It commonly appears in performances by Santal, Munda, and Oraon communities during festivals and rituals. Mandar and Dhol are primary drums, while Dhamsa provides rhythmic support. Ektara is a string instrument and not used as percussion. Tuila and Dhhak are percussion instruments, but Dhamsa specifically serves as the subordinate drum in these ensembles.
