Known from xiii th century, this is a drum barrel converted hourglass by adding membranes wide overhanging ends.

These drums are characterized by a modifiable tension of the pitch of the sound during the play and thus have a melodic vocation as much as rhythmic.

The cow or goat skin membranes are glued to a thick (2 cm) ring (22 cm in diameter) in vegetable fiber pierced with six holes through which a cotton tension cord passes, also allowing the membrane to be held in place by lacing in W. Bells are attached to the lacing.

It receives various names: hurki (Uttar Pradesh), dâk or deru (Rajasthan), daklû (Gujarat) and guruki (Maharashtra).

It is again the left hand which holds the instrument by grasping it at the central part while varying the tension and therefore the pitch of the sound, while the right strikes the only playing side.

They also receive other names: studied, idaisurangu decked and davandai (larger and thicker, played to the stick).

They also have a metal or plant or animal fiber stamp under the left membrane ensuring a specific buzz .
