Sangrai dance is performed by the Mog community people on the occasion of Sangrai festival falling in the month of Chaitra of Bengali calendar year. Young boys and girls in particular, celebrate the day through cultural programmes to invite the New Year.
This popular form of dance is characteristic of the Chakma community. Bijhu means ‘Chaitra-Sankranti’. ‘Chaitra-Sankranti’ denotes end of Bengali calendar year. It is during this period when the Chakmas sing and dance to bid good-bye to the year just being ended and welcome the New Year. The dance is beautifully orchestrated with the rhythm playing of what is known as ‘Kheng-garang’, ‘Dhukuk’ and flute. Chakma women wear flowers on hair and metal ornaments.
While the theme of the dance remains almost to be the same as of other tribes, the dance form of the Reang community is quite different from others. The movement of hands or even the upper part of the body is somewhat restricted, whereas the movement beginning from their waist down to their feet creates a wonderful wave. Standing on an earthen pitcher with a bottle on the head and a lighted lamp on it, when the Reang belle dance twisting rhythmically the lower part of the body, the dance bewilders the onlookers. The Reangs also use the musical Instruments like Khamb, Flute made of bamboo and bamboo cymbal. The Reang women prefer to put on black Pachra and Rea. Reang women put on coins ring, which generally covers their entire upper region. They also put on rings made of coin in their ears. They are fond of fragrant flowers as ornaments to metal things.
The life and culture of Tripuris revolve around Jhum (shifting) cultivation. When the sowing of seeds at a plot of land selected for Jhum is over by middle of April, they pray to the God ‘Garia’ for a happy harvest. The celebrations attached to the Garia Puja continue for seven days when they seek to entertain their beloved deity with song and dance.
