Ballroom dance is a set of partner dances, which are enjoyed both socially and competitively around the world. Because of its performance and entertainment aspects, ballroom dance is also widely enjoyed on stage, film, and television.
Ballroom dance may refer, at its widest definition, to almost any type of partner dancing as recreation. However, with the emergence of dancesport in modern times, the term has become narrower in scope, and traditionally refers to the five International Standard and five International Latin style dances (see dance categories below). The two styles, while differing in technique, rhythm and costumes, exemplify core elements of ballroom dancing such as control and cohesiveness. Developed in England, the two styles are now regulated by the World Dance Council (WDC) and the World DanceSport Federation (WDSF). In the United States, two additional variations are popular: American Smooth and American Rhythm, which combine elements of the Standard and Latin styles with influences from other dance traditions.
There are also a number of historical dances, and local or national dances, which may be danced in ballrooms or salons. Sequence dancing, in pairs or other formations, is still a popular style of ballroom dance.
The term 'ballroom dancing' is derived from the word ball which in turn originates from the Latin word ballare which means 'to dance' (a ball-room being a large room specially designed for such dances). In times past, ballroom dancing was social dancing for the privileged, leaving folk dancing for the lower classes. These boundaries have become blurred. The definition of ballroom dance also depends on the era: balls have featured popular dances of the day such as the Minuet, Quadrille, Polonaise, Polka, Mazurka, and others, which are now considered to be historical dances.
