The airs above the ground or school jumps are a series of higher-level, Haute ecole, classical dressage movements in which the horse leaves the ground. They include the capriole, the courbette, the mezair, the croupade and the levade. None are typically seen in modern competitive dressage. They are performed by horses of various riding academies such as the Spanish Riding School in Vienna and the Cadre Noir in Saumur, and may be seen in other dressage performances. The levade and courbette are a particular feature of the Doma Menorquina, the riding tradition of the island of Menorca. Horses such as the Andalusian, Lusitano, Lipizzan and Menorquín are the breeds most often trained to perform the airs today, in part due to their powerfully conformed hindquarters, which allow them the strength to perform these difficult movements. There were originally seven airs, many of which were used to build into the movements performed today.
