Tambour dance, or Chesang Sogochum, is a dance performed while wearing a chesangmo (a hat with a long white ribbon) and playing the sogo (a small drum). The ribbon is supposed to draw circles in the air throughout the whole dance. It requires great levels of concentration and a sense of rhythm to maintain the flow and shape of the ribbon. Jumping and swaying side to side, the dancers have to make sure not to step on the ribbon. The ribbon and the body become one while dancing; it is one of the most elaborate traditional dances of Korea.
