Gordang sambilan
Gordang sambilan is a kendang (Indonesian version of drum) musical instrument originating from North Sumatra, Indonesia.[1] Gordang sambilan consists of nine relatively large and long drums (drum chime) made of ingul wood and played by four people. The size and length of the nine drums are stratified, starting from the largest to the smallest.
For Mandailing people, especially in the past, gordang sambilan was a very important sacred traditional music. Gordang sambilan is seen as sacred because it is believed to have supernatural powers to summon ancestral spirits to provide help through a medium or shaman called Sibaso.[2]
Performance
Gordang sambilan is used for ceremonies to summon ancestral spirits if help is needed. The ceremony is called paturuan Sibaso (summoning the spirit to possess / possess Sibaso medium). The goal is to ask for help from ancestral spirits, to overcome difficulties that are currently befalling the community, such as infectious diseases. Gordang sambilan is also used for ceremonies asking for rain or to stop the rain that has fallen for too long and causes damage, meaning that agricultural activities and community life can be restored. Apart from that, it is also used for a wedding ceremony called Orja Godang Markaroan Boru and for a funeral ceremony called Orja Mambulungi.[3]
Today, the gordang sambilan is still used by the Mandailing people as a sacred traditional musical instrument.[1][4]
