Gordang Batak
Gordang Sambilan is a traditional art form of the Batak Mandailing tribe. The term "Gordang" means drum or large percussion instrument, while "Sambilan" means nine. The Gordang Sambilan ensemble consists of nine drums of varying lengths and diameters, each producing a different pitch. Typically, six players perform on these drums, with the smallest drums (1 and 2) played as taba-taba, drum 3 as tepe-tepe, drum 4 as kudong-kudong, drum 5 as kudong-kudong nabalik, drum 6 as pasilion, and drums 7, 8, and 9 as jangat.
Originally, Gordang Sambilan was played only during sacred ceremonies. However, as social culture has evolved, it is now commonly performed at various events such as weddings, welcoming ceremonies, and major celebrations. As a cherished part of Indonesia's cultural heritage, Gordang Sambilan has even been showcased at the presidential palace.
