Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a performance determination apparatus, and more particularly to a performance determination apparatus that can specifically evaluate whether or not a performance can be performed according to a performance instruction performed based on performance data prepared in advance.
[0002]
[Prior art]
2. Description of the Related Art There is known an apparatus for instructing performance by playing performance data stored in a storage medium on a personal computer (hereinafter referred to as “personal computer”) and displaying a musical score sequentially on a screen. For example, in Japanese Patent Laid-Open No. 9-305171, a scroll bar having a length corresponding to a key pressing time of a musical tone is displayed corresponding to a key to be pressed on a keyboard figure displayed on the screen. A performance instructing device is disclosed in which a bar is scrolled so as to approach a keyboard figure according to reproduction of automatic performance data.
[0003]
According to this performance instruction device, the key pressing time can be intuitively recognized by the length of the scroll bar, and the performance timing can be predicted by the distance between the scroll bar and the keyboard figure. In addition, since a plurality of scroll bars having different key pressing timings are displayed at the same time, the performance data following the performance data currently being pressed can be predicted, and a smooth performance can be expected.
[0004]
The scroll bar is scrolled forward when the practitioner plays at the correct pitch, and waits without proceeding to the next performance instruction until the practitioner plays at the correct pitch. By this method, it is possible to steadily advance the practice while confirming whether or not each note has been played at the correct pitch. However, since the performance is uniform and variations in performance are not allowed, it is insufficient in terms of enjoying the performance.
[0005]
In view of this, there has been proposed a performance determination device that allows a music piece to progress as long as it falls within a predetermined pitch data range even if it does not perform according to performance data (Japanese Patent Laid-Open No. 2002-175072). This publication also discloses that it is possible to loosely judge a difficult song, or to learn performance techniques while enjoying music by adjusting judgment methods and judgment criteria according to age and skill even with the same performance data. .
[0006]
[Problems to be solved by the invention]
As described above, in the past, practice was performed while confirming the performance one note at a time, and the order of key press was acquired. It was thought to be able to perform a natural performance on the rhythm.
[0007]
However, it is often difficult for both the simple practice to play while checking the sound one by one and the advanced practice to play along with the accompaniment and metronome sound, so the practitioner cannot be attached. .
[0008]
If the skill level of the practitioner can be judged in detail, the practice judgment method and judgment criteria can be adjusted with high precision, so that the practitioner can perform without difficulty and expect improvement. However, conventionally, the determination method and the determination standard are adjusted only by whether or not the pitch is in accordance with the sample.
[0009]
Therefore, a system that can recognize the skill by judging the performance result of the practitioner from various angles and determine the determination method and the determination criterion based on the skill is desired.
[0010]
An object of the present invention is to provide a performance determination apparatus that can determine a practitioner's skill with high accuracy by judging the performance results of a practitioner from various perspectives in response to the above-described demand.
[0011]
[Means for Solving the Problems]
In order to solve the above-mentioned problems and achieve the object, the present invention provides a performance determination apparatus for evaluating a performance performed at a pitch according to an instruction in accordance with the performance instruction displayed by the performance instruction means. A performance result storage means for storing performance timing information, a determination means for comparing the performance timing information with performance timing information included in a performance instruction, and detecting a difference between the performance timing information and the determination means. A first feature is that the apparatus includes an evaluation unit that evaluates performance according to the magnitude of the detected difference.
[0012]
In the present invention, a plurality of items are stored for each performance musical sound as information relating to the timing of the performance, and the evaluation means extracts the highest rated item among the plurality of items for all performance musical sounds, and averages them. The second feature is that the performance is evaluated by the value.
[0013]
In addition, the present invention has a third feature in that the information related to the performance timing includes a key-on time and a key-off time, a gate time and a step time.
[0014]
According to the first to third characteristics, the performance is evaluated by comparing the information regarding the timing of the performance between the actual performance and the performance instruction. Therefore, unlike simply judging whether or not the pitch matches the performance instruction, it is possible to determine the player's sense of rhythm and also determine the precision of the performance.
