Classical music generally refers to the art music of the Western world, considered to be distinct from Western folk music or popular music traditions. It is sometimes distinguished as Western classical music, as the term "classical music" also applies to non-Western art music. Classical music is often characterized by formality and complexity in its musical form and harmonic organization, particularly with the use of polyphony.
Gamelan (ˈgæməlæn) (ꦒꦩꦼꦭꦤ꧀, ᮌᮙᮨᮜᮔ᮪, ᬕᬫᭂᬮᬦ᭄) is the traditional ensemble music of the Javanese, Sundanese, and Balinese peoples of Indonesia, made up predominantly of percussive instruments. The most common instruments used are metallophones played by mallets and a set of hand-played drums called kendang, which register the beat. The kemanak (a banana-shaped idiophone) and gangsa (another metallophone) are commonly used gamelan instruments in Bali.
