Sound predates the existence of human beings, and the so-called sound of nature is one of the phenomena in nature. Music is the selective imitation of all kinds of sounds of nature by the human mind
it is the product of culture. Its different styles and forms are obviously limited by various natural conditions. As far as musical instruments are concerned, the ancient chime was made of stone and the drum needed animal skins, all of which were made from natural materials. As for the style of music, although many tunes have been lost, the style varies greatly from the remaining lyrics. The folk songs of the Northern dynasties were rough and open, and the folk songs of the Southern dynasties were exquisite. Kunqu Opera, which originated from the South, was also generous as soon as it spread to the North. Even after entering the court, it maintained a quite vigorous and simple folk composition.
The atmosphere of the court can not completely change the characteristics of music.