[0015]
In particular, according to the second feature, the performance is evaluated by a plurality of evaluation items determined based on the information regarding the timing of the performance, and is evaluated based on all the musical sounds through the performance. Detailed determination is possible.
[0016]
In addition, the present invention has a fourth feature in that the information related to the performance timing further includes a value of a ratio between the actual performance time and the performance time according to the performance instruction. According to the fourth feature, it is possible to determine whether or not the performance instruction can be generally achieved, not the evaluation of whether or not the performance can be performed according to each performance instruction.
[0017]
Further, the present invention has a fifth feature in that the performance evaluation is an evaluation for each information of a plurality of items related to the timing of the performance, and a means for comprehensively displaying the evaluation for each information in a graph is provided. . According to the fifth feature, since a plurality of items are comprehensively displayed, it is possible to easily understand the advantages and disadvantages of the performer.
[0018]
Furthermore, the present invention has a sixth feature in that the graph display displays a performance instruction display on the same screen. According to the fifth feature, the performance evaluation corresponding to the performance instruction can be confirmed while viewing the displayed performance instruction.
[0019]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 2 is a block diagram showing a configuration of a performance self-study apparatus including a performance determination apparatus according to an embodiment of the present invention. In FIG. 1, a personal computer 1 includes a personal computer main body 11, a keyboard 12 and a mouse 13 as input devices, and a display 14 as an output device. A personal computer main body 11 having a known configuration having a hard disk, ROM / RAM, or the like can be used. It is preferable to provide an interface capable of inputting / outputting MIDI signals.
[0020]
The keyboard instrument 2 includes a keyboard 21 and a sound system 22. The keyboard 21 includes a detection circuit 23 that detects key depression and key release, and a sound source device 24 that generates a musical sound according to detection information of the key depression and key release. When the detection circuit 23 detects a key press / release of the keyboard 21, a tone is generated by the tone generator 24 and output (sounded) through the sound system 22. The keyboard instrument 2 is also preferably provided with a MIDI interface. The overall operation of the keyboard instrument 2 is controlled by a microcomputer (not shown).
[0021]
The personal computer main body 11 and the keyboard instrument 2 are connected via an interface (not shown) (for example, a MIDI interface) so that signals can be transmitted and received between them.
[0022]
In the performance self-study apparatus, the practice music can be supplied from the outside, or can be stored in advance in a hard disk or the like. The practice music is prepared as performance data such as pitch data (note number), key press / release data (key on time, key off time), volume, velocity, tempo data and the like. The performance data includes data other than the above-mentioned data, but it is not a main part of the present invention and will not be described.
[0023]
The selected practice song is not limited to playing from the beginning of the song, but may be played from the middle of the song. The part to be practiced can be specified automatically or manually by the performer. The practice point can be specified for each predetermined range (called a unit). The unit is composed of one or more bars, and the number of bars constituting one unit increases as the level of proficiency, that is, the grade increases.
[0024]
Here, the unit is described as being composed of a plurality of bars, but the structure of the unit is arbitrary and can be composed of musical sound information in an arbitrary range without being limited to bars. In short, it is only necessary to configure the unit to include a wide range of musical tone information so that a longer performance can be practiced at once as the grade becomes higher. For example, by using one or more motifs or phrases as one unit, natural musical practice is possible.
[0025]
When the unit is automatically specified, the unit to be practiced is automatically specified according to the scheduled progress. For example, the proficiency level is automatically determined by the personal computer 1 based on the performance result, and a unit is designated with consideration given to the fact that the proficiency level has reached the acceptance standard so as not to practice repeatedly. On the other hand, when the unit is manually specified, the player himself can arbitrarily specify the unit he / she wants to practice. It is also possible to cancel the unit designation mode by the performer himself and return to the mode that can be designated automatically. The mode selection screen can be included in the performance data to be displayed on the display 14 at a predetermined time.
