The Tanggu (Drum) is known as "Tonggu". During the Qing Dynasty, it was called "Zhanggu". Its skin is normally made of buffalo’s hide. The pitch and tone of the sound produced are not definite. It depends on the strength and which part of the drum skin is being hit.
There are two types of Tanggu: the Xiao Tanggu and the Da Tanggu. The only difference is that the Xiao Tanggu is smaller is size, and thus produces a higher pitch sound.
