Udukkai is an hourglass-shaped instrument used for devotional and folk music in India. If we tighten the lace in the middle it changes the pitch. It is made of wood or brass. It is very good in the market as the features are unmatchable.
The udukku is covered with skin surfaces covered on both sides. Timila’s smaller version is Udukku. The fingers of one hand are used for playing and another hand is used for adjusting the sound with strings support at the middle. It’s used for adjusting sruti and melam.
Edakka is also shaped like an hourglass. The instrument is 8 to 10 inches with a girth of 6 to 8 inches on both ends that taper towards the centre. The udukku’s body is made from jackfruit wood. Brass body is used in some parts. The mouth of the instrument is closed with dried and cured animal goatskin. The edges of the instrument body and the skin are made very tight by using the strings. One side can be played by one or two metallic wires which enable the player to generate resonance. With a strap of cloth, it’s fixed at the middle for clasping. To embellish the instrument some coloured cotton balls are hung freely.
