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 gamels, meaning "to strike or hammer", and the suffix an, which makes the root a collective noun.
