In the past, when horses were used in war, canter pirouettes were simply handy when riding fast. To be able to turn around on-site in both directions if the enemy came towards you. If you weren’t able to, you might get killed. It was also a good thing to be able to stand at a distance and move on-site, so it looked as if you were coming towards the enemy. That was how piaffe was invented. You had to be able to go backwards and sidewards. Ride with one hand. People spent hundreds of years fine-tuning that. The kind of dressage that we know today is called modern riding. Out of the 5,000 years that the horse has been domesticated, it is perhaps something that we have worked with in about 20 minutes. So, when you look at the big picture, modern dressage only takes up a little space.
