respectively corresponding to a large number of music or a part of music selected as practice music for a specific task (hereinafter, specific music). And are stored separately. The specific practice music is a short measure of about 4 bars or 8 measures and is provided to overcome a specific problem in the performance practice of the general practice music. Contains data representing the assignment. However, when referring to practice music and music data without distinction, it refers to both general practice music and specific practice music, as well as both general music data and specific music data. Each piece of music data is composed of the above-described music title data, musical score data, performance data, fingering data, and attribute data (see FIG. 27).

In this computer device,
Flexible disk 23 and compact disk 24
Is used as an external recording device.
The programs 2 to 26 are recorded in advance and used to install the programs on the hard disk 16.

The music training system thus configured also operates by the CPU 11 executing a program (not shown) stored in the ROM 12 and the above-described program stored in the hard disk 16 or the like. Before this operation, by executing a program (not shown), a part or all of the program previously recorded or stored on the flexible disk 23 or the compact disk 24 is installed on the hard disk 16, and the external database 21, the flexible disk 23 Alternatively, the music data stored in the compact disk 24 is transferred to the internal database 17.

When the user activates the main program shown in FIG. 22, the CPU 11 executes step 11 shown in FIG.
At 00, the execution of the main program is started.

After the execution of the main program is started, the CP
U11 displays an inquiry about the user name on the display 15 in step 1102, and waits for the user to input the user name. When the user inputs a user name using the keyboard 14, the CPU 11 searches the user information storage area in the hard disk 16 to determine whether the user is a new user or a registered user. If there is, a storage area for one user information is secured in the user information storage area, and a user name is written in the storage area. On the other hand, if the user is a registered user, only the practice music data in the corresponding user information from the hard disk 16 is transferred to the RAM 13.

Next, the CPU 11 selects a general practice song in step 1104, selects a teaching method in step 1106, and creates training plan data in step 1108. In the processing of these steps 1104 to 1108, the input user name is new, the exercise plan data indicates the end of all exercise contents,
When the user particularly inputs a change in the general practice song using the keyboard 14, the CPU 11 performs the process of selecting the general practice song, the process of selecting the teaching method, and the process of creating the practice plan data. On the other hand, if the user name is already registered, the practice plan data does not indicate the end of all the practice contents, and if the user does not particularly request a change of the general practice music, the CPU 11 executes the program in the next step. Proceed to

In the process of selecting general practice music, a set of general music data is extracted from a large number of sets of general music data in the internal database 17 in consideration of the user's intention, and the general music data is stored in the corresponding area of the hard disk 16 and the RAM 13. Remember each. In extracting general music data from the internal database 17, each music name represented by each music name data in a large number of sets of music data stored in the internal database 17 is sequentially displayed on the display 15, and the user This is performed by selecting a desired music title using the keyboard 14. In this case, if a huge number of sets of general music data are stored in the internal database 17, the user's preference is queried or user model data (representing the user's performance level) is read out. The user's preference or performance level is compared with the required performance level and music type represented by the attribute data in the general music data, and after a small number of sets of general music data are selected as candidates, the user Choose from a small number of general song data. Further, the user may designate a song name and designate general song data in the internal database 17, or the CUP 11 may select random song data from all the general song data in the internal database 17 in consideration of randomness. Alternatively, a selection may be made from among a small number of selected general music data as the candidates.

In the process of selecting the teaching method, the CPU 1
1 displays a plurality of teaching methods (teachers) on the display 15 and prompts the user to designate one of the teaching methods using the keyboard 14. In the second embodiment, as shown in Table 1 below, six patterns of teaching methods are prepared in advance in the teaching method table as six types of teachers 1 to 6. This table is a part of the program shown in FIGS. The teaching methods of these six patterns divide the characteristics of the actual teacher into four elements, for example, requirement levels, training materials, teaching methods, and time management, and divide the teaching methods (the following or to) of the four teaching elements. Classified by combination. The respective methods for the respective elements represent the corresponding methods of the teacher for the respective elements, and are as follows.

