A kind of intelligent piano performance evaluation method and system

Abstract

The invention discloses a piano playing smart evaluation method. The method includes collecting MIDI audio digital signals of a user and converting the signals to playing data; matching a user playingtime sequence with a master playing time sequence in a time line; performing intonation judgment on note groups in user playing based on note groups in master playing; performing pace judgment on note relative duration of user playing based on note relative duration of master playing; calculating the relative speed of user playing speed based on master playing speed and performing speed judgment;performing power judgment on note power of user playing based on note power of master playing; performing comprehensive evaluation on playing intonation, playing pace, playing speed and playing power; marking the comprehensive evaluation result on a stave on a smart terminal. The invention also provides a piano playing smart evaluation system. The invention has beneficial effects that accurate, objective and multi-aspect comparison is made on exact user sound source files with professional playing tunes and user playing level is reflected truly.

Description

technical field [0001] The invention relates to the technical field of musical instruments, in particular to an intelligent piano performance evaluation method and system. Background technique [0002] Traditional piano learning needs to be guided by professional teachers from the enlightenment stage. According to the step-by-step textbooks, the mistakes made by piano learners during the performance process are corrected at any time. Teacher's real-time guidance and repeated wrong practice, resulting in waste of time and low efficiency. [0003] In the prior art, music scores are usually identified through MIDI so that beginners are provided with an entry-level playing and learning method by corresponding piano button indicators. However, in the real piano music practice process, learners need to master music notation, Rhythm, speed, strength and expressiveness can be performed more perfectly. [0004] At present, there is an evaluation method that uses a metronome to fix ...

AI Technical Summary

Problems solved by technology

Because what is played with the metronome is not music but machinery, and it is impossible to evaluate the user's speed, rhythm, and emotional processing of the music, only to correct wrong sounds

In addition, there are also sound recognition methods combined with the DTW algorithm for performance evaluation of music scores, but the current theoretical value may be higher than the practical value. The accuracy rate is greatly reduced, which seriously affects the actual performance evaluation results

The calculation dimensions of the existing evaluation methods and the comprehensive score lack accuracy and objectivity, and cannot truly reflect the user's performance level
