Please tell me what kind of sound can be called music.

A regular, pleasant, beautiful and moving sound is called music.

In Confucian music theory, sound, sound and music are three different concepts. The difference between sound and sound is that sound has rhythm and tone, but sound doesn't. It is usually called noise and sound is called music. Understanding music is an important symbol that distinguishes people from animals. Music usually refers to those beautiful sounds. The waveform of music is regular.

The "music" that people said in the Western Zhou Dynasty, that is, music and dance, refers to different music and dance actions taken in coordination with different etiquette. Etiquette is used to distinguish between high and low, and to judge right and wrong. Music and dance are used to ease up and down and integrate people's hearts. The system of rites and music in Zhou Dynasty is a combination of politics and art education, emphasizing the mutual cooperation and support of rites and music in order to fully consolidate the rule and reconcile the people's hearts.
