Description

  The present invention relates to a performance evaluation apparatus and program for evaluating whether or not a user performance has been performed correctly in accordance with a performance of a presented model. In particular, the present invention relates to a technique for evaluating whether or not only one of the right-hand part and the left-hand part has reached a pass line even when evaluating a two-hand performance and presenting an evaluation result.

Conventionally, a task tune (example performance) is presented to the user, and it is evaluated how correctly the performance performed by the user (user performance) is performed along the presented task tune. A performance evaluation apparatus and a program for presenting an evaluation result are known. As an example of such an apparatus, there is an apparatus described in Patent Document 1 shown below.
JP 10-187021 A

  In the apparatus described in Patent Document 1, the user can perform step-by-step performance lessons according to his / her ability, such as performance practice with only the right hand, performance practice with only the left hand, and performance practice with both hands. It is possible to step up the user's performance technique in the order of these steps. Specifically, in comparison with performance data (model performance data for right-hand performance, left-hand performance, and two-hand performance) which is a model stored in advance with user performance data generated according to the user performance, It is determined and presented to what extent the user performance is correct compared to the model performance. Then, if the two-handed performance is passed, the user can move to practice (lessons) of the task music of the next performance level that makes the performance more difficult.

  In the conventional apparatus as described above, a comprehensive performance evaluation is performed by combining the right hand part and the left hand part when practicing a two-hand performance, and it is determined whether or not the two-hand performance has reached the pass line. ing. For this reason, playing with only one hand, such as the right-hand part or left-hand part, has the technology to reach the passing line, but if both hands are used, the performance will not reach the passing line even if the performance is unsatisfactory. Therefore, when practicing two-handed performance, it is difficult to know whether the performance of the right hand or the left hand is not good, and the performance practice tends to be stopped.

Therefore, for example, Patent Document 2 shown below discloses an apparatus that compares user performances with model performance data for two-handed performance, right-handed performance, and left-handed performance, and presents all the comparison results as scoring values. Yes. According to this, the user can understand whether the performance performed by himself / herself is the closest to the two-handed performance, right-handed performance, or left-handed performance by comparing the presented scoring values. .
JP 2004-38049 A

  By the way, in the conventional apparatus as described in Patent Document 1 and Patent Document 2 described above, the pitch and pronunciation timing of individual musical sounds in the performance data of the model are evaluated according to the performance operation by the user. The performance input sound is compared with the input performance input sound (specifically, user performance data). If the performance input sound is considered to be the same, the performance input sound is determined to be correct. And if there are many correct answers, it will be considered as a high score and it will determine with having reached the passing line. This can be said to be an evaluation by a so-called deduction method. Therefore, if the user inputs a sound other than the correct answer (extra input) by mistouching in addition to the correct sound, the proportion of incorrect answers will increase, and as a result, the score will not increase. It will be determined that the pass line has not been reached.

  However, if the user mistouches a sound other than the correct answer in addition to the correct answer, the performance input sound other than the correct answer that was precisely mistouched even though the correct answer was input. If it is determined that the answer is incorrect, there is an inconvenience that since the score does not increase and the passing line is not reached, the practice of the next assignment cannot be performed. In such a case, the performance practice is stagnated there, and the user cannot stop moving at all. Therefore, there is a possibility that the user stops the performance practice there.

  The present invention has been made in view of the above points. When evaluating a two-handed performance by a user, the evaluation results of the right-hand part and the left-handed part are evaluated even if there are many mistouches and the evaluation of the two-handed performance has not reached the pass line. It is an object of the present invention to provide a performance evaluation device and a program that can show whether or not only one of them has reached the pass line.

  The performance evaluation apparatus according to the present invention obtains user performance data generated in response to a performance operation by a user, supply means for supplying example performance data including a plurality of performance parts including at least a right hand part and a left hand part. The acquisition means for storing the acquired user performance data is compared with the supplied sample performance data and the stored user performance data, and the user performance is divided into performance parts for the right hand part and the left hand part. Comparison evaluation means for evaluation and presentation means for selecting and presenting performance evaluation results according to the combination of performance evaluations for each performance part.

