A gamelan instrument is a traditional musical ensemble from Indonesia, typically made up of a variety of instruments such as metallophones, xylophones, drums, and gongs. The GONG is a percussion instrument that is often used in gamelan music, and is made of metal or other hard materials. It produces a deep, resonant sound when struck with a mallet. Gongs are an integral part of the gamelan ensemble, and are used to signal transitions between sections of the music.
