Which dressage movement involves the horse moving sideways and forwards while on two tracks?

The half pass is a specific dressage movement characterized by the horse moving both sideways and forwards simultaneously while maintaining engagement and balance. In a half pass, the horse travels diagonally across the arena on two tracks, which means that the horse's two front legs move in a separate line from the two hind legs. This movement demonstrates the horse's ability to bend around the rider's leg while maintaining forward momentum, showcasing its suppleness and responsiveness.

This movement requires the horse to maintain a proper rhythm, balance, and alignment, reflecting the refinement of training in dressage. The half pass is often executed at various gaits, including trot and canter, and is integral in demonstrating advanced levels of training and communication between horse and rider. It is also a fundamental transition that prepares the horse for even more complex movements within dressage.
