Dear Bang,
Good questions all...
1) About your you have perceived the problem and described it very well. As you go through the film you will see how, after postulating the necessity of that arch, I go more and more into the problem of how to maintain it (the action of the lumbricals & interossei, the grasping action). Hopefully this will help you become more aware of what you could do in practical terms to help your own arch when it doesn't seem to want to help itself. It might even be something as simple as learning to lift your fingers in certain situations, as I show in chapter 8.
2) Your do you rotate your hand? If you let the fifth finger side of your hand drop lower than the central peak, your second finger's metacarpal-phalangeal arch, then you may well indeed be copying what you see in my film but getting yourself in trouble. Since I made the film I have further developed my understanding of the difference between the hand and the thumb. The hand's transverse arch should not slope to the outside as I show in the film: this is a mistake! The fifth finger knuckle and second finger knuckle should be more or less at the same height. The thumb functions less as a completion of the hand's arch and more as a support strut for that arch that sticks out to the inside of the hand.
On the other hand, if you rotate your hand the other way, pronating it in order to move your thumb into its key, you may be using that movement to compensate for a lazy thumb. This would make the space between thumb and forefinger collapse, allowing the side of your hand's arch to sink too low. If this is the case, your teacher is right. You have to activate your thumb's muscles, and especially that one particular muscle I show in the film, the first dorsal interosseous, to help it be a better support strut. I suspect that you are suffering from this second variant, a necessary pronation but without the necessary activity from the thumb to make it work.
3) is the way to go, and especially necessary for you because you are such a natural. You have talent, so there's a natural tendency for you to just rely on your instincts and play - but as you see, your mechanism, for all its very fine capability, still needs some education.
Thanks for some very pertinent questions, I always welcome the opportunity to clarify these complex issues. Please do let me know how things develop.
