For the Tlingit people dance was a way of showing emotion, whether it would be a story, an apology or for shamans talking to spirits. Dancing is the most important part of a potlach because dancing is like a universal language, everybody knows what it is. Although some of us try to dance were not too good at it and thats why we keep the dancing to the dancers. In this case the dancers are the Tlingits.
