Gambang

A gambang, properly called a gambang kayu ('wooden gambang') is a xylophone-like instrument used among peoples of Indonesia and the southern Philippines in gamelan and kulintang, with wooden bars as opposed to the metallic ones of the more typical metallophones in a gamelan. A largely obsolete instrument, the gambang gangsa, is a similar instrument made with metal bars.
