Cymbals are suitable for middle-class children. In the design of percussion activities, we often use some kind of game form, and begin to get in touch with relatively complex musical instruments, such as the double-ring drum that needs to distinguish the pitch, the snare drum that needs certain playing skills, and the lobby drum. Cooperative performances have also increased, and a variety of musical instruments have gradually appeared in the music played, playing different rhythms at the same time.
