Dressage
Its fundamental purpose is to develop, through standardized progressive training methods, a horse's natural athletic ability and willingness to perform. The rider will be relaxed and appear effort-free while the horse willingly performs the requested movement.
The dressage training scale is arranged in a pyramid or sequential fashion, with “rhythm and regularity” at the start of the pyramid and “collection” at the end
Rhythm and regularity Rhythm, gait, tempo, and regularity should be the same on straight and bending lines, through lateral work, and through transitions. Rhythm refers to the sequence of the footfalls, which should only include the pure walk, pure trot, and pure canter. The regularity, or purity, of the gait includes the evenness and levelness of the stride. Once a rider can obtain pure gaits, or can avoid irregularity, the combination may be fit to do a more difficult exercise. Even in the very difficult piaffe there is still regularity: the horse "trots on the spot" in place, raising the front and hind legs in rhythm.
Relaxation The second level of the pyramid is relaxation (looseness). Signs of looseness in the horse may be seen by an even stride that is swinging through the back and causing the tail to swing like a pendulum, looseness at the poll, a soft chewing of the bit, and a relaxed blowing through the nose. The horse makes smooth transitions, is easy to position from side to side, and willingly reaches down into the contact as the reins are lengthened.
Contact The third level of the pyramid—is the result of the horse’s pushing power, and should never be achieved by the pulling of the rider’s hands. The rider encourages the horse to stretch into soft hands that allow the horse to lift the base of the neck, coming up into the bridle, and should always follow the natural motion of the animal’s head. The horse should have equal contact in both reins.
Impulsion The pushing power (thrust) of the horse is called impulsion, and is the fourth level of the training pyramid. Impulsion is created by storing the energy of engagement (the forward reaching of the hind legs under the body).Impulsion can occur at the walk, trot and canter. It is highly important to establish good, forward movement and impulsion at the walk, as achieving desirable form in the trot and canter relies heavily on the transition from a good, supple, forward walk. Impulsion not only encourages correct muscle and joint use, but also engages the mind of the horse, focusing it on the rider and, particularly at the walk and trot, allowing for relaxation and dissipation of nervous energy.
Straightness A horse is straight when the hind legs follow the path of the front legs, on both straight lines and on bending lines and the body follows the line of travel. Straightness allows the horse to channel its impulsion directly toward its centre of balance, and allows the rider’s hand aids to have a connection to the hind end.
Collection. Collection requires great muscular strength, so must be advanced upon slowly. When in a collected gait, the stride length should shorten, and the stride should increase in energy and activity. When a horse collects, more weight moves to the hindquarters. Collection is natural for horses and is often seen during pasture play. A collected horse is able to move more freely. The joints of the hind limbs have greater flexion, allowing the horse to lower the hindquarters, bringing the hind legs further under the body, and lighten and lift the forehand. In essence, collection is the horse's ability to move its centre of gravity to the rear.
