An artificial intelligence piano grade test equipment

technical field

The utility model relates to the technical field of piano grade examination and evaluation, in particular to an artificial intelligence piano grade examination and evaluation device.

Background technique

The piano is a keyboard instrument derived from Western classical instruments. It consists of 88 keys and a metal string soundboard. The player presses the keys on the keyboard to move the small mallet inside the piano, and then strikes the steel strings to make sounds. The piano is known as the king of musical instruments because of its wide range and beautiful timbre. With the improvement of people's living standards, more and more people are learning piano performance, and more and more amateur piano learners take the piano grade test. The number has also increased, and at the same time, higher requirements have been placed on professional grading teachers, and the work pressure of professional grading teachers will also increase. In addition, the efficiency of students' piano grading assessment is low, and the grading results are easily affected by the personal subjective factors of professional grading teachers, resulting in the inability to give an objective evaluation based on the performance of the performance. Several kinds of music scores are used as samples first, and then the scores played by candidates in real time are used as samples, deep learning network training is carried out, different levels are marked, the weight matrix and offset parameter values are output, and finally the judgment rules and devices for machine learning are obtained.

However, when the prior art is actually used, because the artificial intelligence piano grade testing and evaluation equipment is relatively sophisticated, it is easily damaged during transportation or use, resulting in inaccurate evaluations.
