The "horse gong" used by the frenetically dancing drummers in a hua gu team has to have a crisp, short sound. There are convex gongs with no navel, hat-shaped gongs for chanting Buddhist scriptures, and gongs with a completely flat platter that are used by town criers to get attention. Not only do the shapes differ, but the tones must also be adjusted according to the purpose of the gong.
其他像鑼面帶有弧度而無鑼臍的響盞、沙鑼，誦經用的帽子型雲鑼，或是傳達信息鑼面平平的馬鑼，都有不同的角色功能，在音色上也需作不同調整。
