The agung is a set of two wide-rimmed, vertically suspended gongs used by the Maguindanao, Maranao, Sama-Bajau and Tausug people of the Philippines as a supportive instrument in kulintang ensembles. The agung is also ubiquitous among other groups found in Palawan, Panay, Mindoro, Mindanao, Sabah, Sulawesi, Sarawak and Kalimantan as an integral part of the agung orchestra.

Kulintang is a modern term for an ancient instrumental form of music composed on a row of small, horizontally laid gongs that function melodically, accompanied by larger, suspended gongs and drums. As part of the larger gong-chime culture of Southeast Asia, kulintang music ensembles have been playing for many centuries in regions of the Southern Philippines, Eastern Malaysia, Eastern Indonesia, Brunei and Timor, Kulintang evolved from a simple native signaling tradition, and developed into its present form with the incorporation of knobbed gongs from Sundanese people in Java Island, Indonesia. Its importance stems from its association with the indigenous cultures that inhabited these islands prior to the influences of Hinduism, Buddhism, Islam, Christianity or the West, making kulintang the most developed tradition of Southeast Asian archaic gong-chime ensembles.