Regarding the required level element, "The same practice is repeated until the performance of the practice music reaches a fairly high level." If you go, you will move on to the next exercise. " Regarding the teaching material element, "If you cannot learn a specific task, let them practice playing mainly on specific practice songs corresponding to the task."
And, "Even if a specific task cannot be mastered, the user will practice playing mainly on the general practice music selected by the user."
Divided into types. Regarding the teaching method element,
"Point out the wrong part", "Play the model part of the wrong part", and "Explain the contents of the mistake in sentences".
Divided into types. Regarding the time management element,
"Perform time management and end the performance practice at the predetermined time T1 or further allow the predetermined time T2 to be extended.""Without time management, continue the practice until the scheduled performance practice is completed." And two types.

[0124]

[Table 1]

In Table 1, +, + and the like mean that two kinds of teaching methods such as and and are simultaneously adopted. The teaching method data indicating the teaching method (teachers 1 to 6) designated by the user is written in the corresponding user information on the hard disk 16.

In the process of creating the practice plan data, a practice plan for enabling the selected general music to be played is established based on the performance data and the attribute data in the selected general music data. The data representing the established training plan is stored on the hard disk 16 as training plan data.
Is written in the corresponding user information. For example, if a song is fast-paced, practice with a slower tempo is planned,
If it is difficult to simultaneously perform the right hand and the left hand, the number of independent practice of the left hand and the right hand is planned to be large. In preparing the practice plan data, the user model data (performance level of the user) and the performance level represented by the attribute data in the selected general music data are considered, and the practice plan data is determined in consideration of the user's request. You may make it. In addition,
At the time of creating the training plan data, all data indicating the end of the training is set to “absent”, that is, “0”.

After the processing in steps 1104 to 1108, the CPU 11 determines in step 1110 whether the time management element in the selected teaching method data indicates that the time is to be managed, that is, whether the time management element is Is determined. If the same time management element,
In step 1110, “YES”, that is, it is determined that time management is to be performed, and in step 1112, a timer built in the CPU 11 is set to a predetermined time T1 (for example, 30 minutes). Set the timer interrupt to the allowed state. Thus, the timer starts time measurement, and issues an interrupt command to the CPU 11 after the lapse of the set time T1. On the other hand, if there is the time management element, "NO" is determined in step 1110, that is, it is determined that time management is not to be performed, and in step 1116, interruption by the timer during execution of the main program is set to a prohibited state. In this case, the timer does not issue an interrupt instruction.

Next, at step 1118, the CPU 11 reads out data representing the practice content corresponding to the data representing no first end of the plurality of practice content based on the practice plan data. Then, in step 1120, a practice execution routine is executed. The practice execution routine will be described later in detail, but will be briefly described. First, if it is necessary to process general practice music data and score data according to the read content of the present practice, the data is processed, and the processed general practice music data and score data are cut out for each unit such as a phrase. The score of the cut out portion is displayed on the display 15 based on the score data. The user performs a performance according to the musical score displayed on the electronic musical instrument 25, and stores key-depression string data representing the performance in the RAM1.
3 is stored. Then, by comparing the stored depressed key sequence data with the cut-out performance data, an error in the performance by the user is found, the accuracy of the performance is evaluated, and the content of the error is analyzed.

Next, the wrong key press, evaluation, analysis result, comment, etc. are displayed on the display 15, and if the evaluation is bad, the cutout portion is repeatedly practiced or specified based on the analysis result. To practice a specific practice song to learn the subject. For example, when a specific rhythm cannot be performed, a specific practice song containing a large amount of the same rhythm is performed. Display of these evaluations, analysis results, comments, etc. on the display 15, repetition practice, practice of a specific practice song, etc. are not common to all users, but are based on teaching method data (teachers 1 to 6) selected by the users. Dependent.