[0026]
FIG. 3 is an example of the lesson menu, and is a diagram showing units for each grade corresponding to the score. In the figure, for the musical score for twelve bars displayed on the display 14, units are set for each grade. If the song is long, you can scroll this screen to the end of the song. Further, instead of scrolling the screen, a part or the whole of the song may be displayed arbitrarily by expanding or reducing the display width. For example, the screen can be enlarged or reduced by operating the “+” and “−” buttons at the lower left of the screen.
[0027]
Grades (1), (2), (3), (4), and (5) are set in descending order of the proficiency level of performance, and units with different sizes are set according to each grade. That is, the lowest grade (5) constitutes one unit with two measures, and the next highest grade (4) constitutes one unit with four measures. In this way, the number of bars constituting one unit is increased as the grade becomes higher.
[0028]
The lesson menu is a grade table that allows the performance based on the performance results to be seen at a glance, and is also a display of the unit to be practiced next. That is, when the performance of the designated unit is completed, the performance is compared with the performance data to determine the grade. The grade is displayed in the lesson menu with characters representing the rank, and units that do not meet the acceptance criteria are designated again.
[0029]
In the example of FIG. 3, the practice of the unit U1 consisting of the first and second measures of grade (5) is finished, and the unit U2 consisting of the third and fourth measures is displayed as the unit to be practiced next. . The grade is displayed for the unit that has finished playing. The grades are displayed in the order of rank in the letters S, A, B, C, D. A rank “S” and a band indicating acceptance are displayed on the units U1 and U3 that have passed the acceptance criteria. However, this ranking is only an example, the rank classification can be set arbitrarily, and the acceptance criteria can be increased as the grade goes up. If the acceptance criteria is not met, the unit designation is not updated and the same unit is designated again.
[0030]
In the mode in which the unit is automatically designated, among the units that have not reached the passing score, a unit that is played at an early stage in the same grade is designated.
[0031]
Since the units having the same musical tone information are collectively managed, for example, when unit U1 reaches the passing score in the figure, from the ninth bar and the tenth bar having the same musical tone information as unit U1. Unit U3 has also been practiced, that is, the display of the grade is changed. Therefore, duplication practice of a mastered unit is avoided.
[0032]
The performance data of the designated unit is reproduced, and a key pressing instruction as described later is displayed on the display 14 based on the performance data. According to the display of the key pressing instruction, the performer can repeatedly practice until the proficiency level of performance increases for each unit, that is, until a predetermined pass determination is made.
[0033]
When all the units are judged to pass the grade currently being practiced, a larger unit is designated with the grade above it, and the performance data is reproduced. For example, if grade (5) passes, the process proceeds to grade (4), unit U4 is designated and performance data is reproduced. In grade (4), you will practice as many bars as grade (5). The higher the grade, the higher the difficulty level, that is, the tempo and acceptance criteria, so that more advanced practice according to the proficiency level will be possible. The grade determination will be further described later.
[0034]
On the other hand, when practicing in manual mode, performance data can be played back by designating an arbitrary unit, so you can practice until you are satisfied with it. However, even in the manual mode, if the unit can be specified arbitrarily, it is difficult to improve the result of the practice. For example, it is better not to raise the grade until the grade reaches a passing grade. In other words, until all the units in the grade reach the passing score, only the unit in the current grade can be designated, and the unit in the higher grade cannot be designated.
[0035]
Each unit can have the following data structure. As unit data, unit performance information, link information, and performance information can be included.
[0036]
The unit result information is a practice result for each unit, and can include a high score, an average score, a result registration date, and the like. Units with the same musical sound information are managed with common unit performance information. It has a unique ID and enables unit identification.
[0037]
The link information is link information for each unit, and has a unit start position and end position (both are time information) from the beginning of the song, and a link ID for linking a plurality of units having the same musical tone information. The grade information includes arrangement information of link information for each grade and for each unit of the entire song.
[0038]
Next, processing of the performance self-study apparatus will be described with reference to a flowchart. FIG. 4 is a main flowchart. In step S1, the personal computer 1 is initialized, including clearing a VRAM for displaying an image on the display 14 and a timer. In step S2, a practice song is selected. For example, a list of practice songs is displayed on the display 14, and the performer selects a song using the keyboard 12 or the mouse 13. If the song is selected, the process proceeds to step S3, where the unit is designated, that is, the lesson part of the song is designated.
