The instruments are made by the community for the community and the instruments are not owned by individuals but instead are owned by the community. The instruments tunings can vary due to the handmade nature of them. This will create a beating clash called Om Bak. Each Om Bak is unique to a Gamelan.

- Gongan - an 8 beat phrase
- Keteg - A split Gongan, worth half a Gongan; beat 4 in the first Keteg is given the second pitch (2/D) and the second Keteg has the 4th beat given pitch (6/A)