When the process of the practice execution routine in step 1120 is completed, the CPU 11 proceeds to step 1122
Then, among the practice plan data stored in the hard disk 16, the data indicating whether or not the exercise corresponding to the current practice content is completed is set to “1”, and the general comment is displayed on the display 15, and step 1124 is performed. Terminates the execution of this main program. This means that this performance practice has been completed. If the evaluation result of the practice is poor, the data indicating the end of the practice is set to “0”.
You may leave it as it is. In this case, the user will practice in the next practice the same content as the current practice content.

On the other hand, as described above, when the timer interrupt is allowed and the timer issues the interrupt instruction to the CPU 11 after measuring the predetermined time T1, the CP
U11 starts the timer interrupt program of FIG. 23 in step 1200. Then, in step 1202, the process currently being executed is temporarily stopped.
Displays on the display 15 whether to end or continue the performance practice, and inquires of the user whether to end or continue the performance practice. If the user selects the end of the performance practice using the keyboard 14, in step 1206, "YE
S ”and the program is stored in step 1122 of FIG.
Proceed to Thus, in this case, step 1
After the process of step 122, the execution of the main program is terminated and the performance practice is terminated as in the case described above.

If the user selects the continuation of the performance practice when inquiring about the end, the CPU 11 determines "NO" in step 1206, and advances the program to steps 1208 and 1210. In step 1208, the timer sets a predetermined extension time T2 (for example, 5 minutes).
In step 1210, the execution of the interrupt program is terminated, and the execution of the temporarily stopped main program is executed again from the stop position. As a result, the performance practice time is extended by the extension time T2.

On the other hand, the timer restarts time measurement by setting the extension time T2 in step 1208, and issues an interrupt command again after a lapse of a predetermined time T2 from this setting. If the interrupt command is generated again, the end of the performance practice is again inquired by the processing of steps 1200 to 1210, and the presence or absence of re-extension is determined. Even if the timers are set to the predetermined times T1 and T2 by the processing of the steps 1112 and 1208, the execution of the main program is performed by the timer for the predetermined time T1 and T2.
If the timer ends before the measurement of T1 and T2, the timer does not issue an interrupt command and the timer interrupt program of FIG. 23 is not executed.

As described above, if the time management element of the teaching method represented by the teaching data is selected to have time management, the steps 1112, 1114, and 1200 are performed.
Through the processing of １２1210, the performance practice time is managed by the timer. If the time management element is selected without time management, the timer interruption is prohibited by the processing in step 1116, so that the performance practice is not managed at all.

Next, the processing of the practice execution routine of step 1120 in FIG. 22 will be described in detail. The details of this practice execution routine are shown in FIG. 24. The execution is started in step 1300, and the CPU 11 specifies a practice range in step 1302. In the designation of the practice range, first, based on the content of the current practice read out by the processing of step 1118 in FIG.
The first phrase (FIG. 29) of the practice music data stored in M13 is designated. Then, this step 1302
Is executed, the next phrase (FIG. 29...) Of the practice music data is sequentially designated.

Next, at step 1304, the CPU 11 displays the music score in the specified range in the music score column A (FIG. 30) of the display 15 based on the music score data in the practice music data. At step 1306, the performance data included in the practice music data and belonging to the specified range is corrected in accordance with the current practice content and stored in the RAM 13 in step 1306. In this correction, for example, if the practice content indicates a performance at a slow tempo, the note length data of the performance data is changed. In step 1308, the corrected performance data is supplied to the electronic musical instrument 25, and the electronic musical instrument 2
Have 5 play the model. Thereafter, in step 1310, after instructing the user to start playing, key press data representing the user's performance of the electronic musical instrument 25 is input via the musical instrument interface 25a, and is sequentially stored in the RAM 13 as a key press data string. . In this case, the keypress data string includes
The key data includes key data indicating a pressed key, key touch data indicating a key touch at the time of key pressing, and time data corresponding to a key pressing time interval measured by a timer built in the CPU 11, that is, a note length. When the performance by the user ends, the CPU 11 executes the program at step 1312.
In step 1312, an analysis evaluation routine is executed.

