Among all the dances the best and the most attractive dance in Assam is the Bagurumba dance. This is mainly a formation dance performed with slow steps and outstretched hands. A group of girls dressed in most colourful dokhna, jwmgra and aronai costumes usually perform this dance with the accompaniment of traditional musical instruments of Bodos. This dance is common in the Bodo inhabited areas of Kokrajhar, Bongaigaon, Nalbari, Darrang and Sonitpur districts. This dance is also called as the Bardwisikhla dance.
The dance is the usually performed during Bwishagu festival of the Bodos in the Bishuba Sankranti or in Mid-April. The Bwishagu festival begins with a worship of the cows and then the young people bow down to their parents and other elders in the house. After this the Bathou is worshipped by offering the deity chicken and zou i.e rice beer. The musical instruments like Serja, Sifung and Tharkha also accompany the dance. With these instruments, Kham, a long drum made of wood and goatskin and Gongona, a musical instrument of a curved horn is also used. The festival is celebrated with pleasure in all areas of Bodo community. This festival ends with a community prayer at Garjasali.
