What are quadrilles, pas de deux, and pas de trois?
Quadrilles, pas de deux, and pas de trois are the only classes in competitive dressage where more than one horse is in the arena at a time. Pas de deux teams consist of two horses and two riders, pas de trois teams consist of three horses and three riders, and quadrille teams consist of four horses and four riders. In each, semblance as a team, performance as a team & individually, and the quality of the movements are stressed and scored. In quadrilles, unlike pas de deux and pas de trois, teams perform U.S.D.F.-sanctioned tests. Pas de deux and pas de trois teams invent their own tests.
