These are, ...a high degree of collection (i.e. (1) ....suppleness of haunches and (2) ...shortening of the body...), (3) ...highly elevated neck, (4) ...withers raised, (5) ...diligent, almost exalted, rhythmic steps, (6) ...little ground gained, and most importantly, (7) ...self-propulsion (...Schwung...)...
(14)...b. ...the school trot, like the school walk, develops from proper collection (i.e. supple haunches and a shortening of the body...) in horizontal balance (...Richtung ins Gleichgewicht, i.e. without the elevation of neck and withers...)...
