I just watched a bit and thought what on earth is dressage all about and what exactly do the riders do. I'm sure there is skill involved but honestly I can't see the point of it, it's hardly a sport ??
Not just a huge amount of skill, but also enormous core strength, fantastic balance, ability to make extremely subtle movements and weight shifts while sitting on an animal that is itself moving powerfully. Serious riders cross-train, e.g. by biking or running, pilates, yoga, strength training, to build up the strength and fitness required to sustain a 10-minute Grand Prix dressage test. The horses likewise have to be very fit and strong, and highly trained and balanced to be able to respond to the rider's subtle instructions.
Basically, modern competitive dressage began as a way of demonstrating the level of training (French: "dressage") of cavalry horses and riders. For a long time, only cavalry officers could compete in the Olympics! All of the movements are natural to the horse, in that horses can be seen doing versions of them in the field. However, to do them with a rider, in a choreographed test, requires a huge amount of training. Ideally, a well-trained horse with a well-trained rider can go in any direction, at any pace/speed, at any moment: a dressage test is used to demonstrate this ability.
Fundamentally, dressage (in whatever style) should be the foundation for everything...not at GP level, of course, but in the sense that the horse and rider are trained to communicate, and the horse learns how to balance and carry a rider in a healthy way.
Dressage displays to music have been around for hundreds of years. The idea of using them for the individual final at the Olympics is newer: I think it was done for audience appeal? While I like watching a good Kür, I'm not that keen on it being the Olympic final. It seems gimmicky.
