Gordang Sambilan is a traditional art form of the Batak Mandailing ethnic group. The term "Gordang" refers to a drum or bedug, while "Sambilan" means nine. As the name suggests, Gordang Sambilan consists of nine drums of varying lengths and diameters, each producing a distinct pitch. Typically, the ensemble is played by six performers. The smallest drums, numbered 1 and 2, are known as taba-taba; drum 3 is called tepe-tepe; drum 4 is kudong-kudong; drum 5 is kudong-kudong nabalik; drum 6 is pasilion; and drums 7, 8, and 9 are referred to as jangat.
Originally, Gordang Sambilan was performed only during sacred and ceremonial events. However, with the evolution of social and cultural practices, it is now commonly featured in various occasions such as weddings, guest welcoming ceremonies, and national holidays. Recognized as part of Indonesia’s intangible cultural heritage, Gordang Sambilan has even been performed at the Presidential Palace, showcasing its cultural significance on a national stage. [2