  According to a preferred embodiment of the present invention, the comparison / evaluation means has a time width from a predetermined time before the start of the reproduction of the musical sound to be processed in the supplied model performance data to the end of the reproduction of the musical sound. A determination means for determining whether at least one user performance data having the same pitch as the musical sound to be processed is input among the user performance data, and a determination that the input is based on the determination And adding means for counting correct sounds for each performance part, and evaluation means for evaluating performance for each performance part in accordance with the counted number of correct sounds.

  According to the present invention, performance evaluation is performed by dividing the user performance by performance part, and a performance evaluation result is selected and presented according to the combination of performance evaluations. At that time, it is determined whether at least one user performance data having the same pitch as the musical sound is input in a predetermined time width based on the musical sound to be processed in the model performance data. Based on the determination, the correct sound is counted for each performance part, and the performance is evaluated for each performance part according to the counted number of correct sounds. That is, the performance evaluation of each of the right hand part and the left hand part is performed on the assumption that there is a correct performance input when there is at least one musical tone having the same pitch as the model performance data without scoring mistouch. In this way, the user can know the part that was able to perform well even though both-hands performance was rejected, so the user can continue performance practice conscious of the part for which the performance skill is insufficient, Since mistouching is not targeted for deduction, the user can enjoy performance practice easily and easily. Furthermore, since it is easy to pass both-hands performance and the user can challenge one after another to practice the performance of difficult task music, there is also an advantage that the performance technique of the user improves faster.

  The present invention can be constructed and implemented not only as a device invention but also as a method invention. Further, the present invention can be implemented in the form of a program of a processor such as a computer or a DSP, or can be implemented in the form of a storage medium storing such a program.

  According to the present invention, when practicing two-handed performance, in addition to evaluating both-handed performance, whether or not only one of the right-hand part and the left-hand part has reached the pass line is evaluated without scoring mistouch. As a result, it is possible for the user to practice two-handed performance while conscious of parts for which performance skills are lacking, and to be able to practice with ease and comfort. .

Information, pitch information, and pronunciation end timing information (duration information). Further, the model performance data may be data including at least the performance data of the right hand part and the left hand part (having part information), or data for each part corresponding to each of the right hand part and the left hand part. May be.

  If no control program is stored in the ROM 2, the control program is stored in the storage device 8 (for example, a hard disk) and read into the RAM 3 to store the control program in the ROM 2. It is possible to cause the CPU 1 to execute the same operation as in FIG. In this way, control programs can be easily added and upgraded. The storage device 8 is not limited to a hard disk (HD), but can be attached in various forms such as a flexible disk (FD), a compact disk (CD), a magneto-optical disk (MO), or a DVD (Digital Versatile Disk). A storage device using a recording medium may be used. Alternatively, a semiconductor memory or the like may be used.

  Note that the electronic musical instrument described above is not limited to one in which the input operation unit 4, the display unit 5, or the sound source 6 is built in one apparatus body, but each is configured separately, and a communication interface such as a MIDI interface or various networks is provided. It goes without saying that the apparatus may be configured to be connected to each other. Furthermore, the performance evaluation device and the program according to the present invention are not limited to being applied to the electronic musical instrument as described above, but may take any form such as a personal computer, a portable communication terminal such as a mobile phone, a karaoke device, or a game device.

When applied to a portable communication terminal, not only when a predetermined function is completed with only the terminal, but also a part of the function is provided on the server side, and the predetermined function is realized as a whole system composed of the terminal and the server. You may make it do.

  Next, “both-hand performance lesson processing” for realizing a performance operation lesson using both hands according to an example will be described with reference to FIG. FIG. 2 is a flowchart showing an example of “both-hand performance lesson processing”. This process is a process executed by the CPU 1 and is started when a lesson mode for two-handed performance is selected according to an operation of a mode selection switch, for example.

