Modern popular styles include gamelan gong kebyar, dance music which developed during the Dutch occupation and 1950s era joged bumbung, another popular dance style. In Balinese music you can also hear metallophones, gongs and xylophones.
Balinese music can be compared to Javanese music, especially that of the pre-Islamic period. During that time, Javanese tonal systems were imported to Bali.
Balinese gamelan, a form of Indonesian classical music, is louder, swifter and more aggressive than Javanese music. Balinese gamelan also features more archaic instrumentation than modern Javanese gamelans. Balinese instruments include bronze and bambooxylophones. Gongs and a number of gong chimes, are used, such as the solo instrument trompong, and a variety of percussion instruments like cymbals, bells, drums and the anklung (a bamboo rattle). There are two sizes of bamboo flutes, both used in theatrical music, and a rebab (two-stringed spike fiddle).
