The Tas [tAs] is another percussion instrument of Kurdistan's Dervishes played alongside the daf at the climax of the Sama.
The Tas is constructed from a metallic bowl and covered with skin, stretched tight by belts on the sides of the bowl. The Tas is placed on the ground and played by two wide leather straps.
This instrument is also played during eclipses and ritual ceremonies for rain on the rooftops in Kurdistan.
