Even though many may not understand the language in this video, the computer generated images speak for themselves. Of special note is the relationship of riding the horse’s head and how that affects the rest of the horse’s body and movement. There’s a really good example of a correct trot and an incorrect trot. Be sure to watch, not just the changed posture of the horse, but also the changed movement, ie. the swing of the limbs, the placement of the feet. Also note the difference of pulling the horse’s chin into its chest, versus pulling the horse’s head up and then the chin in, and then finally encouraging the horse to stretch forward and down with its neck and head, and opening its throat.
