Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
The embodiment of the invention discloses a performance evaluation method. The method of the embodiment of the invention can take the measure of the music score as the minimum unit of discrimination. The method provided by the embodiment of the invention can be used for learning of musical instruments such as pianos, electronic organs and the like. Fig. 1 is a flowchart of a performance evaluation method according to an embodiment of the present invention. The performance evaluation method comprises the following specific processes:
step S101: a user real-time performance sequence of a current bar of a music score is acquired.
Preferably, in order to facilitate the acquisition of the real-time playing sequence of the user, a countdown step may be provided, for example, 4 beats may be started to let the user adapt to the rhythm, and the playing may be started when the countdown is 0. More preferably, the reciprocal may be sounded, and the reciprocal number may be displayed on a screen.
Preferably, during step S101, if the user selects to play the accompanying sound, the method may play the accompanying sound at the same time.
Preferably, in order to facilitate the user to play accurately, the accompanying sound of the beat or the current bar can be continuously played for the user to refer to.
Step S102: the user real-time performance sequence of the current bar is matched with the target performance sequence of the current bar.
The user real-time playing sequence is the playing information which is collected in sequence in the user real-time playing process. The target performance series is standard performance information determined from a music score, and can be generated from the music score by a computer.
Preferably, if the user selects to play the music score of only one hand, only the notes played by the one hand in the target performance sequence are matched in the matching process of step S102.
Step S103: the accuracy of the performance of the user of the current bar is evaluated based on the matching result.
The evaluation of the performance includes: note error, note missing, note played ahead, note played behind, note played late, note too short or too long. For example, in the case of a piano, each error corresponds to a key error, a missing key, a key depression in advance, a key depression delay, a key depression state with a too short duration or a too long duration.
Wherein the note error indicates: a note is played that is not required to be played at the current position of the score.
Note missing indicates: there is no note played that is required to be played at the current position of the score.
Pre-performance note representation: some time earlier than the moment the score requires to play the note.
Delayed performance note representation: later than the moment at which the score requires the note to be played.
Too short a note duration indicates: the duration of the note is shorter than the duration required for the score.
An excessively long note duration indicates: the duration of playing the note is longer than the duration required for the score.
With the performance evaluation method of the embodiment of the present invention, the performance is accurately evaluated by matching the user real-time performance sequence of the current bar with the target performance sequence of the current bar.
For the above errors, corresponding scoring can be performed, for example, a full score is 100 points, a note missing is 10 points, a note is 5 points are deducted in advance or delayed in playing, a note is too short in duration or too long in duration is deducted by 2 points, and finally, a score of playing is obtained according to the above scoring rule to evaluate the playing.
Preferably, with the method of the embodiment of the present invention, if the performance of the bar is completely correct, the user can continue to perform the next bar; if the measure is played wrongly, the user can play the measure again without continuing to play the next measure; or the user may replay the wrong measure after all measures have been played.
Preferably, as shown in fig. 2, before the step of acquiring the user real-time performance sequence of the current bar of the music score, the method further comprises the steps of:
step S201: at least one bar of the music score and the performance tempo are acquired.
The performance can be the performance speed calibrated by the music score, and can also be the performance speed selected by the user.
Step S202: the rhythm of the bar is set at the playing speed.
Step S203: and if a plurality of acquired sections exist, setting a starting section and an ending section.
The purpose of setting the start bar and the end bar is to facilitate the user in selecting a particular portion of the music score to be exercised.
Specifically, the method of the embodiment of the present invention further includes a step of generating a target performance sequence of the music score. Fig. 3 is a schematic diagram illustrating a process of generating a target performance sequence of a music score according to an embodiment of the present invention. The process of generating a target performance sequence of a music score includes:
step S301: target time values T of each target bar of the score are acquirediI is 1, 2, 3, … …, n, n is the number of bars of the curved spectrum.
The target value of each target bar described in the present invention is the time between the start time and the end time of playing the bar.
Step S302: the starting time of each target bar for acquiring the music score is ti
t i = t 1 , i = 1 t 1 + T 1 + ... + T i - 1 , i = 2 , 3 , ... , n .
Step S303: obtaining a target duration for each target note in each target measure of the score m is the number of target notes in each measure.
The target duration of a target note as described in the present invention is the time between the beginning and the end of the playing of the note.
Step S304: acquiring the start time of playing each target note in each target measure of the music score
If the music score is played for each note in turn, the starting time of playing each target note in the target measure can be obtained as follows
s j i = t i , j = 1 ; i = 1 , 2 , ... n t i + S 1 i + S 2 i + ... + S j - 1 i , j = 2 , 3 , ... , m ; i = 1 , 2 , ... n .
If there may be a situation where at least two notes are played simultaneously in the music score, a specific start time of each note needs to be acquired.
Thus, through the above-described procedure, the target performance sequence includes: the target duration of each target measure, the start time of the target measure, the target duration of the target note and the start time of the target note are calibrated in the target score in the order in which they are played.
The steps described above are not in a strict order. The target playing sequence for generating the music score can be obtained by collecting the real-time condition of the teacher playing the music score, can also be obtained by collecting published audio data, and can also be set by the music score. For example, if the start time of the first target note of the beginning bar is set to 0, the values described above in the score are sequentially obtained based on the length, tempo, and the like of each subsequent note, and a target performance sequence is generated.
Specifically, the process of acquiring the user real-time performance sequence of the current bar of the music score at step S101 specifically includes:
the start time and the end time at which the user plays each real note are acquired. Thus, these successive note information form a user real-time playing sequence.
