Old Indian Bangla songs are Eastern classical pieces originating from the Indian state of West Bengal and the country of Bangladesh. Religious and secular songwriting styles both exist.
Bangla music was initially influenced by Sanskriti chants as well as Vaishnav poetry. The music started off being purely devotional, but secular songwriters soon emerged. One style of Bangla music is called Bishnupur Gharana. This style originated in Bishnupur, Bankura, and was created by court musicians serving Malla Kings.
Another classical style of Bangla is called Baul. This literally translates to "divinely inspired insanity" and was the name of minstrels from the old Bengal region who sang mainly during the 1600s and 1700s. Their inspirations were the Hindu Kartabhajas and Muslim Sufi philosophers.
One of the most defining forms of Bengali music is the Rabindra Sangeet. This form was created by songwriter and poet Rabindranath Tagore. These songs deal with themes of love, nature and patriotism. Tagore was initially inspired by Krishna and later by the concept of transcendentalism. Tagore's style of music is said to have influenced later artists, including Shantideb Ghosh, Debabrata Biswas and Subinoy Roy.
Old Bangla music has slowly evolved and diverged due to the influence of Western media. Newer Bengali music is performed by traditional classical singers as well as pop singers, rock singers and hip-hop singers.
