In Bali, an ensemble of angklung is called gamelan angklung (anklung). While the ensemble gets its name from the bamboo shakers, these days most compositions for Gamelan Angklung do not use them. An ensemble of mostly bronze metallophones is used instead.
While the instrumentation of gamelan angklung is similar to gamelan gong kebyar, it has several critical differences. First, the instruments are tuned to a 5-tone slendro scale, though actually most ensembles use a four-tone mode of the five-tone scale (an exception would be five-tone angklung from the north of Bali.) Secondly, whereas many of the instruments in gong kebyar span multiple octaves of its pentatonic scale, gamelan angklung instruments only contain one octave, though some five-tone ensembles have roughly an octave and a half. The instruments are often considerably smaller, and hence more portable when used in cremation rituals. The musicians often play in a procession as the funeral bier is carried from the cemetery to the cremation site, in addition to playing music to accompany the ceremony.
The structure of the music is similar to gong kebyar. Jublag and jegog carry the basic melody, which is elaborated by gangsa, reyong, ceng-ceng, drum, and flute. A medium sized gong, called kempur, is generally used to punctuate a song's major sections. And although most older compositions generally do not employ gong kebyar's more ostentatious virtuosity and showmanship, many Balinese composers have created kebyar-style works for gamelan angklung, often featuring dance.