  In step S1, model performance data (task music, etc.) is determined according to the operation of the selection switch by the user, and the determined model performance data is read from the ROM 2, the storage device 8 or the like into the RAM 3. In step S2, various settings relating to performance lessons are performed. The various settings include, for example, a method of displaying model performance data (such as a score and a piano roll score) displayed on the display unit 5 to assist the user in performing a performance lesson, a playback tempo and volume of the model performance data, and For example, tone settings.

  In step S3, the input sound list buffer prepared in the RAM 3 and the correct sound number buffer for each part are cleared. Here, the input sound list buffer sequentially stores performance input sounds (user performance data) generated in response to a performance operation by the user. In order to compare the performance input sounds with the model performance data, At least pronunciation timing information, pitch information, and pronunciation end timing information (duration information) are stored. Any information may be stored as long as it is generated in response to a user operation and can be compared with the model performance data (in other words, the stored information varies depending on the data structure of the model performance data). Good). On the other hand, the correct sound number buffer of each part stores, for each part, the number of performance input sounds determined to have been correctly input by comparison with the model performance data in “correct answer determination processing” (see step S7) described later. Separately memorize it.

  Step S4 accepts a lesson start instruction according to the operation of the lesson start button by the user. In conjunction with accepting the lesson start instruction, the individual musical sounds included in the model performance data are started to be read according to the respective sound generation timing information. Thereafter, performance input sounds (user performance data) generated in response to the operation of the performance operator by the user are sequentially added and stored in the input sound list buffer. That is, reception of performance input sounds generated in response to the operation of the performance operator by the user is started, and the received performance input sounds are stored in the input sound list buffer in the order of input (step S5). Of course, a musical sound based on the performance input sound (user performance data) generated in response to the operation of the performance operator by the user may be generated.

  In step S6, individual musical sounds (referred to as model performance data sounds) included in the model performance data are sequentially read in accordance with the respective sound generation timings, and a well-known reproduction process (not shown) is executed. At this time, the model performance data sound to be played is clearly displayed on the score and presented to the user. In step S7, a “correct answer determination process” to be described later is executed for each tone of the model performance data sound after the reproduction process.

  Here, the above-described “correct answer determination process” (see step S7 in FIG. 2) will be described with reference to FIG. FIG. 3 is a flowchart showing an example of the “correct answer determination process”.

  Step S21 is based on the performance input sound list buffer, from a predetermined time before the start of reproduction of the target model performance data sound (for example, a clock length corresponding to the sound duration of a sixteenth note) to the end of reproduction (hereinafter, If there is a corresponding performance input sound, a search is performed to determine whether there is a performance input sound that has the same timing as that of the target model performance data sound. It is assumed that there is a correct sound. For example, a case where the pitch of the target model performance data sound is “C3 (middle center)” will be described as an example. There is only one performance input sound within the determination time, and the pitch is “C3”. It is assumed that there is a correct sound if it is “(center)”, and there is no correct sound if the pitch is other than “C3 (center)”. Further, if there are a plurality of performance input sounds within the determination time and at least one of the pitches is “C3 (middle center)”, there is a correct sound (a sound that is a correct sound). Even if a pitch other than “C3 (middle center)” is input before and after the high “C3 (middle center)”, it is assumed that there is a correct sound), and at least one of those pitches is “C3 It is assumed that there is no correct answer without (center).

