Gombhira
Gombhira (or gambhira or gamvira) is a type of song originating in the Bengal region in the eastern part of the Indian subcontinent, what is today northeastern West Bengal, India and northwestern Bangladesh.
In West Bengal (India), gombhira performances are centred around the Malda District whereas Chapai Nawabganj District is the main centre of Gambhira performances in Bangladesh. The tradition is also popular in the nearby districts of Rajshahi and Naogaon. It is performed with a particularly distinctive rhythm and dance with two performers, always personifying a man and his maternal grandfather, discussing a topic to raise social awareness.