This analysis evaluation routine is shown in detail in FIG. 25, and its execution is started at step 1330. After the start, the CPU 11 compares the corrected performance data with the key press data string in step 1332 to extract a portion of the user's performance error, and in step 1332 according to the number of errors and the content of the error. To evaluate the performance by the user and digitize the evaluation result. For example, an evaluation score is calculated with 100 points as a perfect score. Next, in step 1336, based on the erroneous part, an appropriate task for overcoming the error is extracted from a plurality of tasks prepared in advance with the program, and data representing the task is specially extracted. R as assignment data
It is stored in the AM 13.

After the processing in step 1336, in step 1338, the processing for avoiding duplication of the teaching contents or adding randomness to the teaching processing for the erroneous portion based on the teaching method data in steps 1340 to 1350. I do. In other words, when the execution of the analysis evaluation routine is repeated many times, an error point is pointed out as the teaching processing (step 134).
0,1342), a model performance of the wrong part (step 13
44, 1346) and the description of the mistaken part (steps 1348, 1350) are appropriately thinned to prevent the same instruction from being presented to the user over and over again.
Specifically, in step 1338, the number of executions of the analysis evaluation routine is counted, and the counted value is stored in the RAM 13 together with the type of the teaching process. A flag indicating whether or not the processing of each teaching method should be executed based on the type is set in consideration of randomness.

After the processing in step 1338, the processing in steps 1340 to 1352 is executed. First, the processing in steps 1340 to 1352 will be described in the case where the flag indicates that the processing of each teaching method should be executed. explain. If an error point indication (corresponding to the teaching method) is selected as the teaching method element represented by the teaching method data, "YES" is determined in step 1340, and in step 1342, the score field A on the display 15 is determined. In this case, a note with the wrong key depressed is displayed differently from other notes (a different color display, blinking display, etc.). If the error point indication is not selected as the teaching method element, “NO” is determined in step 1340, and the program proceeds to step 1344 without pointing out the error point.

If the model performance (corresponding to the above teaching method) is selected as the teaching method element represented by the teaching method data, “YES” is determined in the step 1344, and in step 1346, the erroneous portion is determined. The performance data before and after that is transmitted to the electronic musical instrument 25, and the musical instrument 25 performs the model performance. If the model performance is not selected as the teaching method element, “NO” is determined in the step 1344, and the program proceeds to the step 1348 without performing the model performance of the erroneous portion.

If the description of the wrong content (corresponding to the above-mentioned teaching method) is selected as the teaching method element represented by the teaching method data, “YE
In step 1350, the erroneous reason, the comment corresponding to the reason, and the like are displayed in the comment column B (FIG. 30) of the display 15 and also explained by voice. For example, for a note with the symbols # and b,
In the case where a key corresponding to a pitch to which no symbol # or b is attached is pressed, a note with a symbol # or b and the meaning of the symbol # or b will be described. . If the wrong description is not selected as the teaching method element,
At step 1348, “NO” is determined, and the program is executed at step 135 without describing the incorrect content.
Proceed to 2.

As described above, various teaching methods are adopted for mistakes in performance practice according to the teaching method element that is one of the teaching methods selected by the user.

On the other hand, if the flag indicates that the processing of each of these teaching methods is not adopted by the processing of step 1338, even if each of the teaching methods is selected by the user, the processing is performed based on the flag. In steps 1340, 1344, and 1348, "NO" is determined, and steps 1342, 1346, and 1
Step 350 is not executed. Step 1340
After the processing of 1350, the execution of the analysis and evaluation routine ends at step 1352.

Returning to the description of the practice execution routine in FIG.
The teacher's expression is displayed in the display column C (FIG. 30) of No. 5 according to the evaluation result. For example, step 133 in FIG.
If the evaluation score of No. 4 is 80 or more, a teacher's smiling expression as shown in FIG. 31A is displayed. Evaluation score is 8
If the score is less than 0 and greater than or equal to 50 points, a teacher's head expression as shown in FIG. 31B is displayed. If the evaluation score is less than 50 points and 30 points or more, an angry expression of the teacher as shown in FIG. 31C is displayed. Evaluation score is 30
If it is less than the point, a teacher's crying expression as shown in (D) of FIG. 31 is displayed.

