Udakkiya
This instrument is about 1 feet in length and is shaped like a sand clock. Udakkiya is made by carving either the Suriya or Ahala timber
in to two apetures. These apertures are then bound tightly with the leather of the monkey or the Iguanna and both the sides are connected with tightly streched twine.

Udakkiya is played with 2 sticks called 'Walayan'. The pitch of the sound can be changed by applying pressure on the twine with a bound cloth.
