What body language is involved in a flying change?

The body language of a flying change is one of the most refined and most misunderstood aspects of the movement. The most correct and most elegant flying changes are produced by a rider whose body language communicates the change so clearly and completely that the leg and rein aids become secondary refinements rather than the primary triggers. A horse educated to read the rider's body will feel a flying change coming before the leg is ever applied, because the weight shift, the seat reorganization, and the subtle postural changes that precede the leg cue have already told him what is being asked. The weight shift is the most fundamental piece of body language in the flying change. Before the new leg aid is applied, the rider's weight needs to transfer from the current inside seat bone to the future inside seat bone — from right to left for a change from right lead to left lead. This weight shift loads the new inside hind leg at the moment when the horse needs to push off and initiate the new lead. The timing must arrive at the moment of the suspension — the fraction of a second when all four feet are off the ground — because the suspension is the only moment when the horse can reorganize his footfall sequence. The new outside leg is the specific trigger aid that tells the horse which lead is being requested, arriving at the horse's side slightly behind the girth at the moment of the suspension simultaneous with or fractionally after the weight shift. The old outside leg releases its position as the new outside leg applies — a simultaneous swap of leg position that mirrors the change in lead. Many riders fail to release the old outside leg when applying the new one, creating confusion rather than clarity. The hands play a supporting and confirming role rather than an initiating one. The inside rein of the new lead should open very slightly in the direction of the change — a subtle opening rein that invites the horse's forehand to step in the direction of the new lead without pulling or restricting. Eyes and focus complete the body language picture — where a rider looks at the moment of the flying change directs the weight, the shoulders, and ultimately the horse in a way that is surprisingly powerful. A rider who looks through the change in the new direction naturally organizes her body in the direction she is looking.
