Dance

Dance is the art of precise, expressive, and graceful human movement, traditionally, but not necessarily, performed in accord with musical accompaniment. Dancing developed as a natural expression of united feeling and action.

Dance is a performance art form consisting of purposefully selected sequences of human movement. This movement has aesthetic and symbolic value, and is acknowledged as dance by performers. 

Dance is generally, though not exclusively, performed with the accompaniment of music and may or may not be performed in time to music.

"Dance is human movement created and expressed for an aesthetic purpose."
