A rock gong is a slab of rock that is hit like a drum, and is an example of a lithophone. Examples have been found in Africa, Asia, and Europe. Regional names for the rock gong include kungering, kwerent dutse, gwangalan, kungereng, kongworian, and kuge. These names are all onomatopœic, except for "kuge" which is the Hausa word for a double iron bell and "dawal" which is the Ge`ez word for a church's stone gong.

A lithophone is a musical instrument consisting of a rock or pieces of rock which are struck to produce musical notes. Notes may be sounded in combination or in succession (melody). It is an idiophone comparable to instruments such as the glockenspiel, vibraphone, xylophone and marimba.
