DANCE

Dance is an art form often classified as a sport, 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 or by its historical period or place of origin.^[3] Dance is typically performed with musical accompaniment, and sometimes with the dancer simultaneously using a musical instrument themselves.

An important distinction is to be drawn between theatrical and participatory dance,^[4] 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, as dance is used as a form of exercise and occasionally training for other sports and activities. Dance has become a sport for some, with dancing competitions found across the world exhibiting various different styles and standards. Dance has an aesthetic appeal to many people.^[

Dance is generally, but 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 or gumboot 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. The choreography and music are meant to complement each other, to express a story told by the choreographer and dancers.^[16]

Dances generally have a characteristic tempo and rhythmic pattern. The tango, for example, is usually danced in ²
₄ time at approximately 66 beats per minute. The basic slow step, called a “slow”, lasts for one beat, so that a full “right–left” step is equal to one ²
₄ measure. The basic forward and backward walk of the dance is so counted – “slow-slow” – while many additional figures are counted “slow – quick-quick”.^[18]

Repetitive body movements often depend on alternating “strong” and “weak” muscular movements.^[19] Given this alternation of left-right, of forward-backward and rise-fall, along with the bilateral symmetry of the human body, many dances and much music are in duple and quadruple meter. Since some such movements require more time in one phase than the other – such as the longer time required to lift a hammer than to strike – some dance rhythms fall into triple metre.^[20] Occasionally, as in the folk dances of the Balkans, dance traditions depend heavily on more complex rhythms. Further, complex dances composed of a fixed sequence of steps always require phrases and melodies of a certain fixed length to accompany that sequence.
