English: The idakka (Malayalam: ഇടയ്ക്ക), also spelt edaykka, is an hourglass-shaped drum from Kerala in south India. This handy percussion instrument is very similar to the pan-Indian damaru. While the damaru is played by rattling knotted cords against the resonators, the idakka is played with a stick. Like the damaru, the idakka's pitch may be bent by squeezing the lacing in the middle.
