The Dholki is a South Asian two-headed hand-drum. It is also known as Nal. It screw-turnbuckle tensioning on both sides. This is longer than Dholak and having lesser diameter. The Dholki 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. This is the instrument used for high pitch music.