After the processing in step 1314, it is determined in step 1316 whether or not the evaluation point is equal to or larger than the first reference value. If the evaluation point is equal to or greater than the first reference value, “YES” is determined in step 1316, and step 132
At 2, it is determined whether or not the performance practice of the entire range of the practice music has been completed. If the performance practice for the entire range has not been completed, “NO” is determined in the step 1322, and the program is returned to the step 1302, and the steps 1302 to 1302 are performed.
A performance practice of the next designated range consisting of 20 is performed. When the performance practice of the entire range of the general practice music is completed, the process of the practice execution routine is terminated in step 1324 based on the determination of “YES” in step 1322.

On the other hand, if the evaluation point is less than the first reference value,
In step 1316, “NO” is determined, and based on the determination in step 1318 described later, steps 1308 to
Either a repetition practice of the same designated range as the previous practice consisting of 1316 or a special practice of step 1320 is performed. As described above, the first reference value used for the difference between the training methods takes a different value depending on the required level element of the teaching method represented by the teaching data. That is, as the required level element, the above-mentioned "until the performance of the practice music reaches a considerably high level,
If "Repeat the same practice" is selected, the first
A standard score (for example, 80 points) is adopted as the reference value. On the other hand, if the above-mentioned “if the performance of the practice music does not reach a very high level, but proceed to the next practice after performing a certain performance” is selected as the required level element, the first
A relatively low score (for example, 70 points) is adopted as the reference value. As a result, a different method of performance practice is adopted according to the required level element, which is one of the teaching methods selected by the user.

A description will be given of the judgment processing of the step 1318. In the judgment processing, the evaluation point is the second
It is determined whether the value is equal to or greater than the reference value. If the evaluation point is equal to or greater than the second reference value, “Y” in step 1318
Based on the determination of “ES”, the program proceeds to step 1308
And the repetitive training consisting of steps 1308 to 1316 is performed. On the other hand, if the evaluation point is less than the second reference value, a special practice routine is executed in step 1320 based on the determination of “NO” in step 1318. In this special practice routine, a performance practice for a specific music is performed slightly apart from the general music being practiced.

In this case, the second reference value is set lower than the first reference value, and takes a different value depending on the teaching material element of the teaching method represented by the teaching method data. In other words, if "if a specific task cannot be acquired, then practice playing mainly on a specific practice song corresponding to the task" is selected as the training material element, the second reference value will be a relatively high score ( For example, 60 points) are adopted. In addition, if "even when a specific task cannot be mastered, the user practices mainly on the general practice music selected by the user" is selected as the teaching material element, the second reference value is set to a relatively low score (for example, 50 points). Point) is adopted. Also in this case, a different method is used as a performance practice method depending on a training material element which is one of the teaching methods selected by the user.

Next, the special practice routine of the step 1320 will be described.

2 (steps 1332 and 1334 in FIG. 25), the model performance, the input of the performance by the user, and the performance evaluation are performed to calculate the evaluation points. Next, step 1
At 374, the evaluation point is compared with a third reference value. If the evaluation point is equal to or greater than the third reference value, execution of this special practice routine is terminated at step 1378. On the other hand, if the evaluation point is less than the third reference value, a cautionary note based on the analysis result is displayed in the comment column B of the display 15 in step 1376, and the program is thereafter executed in step 1
Returning to step 368, a repetitive practice consisting of steps 1368 to 1374 is performed. As a result, in the performance practice of the general practice music, a special practice is performed on a part that the user is not good at, and efficient performance practice is performed.

Also, in this case, the third reference value is
Different values are adopted depending on the teaching method represented by the teaching method data. That is, when the required level of the teaching method and each element of the training material are respectively, the third reference value is set to a relatively high score, and when the respective elements are each, the third reference value is relatively high.