[0039]
The unit designation designates which part of the performance data of the selected tune is to be practiced. A lesson menu based on the performance data is displayed on the display 14, and the unit to be practiced is specified there. Although the unit can be automatically specified according to the data described in the performance data, it can also be manually performed using an input device such as the mouse 13. An example of a lesson menu in which units are set is shown in FIG.
[0040]
In step S4, a lesson is started. The lesson may be started automatically or manually using the keyboard 12 or mouse 13. In step S5, a key pressing instruction generated according to the performance data is displayed on the display 14. A display example of the key pressing instruction will be described later with reference to FIG.
[0041]
In step S6, a musical sound included in the performance data, that is, an accompaniment sound or a metronome sound is reproduced. The reproduced sound can be generated using the sound source device 24 or the sound system 22 of the keyboard instrument 2. In step S 7, the performance results (key on number, key on time, key off time, velocity) by the performer are loaded into the personal computer 1. This is for grade determination. The performance results fetched into the personal computer main body 1 are written in a storage device such as a RAM. The pitch of the performance result is compared with the performance data one by one. When the instruction pitch of the performance data matches the pitch of the performance result, the reproduction of the performance data proceeds and the performance instruction proceeds. If the two do not match, the reproduction of the performance data does not proceed. A performance result that does not match the pitch is overwritten and deleted when a performance result that matches the pitch is fetched. Steps S5 to S7 are performed by timer interrupt processing.
[0042]
In step S8, it is determined whether or not the lesson is completed. When all the performance data of the designated unit has been played, that is, when the data end is reached, step S8 becomes affirmative and the process proceeds to step S9. If the lesson has not ended, the process proceeds to step S5.
[0043]
In step S9, grade determination is performed. In the grade determination, the performance result read in step S7, that is, the actual key press result by the performer is compared with the performance data, and the grade is determined based on the degree of coincidence. The comparison contents are key-on time, key-off time, and velocity. Since only performance results in which the indicated pitch matches the pitch are stored, the pitch is not included in the grade determination. However, if it is played at a pitch that is not specified, it is counted as a miss-touch and compared with the acceptance standard number of times and reflected in the grade. Based on these comparison results, tempo evaluation, on-timing evaluation, off-timing evaluation, rhythm evaluation, sound volume evaluation, and mistouch evaluation are individually performed, and the ranks S to D are determined based on these comprehensive determinations. These evaluation items are examples, and may be evaluated more finely, or evaluation may be performed with a smaller number of items.
[0044]
In step S10, the grade is displayed. The rank is displayed on the lesson menu, and the overall evaluation obtained by integrating the individual evaluations can be superimposed on the key pressing instruction display using a graph separately from the rank display. In step S11, it is determined whether or not the acceptance criterion has been reached for the unit as a result of the result determination. If the acceptance standard is reached, the process proceeds to step S3 to set the next unit to be played. If it passes, the process proceeds to step S12 to determine whether or not to continue the practice. If practice continues, it will progress to step S3. On the other hand, in the case of failure, the process proceeds to step S13 to determine whether or not to continue the practice. Judgment of continuing the practice can be made based on whether or not the player has given an instruction to continue the practice using the keyboard 12 or the like.
[0045]
FIG. 5 is a diagram showing an example of performance data. This performance data is compared with the performance result by determining the progress of the key pressing instruction for each key press and determining the grade at the end of the performance of the designated portion. In the figure, note numbers, sample key-on time, sample key-off time, and sample velocity are set for the instructional sounds A1 to AN arranged in the order of performance.
[0046]
FIG. 6 is a diagram illustrating an example of performance results stored in the storage device. The input key on time, the input key off time, and the input velocity are written in the storage device with respect to the performance musical sounds B1 to BN for the instruction musical sounds A1 to AN. The performance results are written in real time one by one. When played with a pitch different from the sample note number, it is counted as a miss touch, and the number of miss touches (input mistakes) is written for each musical tone.
