Ballroom dance, Music of Ballroom dance.

The choreography of a ballroom dance formation team includes both choreography of a ballroom routine of an individual couple and the overall pattern of movements of the couples on the stage. The routines generally feature at least some free-form choreography, which may include movements from jazz dance, ballet, or any other type of dance.

Formation routines allow dancers to show off their own technique in addition to their ability to move as a team.

Formation routines may be based on a particular dance, e.g., Tango routine or Cha-cha-cha routine. Another popular format is a potpourri routine, often a mixture of dances of the same category, e.g., of International Latin formation or International Standard formation. The latter format is used during the competitions of ballroom formation teams.

Ballroom dance, refers collectively to a set of partner dances, which originated in the Western world and are now enjoyed both socially and competitively around the globe. Its performance and entertainment aspects are also widely enjoyed on stage, in film, and on television.

While historically ballroom dance may refer to any form of formal social dancing as recreation, with the eminence of dancesport in modern times the term has became much narrower in scope, usually referring specifically to the International Standard and International Latin style dances (see dance groupings below). In the United States, two additional variations—"American Smooth" and "American Rhythm"—have also been popularized and are commonly recognized as styles of "ballroom dance".
