Your grasping question is complex. We grasp before to generate the sound. Then we grasp afterwards to support the hand in "walking" to the next note. That is why it is not a contradiction.
When I talk about the grasping action that comes a split-second after the sound, that is something else altogether. That is unhealthy, tension-generating grasping that happens too late, and that saves the hand from collapse by stiffening it. If the grasping happens on time, then it continues through the note and on towards the next note. This is elasticity at work in a good way.
I said the louder the sound, the higher the wrist. Not faster, louder.
Try to play an arpeggio with no rotation. Then try it with rotation. Which works better? The rotational movement helps everything MOVE. If the rotation replaces finger energy it is worse than useless. But if it helps the finger express its innate vitality, it is wonderful.
Great questions!
