Answer:
Contrary to appearances, the Balinese and Javanese gamelans have quite different ensembles and distinct musical styles. When the new playing and dance style known as kebyar emerged at the start of this century, the Balinese gamelan underwent a transformation. Compared to the more polite and dignified Central Java music, this is significantly more jubilant. A more recent gamelan genre comes from Balinese music.
Western influences are infused into Balinese gamelan to create it. It is a more approachable and varied type of gamelan.
Javanese gamelan is a gentler, lower-pitched gamelan style that supports vocalists and rhythmic patterns. It is more traditional and well suited to palaces and temples. Balinese gamelan is essentially similar to the Javanese but, in fact, the ensembles are different and the music pronouncedly so.
