Quadrille
Is most simply defined as team riding. Competitive teams of four riders perform both compulsory and musical freestyle routines. It is an activity suitable to persons of all ages.

In a quadrille competition the main criteria is the team's performance as a cohesive group. Compulsory routines test the team's ability to perform required movements according to acceptable standards. In the exciting Freestyle, the routines are more complex, creating a "kaleidoscope effect" as horses interweave choreography and music in original patterns.

In each performance, judges look for the teams to keep even spacing (from horse to horse), move and turn in synchrony and maintain alignment throughout the ride.

In the freestyle competition, the team's artistic skill is showcased in the interpretation of the music and the creativity of their choreography.
