A kendang or gendang (ꦏꦼꦤ꧀ꦝꦁ, ᮊᮨᮔ᮪ᮓᮀ, ᬓᬾᬦ᭄ᬤᬂ, Tausug/Bajau/Maranao: gandang, Bugis: gendrang and Makassar: gandrang or ganrang) is a two-headed drum used by people from the Indonesian Archipelago. The kendang is one of the primary instruments used in the gamelan ensembles of Javanese, Sundanese, and Balinese music. It is also used in various Kulintang ensembles in Indonesia, Brunei, Malaysia, Singapore, and the Philippines. It is constructed in a variety of ways by different ethnic groups. It is related to the Indian double-headed mridangam drum.
The typical double-sided membrane drums are known throughout Maritime Southeast Asia and India. One of the oldest image of kendang can be found in ancient temples in Indonesia, especially the ninth century Borobudur and Prambanan temple.
Among the Javanese, Sundanese, and Balinese, the kendang has one side larger than the other, with the larger, lower-pitched side usually placed to the right, and are usually placed on stands horizontally and hit with the hands on either side while seated on the floor. Amongst groups like the Balinese, Tausug, and Maranao, both sides are of equal size, and are played on either one or both sides using a combination of hands and/or sticks.
Within Gamelan, the kendang is smaller than the bedug, which is placed inside a frame, hit with a beater, but used less frequently. The kendang usually has the function of keeping the tempo (laya) while changing the density (irama), and signaling some of the transitions (paralihan) to sections and the end of the piece (suwuk).
In the dance or wayang performance, the kendang player will follow the movements of the dancer, and communicate them to the other players in the ensemble. In West Java (Sundanese), kendang are used to keep the tempo of Gamelan Degung. Kendang are also used as main instrument for Jaipongan dances. In another composition called Rampak Kendang, a group of drummers play in harmony.
Among the Makassarese, the Ganrang (kendang) drums have much more importance, with it considered the most sacred of all musical instruments, comparable to gongs in Java.
