Gamelan gong kebyar is a style or genre of Balinese gamelan music. Kebyar means "the process of flowering",[citation needed] and refers to the explosive changes in tempo and dynamics characteristic of the style. It is the most popular form of gamelan in Bali, and its best known musical export.[citation needed] Gong kebyar music is based on a five-tone scale called pelog selisir (tones 1, 2, 3, 5, and 6 of the 7-tone pelog scale), and is characterized by brilliant sounds, syncopations, sudden and gradual changes in sound colour, dynamics, tempo and articulation, and complex, complementary interlocking melodic and rhythmic patterns called kotekan.