  In step S22, it is determined whether or not there is a correct sound. When it is determined that there is no correct sound (NO in step S22), the process ends. On the other hand, if it is determined that there is a correct answer (YES in step S22), it is determined according to the part information whether the target model performance data sound is a right-hand part (step S23). If it is determined that it is the right hand part (YES in step S23), 1 is added to the correct number of sounds in the correct sound number buffer of the right hand part (step S24). When it is determined that it is not the right hand part, that is, the left hand part (NO in step S23), the correct sound number is incremented by 1 in the correct sound number buffer of the left hand part (step S25). A step S26 deletes the performance input sound that is the correct answer among the performance input sounds within the determination time from the performance input sound list. In this way, if there is at least one performance input sound having the same pitch as that of the target model performance data sound within the judgment time, even if a plurality of performance input sounds are input due to mistouch, the correct answer sound There shall be. If there is even one correct sound within the judgment time, the correct number of correct sounds is added (added). On the other hand, even if there is no correct sound or there is an extra performance input sound in addition to the correct sound, Do not subtract (decrease) the number of notes.

  Returning to the explanation of FIG. 2, in step S8, it is determined whether or not the reproduction processing of the last musical sound (final sound) included in the model performance data has been completed. If it is determined that the final sound reproduction process has not been completed (NO in step S8), the process returns to step S6 to determine how correctly the two-hand performance performed by the user has been performed along with the model performance data. The process of evaluating is continuously repeated. On the other hand, when it is determined that the final sound reproduction process has been completed (YES in step S8), a score for each part is calculated based on the number of correct sounds for each part and the number of part sounds of the model performance data ( Step S9). Specifically, the score of each part may be calculated by dividing the number of correct sounds of each part by the number of musical tones of the corresponding part of the model performance data, but the present invention is not limited to this. In step S10, an evaluation message is selectively determined from the calculated combination of scores of each part and notified to the user. In this case, a total score is calculated based on the total number of correct sounds of all parts and the total number of sounds of all parts of the model performance data, and the calculated total score is notified to the user. The comprehensive judgment concerning the user's both-hand performance is presented together with the evaluation message.

  Here, a method of using an evaluation table as an embodiment for determining an evaluation message from the score of each part will be described with reference to FIG. FIG. 4 is a conceptual diagram showing an example of the data structure of the evaluation table. The evaluation table is stored in advance in the ROM 2, RAM 3 and the like, and as shown in FIG. 4, depending on the combination of the score of the right hand part and the score of the left hand part, a simple comprehensive judgment (in the figure, ○ is passed, × is In addition to (Fail), an evaluation message for notifying the user whether or not only one of the right hand part and the left hand part has reached the pass line is stored as a further evaluation result.

  In the example shown here, when both the right-hand part and left-hand part scores are “60 points or more”, the overall judgment of the two-hand performance has reached the pass line (both right hand part and left hand part pass). Therefore, “Excellent” indicating that both left and right performances are excellent is presented as an evaluation message. If one of the scores for the right-hand part or the left-hand part is "59 points or less", the overall judgment has not reached the passing line, but either the right-hand part or the left-hand part (not less than 59 points) is the passing line. And “R Part is Nice” indicating that the right hand performance is excellent (or “L Part is Nice” indicating that the left hand performance is excellent) is presented as an evaluation message. If the score of both the right hand part and the left hand part is “59 points or less”, the overall judgment has not reached the pass line, and either the right hand part or the left hand part alone has not reached the pass line. Since it is determined, “Good” indicating that both performances of the left and right have not reached a sufficient performance level is presented as an evaluation message. In addition to the evaluation messages described above, a comprehensive judgment or a total score (for example, total number of correct sounds of all parts / all parts) for notifying the user whether or not the two-hand performance has reached the pass line. It goes without saying that it is possible to present a% display of the total number of example sounds.

In addition, the acceptance criteria (score) of each part may be common or may be different for each part. Further, the acceptance criteria (scores) of each part may be changed in stages by the user or edited to an appropriate value.
The evaluation message is not limited to the content shown in the above embodiment. Further, the combination of the score of the right hand part and the score of the left hand part may be further subdivided to increase the types of evaluation messages.

