Time.
Step S304: obtain the initial time playing each target note in each target trifle of the music score of Chinese operas
If this music score of Chinese operas is that each note is played successively, then when this target trifle is played each target note initial
Quarter can be obtained by following formula
If this music score of Chinese operas there may be the situation playing at least two note simultaneously, then need the concrete of each note is risen
Moment beginning obtains.
Therefore, by above-mentioned process, target is played sequence and is included: the target duration of each target trifle, target trifle
Initial time, the target duration of target note and the initial time of target note, above-mentioned numerical value is according to the order played successively
The target music score of Chinese operas is demarcated.
Above-mentioned step does not has strict order.The target of this generation music score of Chinese operas is played sequence and can be drilled by gathering teacher
The real-time condition playing this music score of Chinese operas obtains, it is also possible to by obtaining in the audio data that collection is published, it is also possible to set by the music score of Chinese operas
Fixed.Such as, set and start the initial time of first object note of trifle as 0, the most in order according to the length of the most each note
Short, beats etc. obtain each value above-mentioned in the music score of Chinese operas, generate target and play sequence.
Concrete, the user of the current trifle obtaining the music score of Chinese operas of step S101 plays the process of sequence in real time and specifically includes:
Obtain user and play initial time and the finish time of each actual note.Therefore, these continuous print note informations
Form user and play sequence in real time.
Such as, for piano, then the initial time playing actual note is the moment that key is pressed, and finish time is key
The moment lifted.
Concrete, as shown in Figure 4, the process of step S102 specifically includes:
Step S401: gather the actual initial time playing current trifle.
The actual initial time of the current trifle of this performance, can determine according to the progress of metronomic rhythm and performance.
Concrete, the definition of metronomic " rhythm " or " speed " is the beat number played per minute.The music score of Chinese operas is made up of some trifles, often
Individual trifle has a beat.The definition of trifle beat is: the total umber of beats of trifle/often clap corresponding note classification.One the most fixed
The music score of Chinese operas of justice, it is possible to calculate each trifle starting position relatively with beat number and the beat number of this trifle starting trifle.Institute
With, if it is known that the beginning trifle position of the music score of Chinese operas, play the moment starting trifle, by the speed of metronome, it is possible to push away
Calculate the initial time of each trifle.
Step S402: according to the trifle played after the actual initial time of current trifle, current trifle and current trifle
Target play sequence, the target of the trifle after revising current trifle and current trifle plays each target of performance in sequence
The initial time of note, obtains target and plays Orders Corrected.
When user strikes up current trifle, this actual initial time can be obtained, according to current trifle and current trifle
The target of trifle afterwards plays the target duration of the target note in sequence can revise the initial of each target note of performance
Moment.

Step 403: gather actual initial time and the finish time of the actual note of performance one in current trifle, and by drilling
Initial time and the finish time of playing this actual note obtain the actual duration playing this actual note.
The actual duration playing this actual note is actual initial time and the difference of finish time playing this actual note.
Step S404: in the first range of tolerable variance, it is thus achieved that immediate with the actual initial time playing an actual note
Target performance Orders Corrected is played at least one target note that the initial time of a target note is corresponding.
Wherein, the first range of tolerable variance is-0.7s～+0.7s.Wherein, the first tolerance is that the reality playing an actual note rises
Moment beginning and immediate target play the difference of the initial time playing a target note in Orders Corrected.Such as, one is played
The initial time of actual note is 50 points of 30s, and target immediate with it is played and played rising of a target note in Orders Corrected
Moment beginning is 50 points of 30.5s, then the first tolerance is+0.5s, and the initial time of this actual note of performance one is positioned at the first tolerance model
In enclosing.

Range of tolerable variance is-0.7s～+0.7s.The first range of tolerable variance that normal mode is corresponding is-0.5s～+0.5s.Harsh pattern is corresponding
The first range of tolerable variance be-0.3s～+0.3s.
It is the situation of at least two note owing to there may be same initial time and need to playing, therefore, this step can obtain
Obtain all notes in the first range of tolerable variance.
If not having the initial time of any target note to match in this first range of tolerable variance, then carry out step
S408, this misrepresentation is note mistake.If additionally, not finding actual note, then this misrepresentation in the first range of tolerable variance
Omit for note.Concrete, if playing Orders Corrected with the immediate target of actual initial time playing an actual note
Within 0.25 second, play this actual note before the initial time of middle performance one target note, then records appraisal is musical notes in advance；
Within 0.25 second after this moment, play this actual note, then records appraisal is for postponing musical notes.
Step S405: compare this actual note and at least one this target note.
All target notes in this actual note and the first range of tolerable variance are compared.If actual note has two, then
Compare the most one by one.
If actual note mates with target note, it is i.e. identical note, as being all 5, then carries out step S406.
If this actual note does not mates with this target note arbitrary, then carry out step S408.Such as, actual note is 5, and
All notes in first range of tolerable variance do not have 5, then this performance mistake, belongs to the situation of note mistake.
Step S406: if this actual note mates with this target note arbitrary, then in the second range of tolerable variance, by this reality
The actual duration of note compares with the target duration of this target note mated.If coupling, carry out step S407, if not
Coupling then carries out step S408.
If actual note mates with target note, it is i.e. identical note, as being all 5, then, compares duration.
Wherein, the second range of tolerable variance is-15%～+15%.Wherein,
Such as, the actual duration of actual note is 2s, and the target duration of the target note of coupling is 2.5s, then the second tolerance isBeyond the second range of tolerable variance.
Preferably, user can select before performance: loose, normal and harsh pattern, then loose pattern corresponding second
Range of tolerable variance is-15%～+15%.The second range of tolerable variance that normal mode is corresponding is-10%～+10%.Harsh pattern is corresponding
The second range of tolerable variance be-5%～+5%.
Concrete, even if playing actual duration compared with playing target duration in the second range of tolerable variance
In, if <-10%, recordable to be evaluated as note duration too short for the second tolerance；If the second tolerance > 10%, recordable it is evaluated as note
Duration is long.
Step S407: if the actual duration of this actual note is mated with the target duration of this target note mated, then comment
This actual note of valency is played correct.
Step S408: evaluate this actual note and play mistake.
If in the second range of tolerable variance, this actual duration is mated with target duration, and as being all 1s, then this actual note is played
Correctly.Can be marked for playing correct actual note, it is to avoid repeat to compare.
