A kind of intelligent piano and system

Abstract

An intelligent piano and a system, which can realize functions such as staff identification, correction and scoring, timbre replacement and composing, and improve piano learning efficiency. The intelligent piano comprises a piano keyboard (14) provided with keys, an indicator module (13), a first data communication module (11), a key detection module (15), a MIDI data processing module (12), a MIDI synthesizer (16), an audio coder (17), an audio amplifier (18), and a loudspeaker (19). The first data communication module (11) receives and sends music score data and timbre data to the MIDI data processing module (12) and the MIDI synthesizer (16). The MIDI data processing module (12) processes the music score data and sends the processed music score data to the indicator module (13), and the indicator module (13) indicates whether keys at corresponding positions should be pressed or not. The key detection module (15) detects motion signals of the keys and sends the motion signals to the MIDI data processing module (12) for processing. The MIDI synthesizer (16) synthesizes the processed motion signals and the timbre data into audio analog signals, and sends the audio analog signals to the audio coder (17) for coding. The coded signals are amplified by the audio amplifier (18) and are played by the loudspeaker (19).

Description

technical field [0001] The invention belongs to the field of musical instruments, and in particular relates to an intelligent piano and a system having the functions of notation recognition, error correction, impromptu composition, and timbre replacement. Background technique [0002] 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, moves the small mallet inside the piano, and then strikes the steel wire strings to produce sound. The piano is known as the king of musical instruments because of its beautiful sound. With the improvement of people's living standards, more and more people are learning to play the piano. In addition to talent, piano performance also requires face-to-face instruction from a piano teacher. Therefore, it is difficult for students to practice independently without the guidance of a piano teacher. . At present, the existin...

Problems solved by technology

With the improvement of people's living standards, more and more people are learning to play the piano. In addition to talent, piano performance also requires face-to-face instruction from a piano teacher. Therefore, it is difficult for students to practice independently without the guidance of a piano teacher.

At present, the existing fun piano learning machine can not give intuitive prompts to learners through software virtual keys in terms of stave recognition, and the instructions are one-way, and two-way functions (instructions and feedback) cannot be realized.

Afterwards, the following smart piano can realize two-way function, but the music played by sound recognition, and then compare the score data with the score data recognized by the sound. Due to the large error of sound recognition, the error correction error is large.
