Dance is the intentional investigation of the movement of the body, through space and time. As long as the function of the investigation is explicitly held in movement exploration, it is dance. Dance has held an important function in society throughout all of history. Dance has functioned as a way of understanding ourselves as a community; what we ritualize, how we celebrate, what we believe, how we relate to one another, how we understand the role of the human community in relationship to the web of life. Through folk dancing, sacred dancing, and concert dancing, the identity of a human community can be deconstructed through analysis of its dance.
