Formation ballroom dance involves anywhere from two to dozens of couples performing a choreographed ballroom dance routine. These routines generally feature at least some free-form choreography, which may include movements from jazz dance, ballet, or any other type of dance.
The choreography of a 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.
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.
This is normally danced to tunes in common time (32 bar and the dance is 64 bars long) but can be and is sometimes done to jigs (6/8 tempo).
Both lines dance forwards, one line raising their hands in an arch and the other line dancing underneath, and dance on to meet the next set of three coming in the other direction.
Formation: four couples arranged around a square, lady on the right of the man. Couple with their backs to the music are couple number 1, couple on their left number 2, couple opposite number 3 and couple on the right number 4 (ie numbering clockwise).
