Dance may also be regarded as a form of nonverbal communication between humans, and is also performed by other animals (bee dance, patterns of behaviour such as a mating dance). Gymnastics, figure skating and synchronized swimming are sports dance disciplines, while martial arts kata are often compared to dances. Motion in inanimate objects may also be described as dances (the leaves danced in the wind), and certain musical forms or genres.

Definitions of what constitutes dance are dependent on social, cultural, aesthetic, artistic and moral constraints and range from functional movement (such as folk dance) to virtuoso techniques such as ballet. 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/symbolic system as in many Asian dances. Dance can embody or express ideas, emotions or tell a story.