[0047]
FIG. 7 is a diagram illustrating an example of sub-evaluation that serves as a basis for comprehensive evaluation. In the figure, the tempo rate is defined as the time from the sample key-on time of the instruction musical sound A1 to the sample key-off time of the instruction musical sound AN (which may be the sample key-on time) and the input key-on time of the musical performance sound B1 to the performance musical sound BN. This is the value of the ratio of the time until the input key-off time (may be key input-on time). That is, it is an indicator of how much extra time it takes or how short it actually takes compared to the sample performance time.
[0048]
The expansion key on time and expansion key off time are values obtained by dividing the input key on time and the input key off time by the tempo rate, respectively. That is, the input key on time and the input key off time are expanded or contracted according to the tempo rate so that the key on time based on the performance data can be compared with the actual key on time.
[0049]
The input-on evaluation is an evaluation according to the difference between the sample key-on time and the input key-on time, and the input-off evaluation is an evaluation according to the difference between the sample key-off time and the input key-off time. An evaluation of 1 to 5 is made according to the magnitude of the difference.
[0050]
The input step evaluation is an evaluation determined by comparing the time from the previous musical tone to the key-on time with respect to the sample key-on time and the input key-on time. By this input step evaluation, it is possible to determine whether or not the space between musical sounds is good.
[0051]
The input gate evaluation is a value evaluated by comparing the key-on time, that is, the time from the input key-on time to the input key-off time, with the time from the sample key-on time to the sample key-on time.
[0052]
In addition, the extension on evaluation, the extension off evaluation, the extension step evaluation, and the extension gate evaluation were respectively expanded and evaluated in the same manner as the input on evaluation, the input off evaluation, the input step evaluation, and the input gate evaluation. Value.
[0053]
FIG. 8 is a diagram illustrating an example of comprehensive evaluation based on the sub-evaluation. In the comprehensive evaluation, tempo, on timing, off timing, rhythm, volume, and mistouch are comprehensively determined for all musical tone numbers. The tempo evaluation is given higher as the tempo rate is closer to “1”. The on-timing evaluation is a value obtained by deciding the highest value for each musical tone number from among the input on-evaluation, input step evaluation, expansion / contraction on evaluation, and expansion / contraction step evaluation for the musical tone numbers B1 to BN. .
[0054]
Similarly, in the off timing evaluation, the highest value among the input off evaluation, the input gate evaluation, the expansion / contraction off evaluation, and the expansion / contraction gate evaluation is determined for each musical number, and the maximum values are averaged. Value.
[0055]
In addition, the rhythm evaluation is an evaluation that increases as the number of stretch-on evaluations that have passed the acceptance standard increases. Further, the volume evaluation is an evaluation that increases as the difference between the sample velocity and the input velocity is small, and the mistouch evaluation is an evaluation that increases as the number of mistouches decreases.
[0056]
Although the above-mentioned evaluation was made into five grades, the classification of evaluation is not restricted to this, For example, it may be evaluated with a 100-point perfect score, and it is good also as three-step evaluation.
[0057]
FIG. 9 is a diagram in which the comprehensive evaluation is displayed in a graph on the key pressing instruction display. In the figure, a keyboard figure is displayed at the bottom of the screen. Note that a keyboard figure K can be displayed at the top and bottom of the screen to make it easy to see which key on the keyboard corresponds to the key pressing instruction. A rectangular key pressing instruction mark M having a long side representing the length of a musical tone and a short side of the key width of the keyboard figure K is displayed above the keyboard figure K. One key pressing instruction mark M corresponds to one musical tone. Here, a key pressing instruction mark for two measures is displayed. The upper and lower sides of the screen are the time axis, and the key press instruction mark M close to the lower keyboard figure K is an instruction of a musical sound to be played early. The key pressing instruction mark M moves downward in order, and the key corresponding to the key pressing instruction mark M whose lower end reaches the lower keyboard figure K is the key to be played next. The scrolling of the key pressing instruction mark M is executed when the performer presses the key having the correct pitch. However, the scroll timing is not limited to this. For example, the key pressing instruction mark M may be scrolled by one when releasing the key.
