Here is an interesting video from this style of dancing that originated in Bengal - the dance school is run by the sister of Dr. Mahua Mukhopadhaya who has revived the dance form (much like how Smt. Swapna Sundari has revived AndhrA naTyam). Dr. Mukhopadyaya was petitioning the SNA to get gauDiya nRtya classified as one of the 'Classical' dance forms of India.
I would appreciate answers to the following questions:
How is a dance declared as 'classical'?
What are the currently listed classical dance forms in India?
