Dance is an art form consisting of sequences of body movements with aesthetic and often symbolic value, either improvised or purposefully selected. Dance can be categorized and described by its choreography, by its repertoire of movements, done simultaneously with music or with instruments; or by its historical period or place of origin.

An important distinction is to be drawn between the contexts of theatrical and participatory dance, although these two categories are not always completely separate; both may have special functions, whether social, ceremonial, competitive, erotic, martial, sacred or liturgical. Other forms of human movement are sometimes said to have a dance-like quality, including martial arts, gymnastics, cheerleading, figure skating, synchronized swimming, marching bands, and many other forms of athletics. Dance is not solely restricted to performance, though, as dance is used as a form of exercise and occasionally training for other sports and activities. Dance itself has also become a sport for some, with dancing competitions found across the world exhibiting various different styles and standards.

Dance requires an equal amount of cognitive focus as well as physical strength. The demanding yet evolving art form allows individuals to express themselves creatively through movement, while enabling them to adapt movement that possesses a rhythmical pattern and fluid motions that allure an audience either onstage or on film. Dance is considered to be a very aesthetically pleasing art form.