[0058]
As the display of the key pressing instruction, the one described in the specification of Japanese Patent Application No. 2001-352206 relating to the application of the present applicant can be applied. The display of the key pressing instruction is not limited to scrolling, but may be an instruction for the entire music at the same time, or the display may be changed by switching the screen. Further, when scrolling the key pressing instruction, the speed is arbitrary and may follow the tempo of the music.
[0059]
The comprehensive evaluation G is also displayed on the screen on which the key pressing instruction mark M is displayed. As shown in this figure, the comprehensive evaluation is preferably performed so that the skill of the practitioner can be intuitively understood by the outline shape of the polygonal graph and the shift of the center of gravity, but the type of graph is not limited to this. For example, even a bar graph can easily recognize which element is the strength or weakness of the trainee.
[0060]
The graph display is not limited to the comprehensive evaluation. For example, an arbitrary item for comprehensive evaluation can be selected, and the evaluation for each musical tone can be displayed as a time-series line graph or the like for the item. As a result, it is possible to recognize a problem portion in the progress of the performance. It should be noted that the items to be displayed may be selected and designated with the mouse 13 or the like on the displayed comprehensive evaluation graph. The graph display may be displayed in a space where the key pressing instruction mark M is not described, or may be performed on a different screen independent of the key pressing instruction display.
[0061]
FIG. 1 is a block diagram showing main functions of the performance self-study apparatus. In the figure, the performance data storage unit 3 stores performance data of practice songs for key pressing instructions. The key pressing instruction creating unit 4 creates information for key pressing instruction display according to the performance data. The key press detection unit 5 detects a key on number, a key on time, a key off time, and a velocity based on a sensor or switch sensing signal provided on the keyboard 21. When the key-on number matches the note number of the performance data, the key-pressing instruction creating unit 4 reads the performance data relating to the next musical tone and updates the information on the key-pressing instruction display. Information for displaying the key press instruction is output to the display 14 and displayed.
[0062]
The key pressing sound storage unit 6 captures and stores the output data of the key pressing detection unit 5. The grade determination unit 7 evaluates the performance by comparing the key depression information stored in the key depression sound storage unit 6 with the performance data. The gradebook creation unit 8 creates a chart such as a graph based on the performance evaluation. The created chart is displayed on the display 14 together with a key depression instruction or individually.
[0063]
The grade judging unit 7 does not judge the grade only by not performing at the pitch as instructed (being able to perform according to the pitch is a prerequisite for judging the grade), but the overall performance time, Information relating to performance timing, such as key-on time, key-off time, key-pressing time (gate time), and “between” musical notes, ie, step time, is mainly evaluated by comparing sample data with input data. Therefore, the skill of the performer can be evaluated in detail, and the rank can be determined based on this evaluation. As a result, it is possible to move up to a higher rank when the practitioner is truly capable.
[0064]
As described above, in the present embodiment, the skill of the performer can be specifically determined. And based on this determination result, the reference | standard of evaluation can be changed. For example, the grades (1) to (5) have different evaluation criteria. If this grade evaluation standard is linked to the evaluation result obtained by the above-described evaluation method, the grade is appropriate for any player. Therefore, if you practice step by step from a lower grade, you can increase your skill without difficulty.
[0065]
【The invention's effect】
As is clear from the above description, according to the inventions of claims 1 to 6, performance evaluation is performed particularly in comparison with information on the timing of performance, so that a sense of rhythm and a detailed understanding of the music are detailed. It is possible to determine the skill of the performer that is not known from the evaluation of whether or not the performance was possible according to the pitch.
[0066]
According to the invention of claim 4, it is possible to determine the unit of the entire performance. According to invention of Claim 5, 6, evaluation can be recognized visually. In particular, according to the sixth aspect of the present invention, performance evaluation can be viewed in association with the performance instruction display.
[0067]
As described above, according to the present invention, the skill of the performer can be specifically determined. Therefore, when the grade of practice is increased, an appropriate grade evaluation standard is set for each grade by linking with the determination result. can do.
