Training our horses for us to have a comfortable ride is a main aim of dressage. We should train in a way that retains or enhances the natural way the horse goes, and that he is happy under the control of his rider.
At the beginning of his training we require that we have balance, rhythm and suppleness and the quality takes priority of accuracy. We also take into account the ability of the horse we are training and the character he shows.
As training evolves, we increase the engagement that will change the frame and outline from the horizontal novice towards the collected advanced horse.
As we progress we expect obedience and submission but still with a happy attitude.
