The earliest music in Bengal was influenced by Sanskrit chants, and evolved under the influence of Vaishnav poetry such as the 13th-century Gitagovindam by Jayadeva, whose work continues to be sung in many eastern Hindu temples. The Middle Ages saw a mixture of Hindu and Islamic trends when the musical tradition was formalized under the patronage of Nawabs and the powerful landlords baro bhuiyans.
Much of the early canon is devotional, as in the Hindu devotional songs of Ramprasad Sen a bhakta who captures the Bengali ethos in his poetic, rustic, and ecstatic vision of the Hindu goddess of time and destruction in her motherly incarnation, Ma Kali. Another writer of the time was Vidyapati. Notable in this devotional poetry is an earthiness that does not distinguish between love in its carnal and devotional forms; some see connections between this and Tantra, which originated some time in the middle of the first millennium CE.
