Yes, the predecessor of the drum can be traced back to the timpani. The timpani is a drum set consisting of a big drum, a small drum and several medium drums. It was originally used by ancient armies to convey signals and command. Over time, the techniques and forms of drumming developed, and players began to use drums of different sizes and tones to create richer musical effects. This gradually evolved into Paigu, which became an independent drum instrument used in various music performances and performances. Paigu usually consists of three or more drums, arranged in a straight line or arc. When played, different tones and rhythms can be produced by different hitting methods.
