The two ends are covered with single pieces of hide cap, these are joined across the drum with a single piece of thin rope. Small metal rings are placed in between the ropes are for tuning purposes. A mixture containing tamarind is placed inside the centre of the left cap which enhances the bass sound. The instrument is played with both hands in a peculiar fashion. It is popular folk instrument and is widely used by the qawali musicians of Pakistan. In recent times the dholak has been in introduced in South Indian classical music. The sound is a balance between treble and bass. Varied rhythmic patterns are created on the dholak sending listeners into ecstasy.
