Bauls are a group of mystic minstrels from Bengal. The term Baul refers to both a syncretic religious sect and a musical tradition used as a vehicle to express Baul thought. Bauls are a very heterogeneous group, with many different streams to the sect, but their membership mainly consists of Vaishnavite Hindus and Sufi Muslims. Visitors can be often identified by their distinctive clothes and musical instruments, such as the ektara. Though Bauls comprise only a small fraction of the Bengali population, their influence on the culture of Bengal is considerable. In 2005, the Baul tradition was included in the list of “Masterpieces of the Oral and Intangible Heritage of Humanity” by UNESCO.
