Bayan: tap for Ga. Rest the heel low, tap for Ge; press it up for Gi. Slide the heel up and the pitch rises. Ke at the far edge. Dayan: Te on the syahi. Rest a finger on its edge: Na on the rim, Ta inside. Lift it: Tu.
Hard: a heel or a resting finger strikes less. The heel's place grows; so does the ring round the syahi.
Keys: Z Ke, X Ge, C Ga, V Gi · M Te, comma Te, J Ta, K Tu, L Na. Tarang: 1 to 9.
One plays the bayan, one the dayan, peer to peer. Each sounds its own drum.
