Dance is a powerful impulse, but the art of dance is that impulse channeled by skillful performers into something that becomes intensely expressive and that may delight spectators who feel no wish to dance themselves. These two concepts of the art of dance—dance as a powerful impulse and dance as a skillfully choreographed art practiced largely by a professional few—are the two most important connecting ideas running through any consideration of the subject. In dance, the connection between the two concepts is stronger than in some other arts, and neither can exist without the other.
Although the above broad definition covers all forms of the art, philosophers and critics throughout history have suggested different definitions of dance that have amounted to little more than descriptions of the kind of dance with which each writer was most familiar. Thus, Aristotle’s statement in the Poetics that dance is rhythmic movement whose purpose is “to represent men’s characters as well as what they do and suffer” refers to the central role that dance played in classical Greek theatre, where the chorus through its movements reenacted the themes of the drama during lyric interludes.
Dance is generally, though not exclusively, performed with the accompaniment of music and may or may not be performed in time to such music. Some dance (such as tap dance) may provide its own audible accompaniment in place of (or in addition to) music. Many early forms of music and dance were created for each other and are frequently performed together. Notable examples of traditional dance/music couplings include the jig, waltz, tango, disco, and salsa. Some musical genres have a parallel dance form such as baroque music and baroque dance; other varieties of dance and music may share nomenclature but developed separately, such as classical music and classical ballet.
