The Angklung got more international attention when Daeng Soetigna, from Bandung, West Java, expanded the angklung notations not only to play traditional pélog or sléndro scales, but also diatonic scale in 1938. Since then, angklung is often played together with other western music instruments in an orchestra. One of the first well-known performances of angklung in an orchestra was during the Bandung Conference in 1955. A few years later, Udjo Ngalagena, a student of Daeng Soetigna, opened his "Saung Angklung" (House of Angklung) in 1966 as centre of its development.
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.
