A gamelan is a traditional musical ensemble from Indonesia, typically from the islands of Java and Bali, featuring a variety of instruments such as metallophones, xylophones, kendang (drums) and gongs; bamboo flutes, bowed and plucked strings. Vocalists may also be included. For most Indonesians, gamelan music is an integral part of Indonesian culture. The term refers more to the set of instruments than to the players of those instruments. A gamelan is a set of instruments as a distinct entity, built and tuned to stay together – instruments from different gamelan are generally not interchangeable.
