The dhak (Bengali: ঢাক) is a huge membranophone instrument from South Asia. The shapes differ from the almost cylindrical to the barrel. The manner of stretching the hide over the mouths and lacing also varies. It suspended from the neck, tied to the waist and kept on the lap or the ground, and usually played with wooden sticks. The left side is coated to give it a heavier sound. Drum beats are an integral part of Durga Puja.
