Gordang sambilan is a kendang (Indonesian version of drum) musical instrument originating from North Sumatra, Indonesia.

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.

The terms used by the people of Gunung Tua – Muarasoro, the names of the drums in order from the smallest to the largest are as follows: eneng-eneng, dang-kudang, paniga and jangat.

The goal is to ask for help from ancestral spirits, to overcome difficulties that are currently befalling the community, such as infectious diseases.
