The history of dance is difficult to access because dance does not often leave behind clearly identifiable physical artifacts that last over millennia, such as stone tools, hunting implements or cave paintings. It is difficult to determine the exact point at which dance became part of human culture. Dance is filled with aesthetic values, making it distinct from one society to another. It is filled with symbolism that expounds on the cultural heritage of a community, each style being unique from one another. Dance can help tell a story, convey feelings and emotions, and connect with others and ourselves.
