Tansen Sangeet Mahavidhyalay in Kalkaji means business, and they have some intensive music courses – but they also have activity classes if you’re looking to take up singing as a hobby or want to brush up on your skills. They organise fun summer camps for music classes and have an excellent faculty. They also host plenty of music and dance festivals you get to participate in. They’re pretty flexible with classes and timings.
