Dance is a type of art that generally involves movement of the body, usually rhythmic and to music, performed in many different cultures and used as a form of expression, social interaction and exercise or presented in a spiritual or performance setting.
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 that incorporate dance, while martial arts kata are often compared to dances. Motion in ordinarily inanimate objects may also be described as dances (the leaves danced in the wind).
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.
Dancing has evolved many styles. African dance is interpretative. Ballet, ballroom (such as the waltz), and tango are classical styles of dance while square dancing and the electric slide are forms of step dances. More recently evolved are breakdancing and other forms of street dance, often associated with hip hop culture.