For example, in the case of a piano, the start time of playing an actual note is the time of key depression, and the end time is the time of key lift.
Specifically, as shown in fig. 4, the process of step S102 specifically includes:
step S401: the actual start time of playing the current bar is collected.
The actual starting time of the performance of the current bar may be determined based on the tempo of the metronome and the progress of the performance. Specifically, the "tempo" or "speed" of the metronome is defined as the number of beats played per minute. The music score is composed of a plurality of bars, and each bar has a beat. The definition of the bar beat is: total beats per beat of corresponding note category. A completely defined music score, which can calculate the number of beats of each bar starting position relative to the starting bar and the number of beats of the bar. Therefore, if the position of the starting bar of the music score is known, the time at which the starting bar is played can be deduced from the speed of the metronome.
Step S402: the target performance modified sequence is obtained by modifying the start time of performance of each target note in the target performance sequence of the current bar and the bars following the current bar, based on the actual start time of performance of the current bar, and the target performance sequence of the bars following the current bar.
The actual start time is available when the user begins playing the current measure, and the start time for playing each target note may be modified based on the target durations of the target notes in the target performance sequence for the current measure and measures subsequent to the current measure.
Obtaining the target performance modification sequence facilitates matching the target performance modification sequence with notes to be performed.
Step 403: the actual start time and end time of playing an actual note in the current measure are collected, and the actual duration of playing the actual note is obtained from the start time and end time of playing the actual note.
The actual value of playing the actual note is the difference between the actual start time and the actual end time of playing the actual note.
Step S404: at least one target note corresponding to the starting time of playing a target note in the target playing modified sequence closest to the actual starting time of playing an actual note is obtained within the first tolerance range.
Wherein the first tolerance range is-0.7 s- +0.7 s. Wherein the first tolerance is a difference between an actual onset time of playing an actual note and an onset time of playing a target note in the closest target performance modification sequence. For example, if the start time of playing an actual note is 50 minutes 30s, and the start time of playing a target note in the target performance modification sequence closest thereto is 50 minutes 30.5s, the first tolerance is +0.5s, and the start time of playing an actual note is within the first tolerance range.
Preferably, the user can select, prior to playing: the relaxed, normal and critical modes have a first tolerance range of-0.7 s to +0.7s for the relaxed mode. The first tolerance range corresponding to the normal mode is-0.5 s- +0.5 s. The first tolerance range for the critical mode is-0.3 s- +0.3 s.
Since there may be cases where at least two notes are to be played at the same start time, all notes within the first tolerance range are available in this step.
If the start time of any target note does not match within the first tolerance range, step S408 is performed, and the error is represented as a note error. Furthermore, if the actual note is not found within the first tolerance range, the error is indicated as a note omission. Specifically, if an actual note is played 0.25 seconds before the start time at which a target note is played in the target performance modification sequence closest to the actual start time at which the actual note is played, the recording is evaluated as a pre-played note; when the actual note is played 0.25 seconds after the time, the recording is evaluated as a delayed playing note.
Step S405: comparing the actual note with at least one of the target notes.
The actual note is compared to all target notes within a first tolerance range. If there are two actual notes, each is compared one by one.
If the actual note matches the target note, i.e. the actual note is the same note, if both are 5, step S406 is performed.
If the actual note does not match any of the target notes, step S408 is performed. For example, if the actual note is 5 and all notes within the first tolerance range have no 5, the performance error is the case of a note error.
Step S406: if the actual note matches any of the target notes, the actual duration of the actual note is compared to the target duration of the matching target note within a second tolerance range. If the two signals match, the process proceeds to step S407, and if the two signals do not match, the process proceeds to step S408.
If the actual note matches the target note, i.e., is the same note, e.g., both are 5, then the durations are compared.
Wherein the second tolerance range is-15% to + 15%. Wherein, for example, if the actual duration of the actual note is 2s and the target duration of the matching target note is 2.5s, then the second tolerance isBeyond a second tolerance range.
Preferably, the user can select, prior to playing: the relaxed, normal and critical modes have a second tolerance range of-15% to + 15% for the relaxed mode. The normal mode corresponds to a second tolerance range of-10% to + 10%. The second tolerance range for the severe mode is-5% to + 5%.
Specifically, even if the duration of playing the actual note is within the second tolerance range compared with the duration of playing the target note, if the second tolerance is less than-10%, the duration of the note can be recorded and evaluated to be too short; if the second tolerance is > 10%, the note duration may be recorded as too long.
Step S407: and if the actual duration of the actual note is matched with the target duration of the matched target note, evaluating that the actual note is played correctly.
Step S408: the actual note playing error is evaluated.
If the actual duration matches the target duration within a second tolerance range, e.g., both are 1s, then the actual note is played correctly. The actual notes that are playing correctly can be marked to avoid repeated comparisons.
Step S409: steps S403 to S408 are repeated until all of the actual notes in the user' S real-time performance sequence of the current measure have been matched.
After playing the current bar, the user may continue to play the next bar, completing the matching of all selected bars.
Preferably, in order to facilitate the user to obtain the result of the performance error in real time, the user selects the starting position of the progress cursor at the starting bar when starting the performance. If there is no performance error, the cursor can move in real time with the performance.
Specifically, a music score of a real-time performance is tracked on the music score every beat using a cursor from the first beat of the current bar according to a previously selected tempo.
If the playing of the bar is completely correct, the cursor moves to the note corresponding to the first beat of the next bar;
if any performance error occurs in the performance of the bar, the cursor returns to the start position of the current bar, or the cursor stops moving.
The user can select to stop the performance, replay the erroneous part, and correct the time.
