Dhak (instrument)

It is of medieval origin, and is used in Hindu religious festivals of the region, especially of Sakta and Shaiva traditions, including Durga Puja, Kali Puja and Charak Puja.

The drum beats, mostly played by the Bengali Hindu community, along with the arati (invocation dance) forms an integral part of Durga Puja unique to Bengal. The Bengali devotional dance Dhunuchi Nritya is performed with the rhythmic beats of Dhak during Durga Puja and Kali Puja in Bengal. The tea-tribes of Assam play dhak along with nagara.

The Statesman wrote, "Durga Puja does not assume the festive aura without the maddening beats of the dhak, the large drum that people hang around their necks and play with two thin sticks to infuse the frenzied rhythm into listeners. Those enchanting beats are enough to conjure up the sights and smells of Durga Puja."

It is also played in Islamic festivals like Muharram in Bengal.
