The vocal paste , in India syahi, siyahi or was is one, particularly in the South Asian drum traditions occurring method, the vibration behavior to change the coat. On the one hand, the purpose of the voice paste can be to increase the mass of the vibrating head, thereby making the head sound deeper than its diameter would correspond to. On the other hand, the tuning paste can be used to dampen undesired overtones so that tones with a low level of noise can be generated through a targeted attack.
In the simplest cases, a lump of a rice - lime mixture is glued to the fur before playing. In the case of highly developed instruments such as the tabla, on the other hand, a secret mixture is rubbed into the skin during drum manufacture, so that a permanent, black stain is created.
With the dholak , the voice paste is a moist pudding-like mass that is attached to the inside of the bass head. In the pakhawaj , the bass skin's voice paste is prepared from water and wheat flour like a kind of bread dough before each game and stuck onto the skin as a flat “pancake”; Some modern instruments use a permanent silicone voice paste .
