Dance is an art form that generally refers to movement of the body, usually rhythmic and to music, used as a form of expression, social interaction 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. Breakdancing and Krumping are related to the hip hop culture. African dance is interpretative. Ballet, Ballroom, Waltz, and Tango are classical styles of dance while Square Dance and the Electric Slide are forms of step dances.
Every dance, no matter what style, has something in common. It not only involves flexibility and body movement, but also physics. If the proper physics are not taken into consideration, injuries may occur.
Choreography is the art of creating dances. The person who creates (i.e., choreographs) a dance is known as the choreographer.
