Dance can be participatory, social or performed for an audience. It can also be ceremonial, competitive or erotic. Dance movements may be without significance in themselves, such as in ballet or European folk dance, or have a gestural vocabulary or symbolic system as in many Asian dances. Dance can embody or express ideas, emotions or tell a story.
