What is the gait known as a slow, three beat movement of the horse?

The gait characterized as a slow, three-beat movement of the horse is known as the canter. This gait features distinct footfalls that occur over three beats: the sequence generally involves one hind leg followed by the opposite hind leg and the diagonal front leg together, and then the final front leg. The canter is often used in riding disciplines and shows a smooth rhythm that is both comfortable for the rider and efficient for the horse.

In contrast, the other gaits listed have different characteristics: the trot is a two-beat gait with a diagonal movement pattern, the walk is a four-beat gait that has a distinct four-foot sequence, and the gallop is a fast, four-beat gait. Each of these gaits serves different purposes and has unique rhythms, making it important to distinguish between them based on their individual characteristics.
