The traditional music of which of these cultures uses the Gong?

The gong is a musical instrument that originated in East Asia and has since found its way to every corner of the globe. Whether you've heard it in classical music, film scores, or traditional Chinese compositions, you probably are already familiar with the sound of a gong. A gong is a percussion instrument formed from a circular metal disc. Gongs are played with mallets, a type of percussion beater with a large, felted head. Gongs are a key instrument in the traditional music of China, Burma, and Indonesia, and they have been a part of Western musical culture since at least the 1700s.
