Damaru The Hindu religious musical drum “DAMARU” has very strong cultural associations. It is strongly associated with the God Shiva and his followers “SADHUS”. The DAMARU appears to be the last common representative of a family of hour-glass drums. It has a wooden resonator of 4 inches in length and 7 inches in diameter. There are two drumheads on each side of the resonator which are laced together with cord near the centre of the lacing are two loose knotted cords. The knots on each end strike both heads to produce a rattling sound.
