Bonangs, or gong chimes, are important instruments of the traditional gamelan, the percussion orchestra from Java in Indonesia. The bonang does not usually play the main tune ; instead it plays patterns of quick notes that decorate the melody. Bonangs in java come in two sizes : the bonang panerus, shown here, is the smaller of the two.
