The autumnal dance of the Baiga tribe of Madhya Pradesh, mostly living in and around Mandla district, is called Bilma which literally means the union of two groups. A group of Baigas living in one place is called Chak. Dancers of one Chak go to another Chak. Dancers of both the Chaks perform Bilma together. The accompanying melodic music is provided by Bansuri (flute), and the drum music by Mandar, Dholak and Timki.
