Music is an integral part of Bengali culture. Almost every Bengali girl in Kolkata learns singing. The older generations (and all the Non-Bengali persons I have come across and who were familiar about Bengali culture) actually expect every Bong girl to know how to sing “Robindro Songeet” but all of us DON’T know!! And then we are looked down upon for being “Probashi” (Out of state residents) and for being contrary to Bengali culture. Anyway that is another long story. Let me quote Wikipedia to explain what is Robindra Songeet.
Rabindra Sangeet also known as Tagore Songs in English, is a form of music composed by Rabindranath Tagore who added a new dimension to the musical concept of India in general and Bengal in specific. The Rabindrasangeet, which deal with varied themes are immensely popular and form a foundation for the Bengali ethos that is comparable to, perhaps even greater than, that which Shakespeare has on the English-speaking world. It is said that his songs are the outcome of 500 years of literary & cultural churning that the Bengali community has gone through.
