  ASSAM 
  It is made out of a piece of thin flat bamboo about 1.5-2 cm wide and 20-25 centimetre long. The centre is cut away so as to leave a prong attached to the frame at one end. This prong vibrates when stuck by the thumb. Sometimes a string is fastened to this and by jerking this string the prong is made to vibrate. Generally it is played by women with other instruments in bihu dance.
