These four small gongs and one large gong on a stand are known as the kempul and gong siyem. The term 'gamelan' refers to the action ('an') of hammering ('gamel') bronze instruments such as gongs and drums among several other types of instruments with beaters. The bronze instruments play the main melody and are accompanied by softer wind, wood and string instruments. Today gamelan music remains an important part of court and village life in Java. Many sets are kept as royal heirlooms (pusaka) and are played at important ceremonies.
