The dances of the Nagas portray a sense of fun and zest in their life. Harvesting season is main celebration time for all the Naga tribes, which they rejoice through the performance of various dances. Then, there are other occasions on which the dances are performed. The characteristic feature of all Naga dancing is the use of an erect posture, with many movements of the legs and comparatively little use of the torso and shoulders. Also they perform it to celebrate their victory against enemies.
