In dressage, a trot half-pass is the same thing as a half-pass in the canter, only the trot has a two-beat rhythm, and the horse needs to take its shoulders and haunches over in the same direction that it's looking. Alternate half-pass rights with half-pass lefts with helpful advice in this video on horse training and dressage.
Okay. So now we're going to show the trot half-pass. We did a little bit in the canter half-pass. Now, we're going to ride it in the trot. Same thing. The trot is a two-beat rhythm, and the horse has to be bending around your inside leg, taking the shoulders and haunches over in the same direction that he's looking. Very difficult. It's not natural for a horse to do that. My half-pass right first. Set him up, bending him. Half-pass right. And then I'll set him up for a half-pass left. Inside leg, bending, taking the shoulders. Good. And then you can alternate as well, going half-pass right to half-pass left. Changing it over, half-pass left. So this can definitely be performed in the trot or canter, and is in the tests -- not in the walk, though, just in the trot and in the canter.
