The dholak is a two-headed hand-drum from the Indian subcontinent. It may have traditional cotton rope lacing, screw-turnbuckle tensioning or both combined: in the first case steel rings are used for tuning or pegs are twisted inside the laces.
The dholak is mainly a folk instrument, lacking the exact tuning and playing techniques of the tabla or the pakhawaj. The drum is pitched, depending on size, with an interval of perhaps a perfect fourth or perfect fifth between the two heads.
It is related to the larger dhol and the smaller dholki.
