Description: The idakka [in Malayalam: ഇടയ്ക്ക or alternatively spelt as edaykka / edakka] is a small sized hourglass drum from Kerala, South India. Similar in resemblance and construction to the damaru.
Playing Techniques: Playing the idakka does differ then, the playing of the damaru. The damaru is struck by knotted cords against the membranes. Also the idakka is played with a stick. Similarly the the idakka’s pitch may be bent by squeezing the lacing in the middle. The idakka is slung over the left shoulder and the right side of the instrument is gently beaten with a thin curve-ended stick.
Construction: Similar in appearance to other hourglass drums of this size. The Idakka consists of two circular drum heads that are mounted to each other within a circular ring. The hourglass-shaped body is placed between the two heads and lacing is used to pull the two rings towards each other, stretching each drum head over an open end of the body.
Snare-like strings made of natural fibre are stretched across the open ends of the drum body, under each drum head. It is not uncommon for the diameter of the drum heads to be larger than the diameter of the body, with the result that the drum heads are often seen mounted significantly off-center.