  Returning to the description of FIG. 2, in step S <b> 11, it is determined whether or not to perform a two-handed lesson again using the same model performance data (such as a task tune) based on the user selection. If it is determined that a two-handed lesson is to be performed again using the same model performance data (YES in step S11), the process returns to step S3 to repeat the processes from step S3 to step S11. If it is determined that a two-handed lesson will not be performed again using the same model performance data (NO in step S11), the user performs a two-handed performance using another song or a different phrase, that is, another model performance data. It is determined whether or not to perform the lesson (step S12). If it is determined that another model performance data will be used to perform a two-handed lesson (YES in step S12), the process returns to step S1 and the processes from step S1 to step S12 are repeated. If it is determined not to perform a two-handed lesson using different model performance data (NO in step S12), the process ends.

  As described above, the right-hand part and the left-hand part are played by a scoring system in which, if there is at least one performance input sound with the same pitch as the model performance data within a predetermined time without scoring mistouch, In addition to evaluating each of the evaluation results for each part, the overall judgment of both-handed flipping according to the combination of the evaluation results of each part indicates to the user whether the right hand part and the left hand part have both passed the pass line even if the pass line has not been reached. It was made to present. Accordingly, since the user can know the left or right performance that has been successfully performed while the two-hand performance is rejected, the user can enjoy the performance practice more easily and comfortably. In addition, especially for beginners, since mistouch is not subject to deduction, it will be possible to challenge the performance of difficult task songs one after another without feeling stress, which will lead to opening up the path of improvement more quickly.

The evaluation message may be notified after the reproduction of the target model performance data has been completed (in this case, the evaluation message is notified in units of one song or phrase), or for each range designated in advance by the user. You may make it alert | report every time (for example, a multiple measure unit etc.) (In this case, for example, an evaluation message is alert | reported several times during the performance practice in the unit of 1 music).
Note that during performance lessons, the performance data to be played is not limited to the display of a musical score or a piano roll score, but is displayed by the mini keyboard displayed on the display unit 5 and the individual keys that are the performance operators (4). It may be due to the lighting of an LED guide lamp disposed in the vicinity of. Further, not only the model performance data sound to be played, but also the pitches assigned to the keyboard played by the user may be presented so that they can be distinguished from each other in different display modes.

  In addition to the right hand part and the left hand part, there may be a pedal keyboard part as a part where the user can perform a performance lesson. In that case, in addition to the right hand part and the left hand part, the performance of the pedal may be further evaluated, and an evaluation message may be selectively determined and presented according to the combination of the evaluation results of these parts. For example, if “all parts are 60 points or more”, “I was able to do it very well”, if “the pedal only is 59 points or less”, “(the hand part) was done well.” "Let's do the best part.)", "If the right hand (left hand) part is 59 points or less" "I did well. (Let's do the right hand (left hand) part.)", "Right hand (left hand) If the part is 60 points or more, the right hand (left hand) part is good. If the pedal part is 60 points or more, the pedal part is good. If all the parts are 59 points or less, you can selectively determine and present an evaluation message according to the combination of performance evaluation results for each part, such as “I did my best”. Good. Of course, the evaluation message is not limited to the contents described above, and the user can grasp the part that has passed the pass line among the multiple parts even if the overall performance judgment by combining multiple parts has not reached the pass line. Any content can be used.

Although it is convenient to notify the evaluation message by display, the present invention is not limited to this, and the evaluation message may be notified by sounding or the like.
It may be configured so that the user can appropriately switch the scoring system before the start of the performance lesson. In that case, the scoring method may be appropriately switched to the scoring method shown in the “correct answer determination process” according to the present invention described above, the well-known scoring method, or other methods.
In the above-described embodiment, when at least one of the right-hand part and the left-hand part is presented as an evaluation message, the better evaluation result is presented (“R Part is Nice”). ”Or“ L Part is Nice ”), in order to know whether the user has reached the pass line with only one of the right-hand part and the left-hand part, it is practical to present the worse evaluation result. Is the same.
