The udukai(Tamil: உடுக்கை) or uduku is a membranophone instrument used in folk music and prayers in Tamil Nadu and it is originated as well. Its shape is similar to other Indian hourglass drums, having a small snare stretched over one side. The udaku is played with the hand and the pitch may be altered by squeezing the lacing in the middle. The damru in the hands of Lord Shiva is also referred to as udukai.
