The Tabla, a percussion instrument widely used in the performance of North Indian classical music, includes the application of two drums. It is played with both the hands. The drum played with the right hand is made from a hollowed-out block of wood and is generally known as Dayan or Tabla. The Bayan or Dugga is the drum played using the left hand and constitutes either a copper or clay body. Each of these drums is covered with a goat skin and leather braces called baddi. The tone and quality of the sound is controlled by the black circles known as sihai found on top of the skin. Sihai is made of iron powder, water, and a secret element. When played, both the drums produce a variety of tones and pitches.
