Bhaona forms the traditional art of popular theatre performed in Assam. It usually has religious content based on the scriptures of Mahapurusha Srimanta Sankardeya. When presented in the form of a play it is called Ankiya Nat and their staging is called Bhaona. These are usually performed at the satras in village and urban setting in Assam. Masks, costumes and jewellery form an important part of presenting the different characters of the play.

During a Bhaona play, the Sutradhari is the person who recites the shlokas, sings and dances and explains in prose at the different stages and messages of the Bhaona. The Gayan are the singers and Bayan are the percussionist and the instrumentalist who perform during the Bhaona.
