Technical Field

The invention relates to the technical field of artificial intelligence electronics, in particular to an intelligent metronome and a musical instrument learning assisting method.

Background

The existing metronomes in the market are mainly mechanical metronomes and electronic metronomes, the functions of which are compared with each other, and the metronomes are mechanical, electric or electronic devices capable of giving out stable beats at various speeds. The most basic function is simply to determine the speed. The user uses it to determine the exact tempo of the music being played, thereby gradually creating a sense of sharp tempo, but not being able to guide and correct the learning of the musical instrument.

At the present stage, many children learn musical instruments such as pianos, and in the learning process, most parents do not have the ability of guiding the children to learn the musical instruments, so that the device and the method can supervise and guide the children by recording the playing sound, frequency, rhythm, fingering and the like in the learning process of the children, and guide the children on site by images in a mode of teaching through lively activities, so as to record the learning process of the children.
