Detection device of piano playing intonation

Abstract

The invention discloses a detection device of piano playing intonation. The detection device of piano playing intonation comprises a sound collecting module, an audio collecting module, a hand shape detecting module, a display module, a contrast evaluation module, a warning module, a central processing unit and a wireless communication module; the audio collecting module is used for receiving an audio electronic signal, the hand shape detecting module is used for detecting movement direction and a movement velocity value of each finger, a bending degree of each finger and pressing force when the piano is playing, and the wireless communication module is used for sending the data to a detection center. The detection device of the piano playing intonation provided by the invention can detect which key is pressed and the press force degree when the piano is played by setting a press sensor module, conduct data acquisition and analysis processing on the sensor module through a data processing device, and accurately recognize the intonation when the piano is played.

Description

technical field [0001] The invention relates to the field of piano playing teaching, in particular to a detection device for piano playing intonation. Background technique [0002] The piano is a keyboard instrument derived from Western classical music. The sound range is wide, from A2 (27.5Hz) to C5 (4186Hz), almost including all the tones in the tone system. The piano is generally used for performances such as solo, ensemble, and accompaniment. It is very convenient for composing and rehearsing music. The player presses the keys on the keyboard, moves the small mallet covered with felt inside the piano, and then strikes the steel strings to produce sound. Because of its wide range and beautiful timbre, the piano is known as the king of musical instruments, and it is also known as the world's three major musical instruments together with the violin and classical guitar. [0003] The piano is composed of nearly ten thousand parts such as keyboard, string column, soundboar...

AI Technical Summary

Problems solved by technology

[0005] In the current piano education and learning process, the most widely used traditional piano (different from electronic pianos, electric pianos, etc.) is a purely mechanical structure device, which cannot collect pitch data during the player's playing process. Comparing and analyzing the performance of the performers, it is impossible to achieve standardized, refined and intelligent digital teaching
