The tabla is a set of twin drums. While occasionally played solo, it is an indispensible accompaniment for all types of music in Pakistan.
The drum played by the right hand is the main drum, called the the dayan, while the one played by the left hand is known as thebayan or dugga/duggi. Both drums are covered with goat skin. In the centre is a black circle, the siyahi, about 5 centimeters in diameter, which is made by pasting iron slag powder on the skin surface. Its purpose is to tune the drum to the correct pitch.
