Today's Geo Quiz takes us to the fourth largest city in India.

7-and-half-million Indians live and work in this seaport on the Coromandel Coast. The city is also the capital of the Indian state of Tamil Nadu.

The traditional Music and Dance Season is now underway here. Hundreds of public performances are attracting crowds at concert halls and Hindu temples around the city.

Most performances feature Carnatic music. That's a classical style of South Indian music. You might know this city by its former, Portuguese name.

Or you might know it by the name it took in 1996.

Either way, we'll have the answer...and some music...right here
