I would mention and teach this part at certain times in the learning of the form but for some reason students tend not to do it. Why?
If they don’t do it then they will miss out on learning a nice technique which uses conservation of angular momentum.
But then why should I be surprised? This part of the movement does not really look important; it looks just like an unimportant transition within a major movement. Nothing that seems worthy of more than a second’s worth of attention during learning and certainly not to bother with during practice.
Maybe its my fault for not showing how to use this transition. I set out to rectify it with one student. First, the normal use – a pulling motion that is used to unbalance and toss the partner into the distance. Not frightening stuff. Quite tame, possibly even lame.
Now the alternate demo with an infusion of the seemingly unimportant turn that is the key to using conservation of angular momentum. One small turn and my student went accelerating towards the wall, moving at a speed that caused his face to lunge towards the frame of his spectacles. I had to break my own balance to arrest his acceleration as I didn’t want to risk an A&E visit should he crashed hard into the wall.
But its a good demo, quite a thrill somewhat like sitting in a roller coaster accelerating on the down slope.
