"A gamelan is a musical ensemble from Indonesia, typically from the islands of Bali or Java, featuring a variety of instruments such as metallophones, xylophones, drums and gongs; bamboo flutes, bowed and plucked strings. Vocalists may also be included.

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.

The word "gamelan" comes from the Javanese word "gamel", meaning to strike or hammer, and the suffix "an", which makes the root a collective noun.

In Bali, the Gamelan instruments are all kept together in the balai banjar, a community meeting hall which has a large open space with a roof over top of it with several open sides. The instruments are all kept here together because they believe that all of the instruments belong to the community as a whole and no one person has ownership over an instrument. Not only is this where the instruments are stored, but this is also the practice space for the sekaha (Gamelan orchestra). The open walls allow for the music to flow out into the community where the rest of the people can enjoy it."
