The dholak (Punjabi: ਢੋਲਕ, Bengali: ঢোলক, Hindi: ढोलक; Nepali: ढोलक; Dutch: dhool in the Netherlands and Suriname and Sinhalese: ඩොල්කි) is a South Asian two-headed hand-drum. 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.
