Piano playing capability evaluation system based on strong and weak standards

Abstract

The invention discloses a piano visual playing capability evaluation system based on strong and weak standards. The strong standards refer to piano music rhythm and main melody notes. The weak standard refers to optimistic expressive force. The system comprises a man-machine interaction module, a rhythm detection and evaluation module, a main melody note estimation and evaluation module, an expressive force detection and evaluation module and a comprehensive score module. The man-machine interaction module is responsible for music score display and playing audio input; the rhythm detection andevaluation module extracts a note starting point and cuts note segments to obtain a rhythm evaluation score; the main melody note estimation and evaluation module extracts main melody notes of the note segments to obtain main melody evaluation scores; the expressive force detection and evaluation module calculates the emotional distance between the playing audio and the standard audio, and normalizes the emotional distance into an evaluation score; and the comprehensive score evaluation module is used for solving the weighted sum of the scores to realize visual playing capability evaluation.In combination with the characteristics of music appreciation, a strong and weak evaluation standard is set, so that the machine evaluation result is closer to the subjective feeling of people.

Description

technical field [0001] The invention relates to the technical fields of music signal main melody note estimation, musical sense recognition, and signal filter analysis, and in particular to a piano sight-playing ability evaluation system based on strength standards. Background technique [0002] Piano "sight-reading" means that the player gets a new piece of music and reads the score directly according to the information on the sheet music. Unlike playing from memory, "sight-reading" can better reflect the player's piano level and is a very important part of piano learning However, it is actually a link that is relatively neglected in the traditional piano teaching in our country. The main reason is that traditional teaching requires one-on-one guidance from music teachers, but music teachers are expensive and the quality of music teachers is uneven, so it is impossible to accurately judge students' performance ability. Using computer technology to scientifically and object...
