Cheraw is a very old colourful, traditional dance of the Mizos. Cheraw is usually performed on the occasion of 'Buhza Aih' (bumper harvest by an individual family). Bamboos are used in this dance. The dancers move by stepping alternatively in and out from between and across a pair of horizontal bamboos, held against the ground by people sitting face to face at either side. They tap the bamboos open and close in rhythmic beats. Two bases, one at each end, support the bamboos, placed horizontally. The bamboos, when clapped, produce a sound, which forms the rhythm of the dance.
