The origin of music in human society can be traced back to the very ancient prehistoric times. Before humans had language, they already knew how to use the pitch, strength, etc. of sounds to express their thoughts and feelings. With the development of human labor, chants to unify the rhythm of labor and shouts to convey information to each other gradually emerged. This is the most primitive prototype of music. When people celebrate harvests and share the fruits of labor, they often beat stone and wooden tools to express their feelings. Joy, joy, this is the prototype of the original musical instrument.
