Music and dance

Slit drums are indigenous Austronesian musical instruments invented and used by Southeast Asian-Austronesian and Oceanic-Austronesian ethnic groups.

Gong ensembles are also a common musical heritage of Island Southeast Asia. The casting of gong instruments is believed to have originated from the Bronze Age cultures of Mainland Southeast Asia. It spread to the Austronesian islands initially through trade as prestige goods. However, mainland Asian gongs were never used in ensembles; the innovation of using gong sets is uniquely Austronesian. Gong ensembles are found in western Malayo-Polynesian groups, though they never penetrated much further east. There are roughly two gong ensemble traditions among Austronesians, which also produced gongs in ancient times.

In western Island Southeast Asia, these traditions are collectively known as gamelan, being centred on the island of Java in Indonesia. They include the celempung of the Malay Peninsula, talempung of northern Sumatra, caklempung of central Sumatra, chalempung of southern Sumatra, bonang of Java, kromong of western Kalimantan, engkromong of Sarawak, and trompong of western Nusa Tenggara.

In eastern Island Southeast Asia, these traditions are known as kulintang and are centred in Mindanao and the Sulu archipelago of the southern Philippines. They include the kulintangan of Sabah and Palawan, kolintang of northern Sulawesi, kulintang of Halmahera and Timor, and totobuang of the southern Maluku Islands.
