The capriole is one of the "airs above the ground" in classical dressage. It is not seen in modern competitive dressage, but is performed by the horses of the Spanish Riding School in Vienna and the Cadre Noir in Saumur.
In the capriole, the horse jumps from a raised position of the forehand straight up into the air, kicks out with the hind legs, and lands more or less on all four legs at the same time. It requires an enormously powerful horse to perform correctly.
