Dholak

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.
