Dance (from French danser, perhaps from Frankish) generally refers to movement used as a form of expression, social interaction or presented in a spiritual or performance setting.Dance is also used to describe methods of non-verbal communication between humans or animals, motion in inanimate objects , and certain musical forms or genres. ********************************* Dance can be directly 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/symbolic system as in many Asian dances. Dance can embody or express ideas, emotions or tell a story. Definitions of what constitutes dance are dependent on social, cultural, aesthetic, artistic and moral constraints and range from functional movement to virtuoso techniques such as ballet. In sports, gymnastics, figure skating and synchronized swimming are dance disciplines while Martial arts 'kata' are often compared to dances.
