A gangsa is a type of metallophone which is used mainly in Balinese and Javanese Gamelan music in Indonesia. In Balinese gong kebyar styles, there are two types of gangsa typically used: the smaller, higher pitched Template:Transl and the larger Template:Transl. Each instrument consists of several tuned metal bars (either iron or bronze) each placed over an individual resonator. The bars are hit with a wooden Template:Transl, each producing a different pitch. Duration of sound intensity and sound quality factors are generally accomplished by damping the vibration of the bar with the fingers of the free hand. Balinese gong Template:Transl, as with other metallophones in gong Template:Transl ensembles, are played in neighboring pairs with interlocking, rapid-tempo parts that elaborate on the melody of a piece of music (see Kotekan); these pairs are tuned to be dissonant and create certain wavelengths of sympathetic vibrations to create a shimmering tone (see Ombak) that travels long distances. The gangsa is very similar to the old Template:Transl and the Template:Transl.
