The dholak is basically a double headed drum with the bass head on one side and the treble head on the other. The left hand is also a single membrane with a special application on the inner surface. This application is a mixture of tar, clay and sand (dholak masala) which lowers the pitch and provides a well defined tone. On the treble drum side, there is no putty added.
