There are ways in which playing with the hand cupped cross-strung style — with the fingers placed 1-4-3-2 descending — is really eons more comfortable than the textbook 1-2-3-4 way. I don’t want to get too far off the reservation here, but this is shockingly more comfortable, and I think much more manageable for someone with second and third fingers hanging like elongated weeping willow branches between a thumb and a thumb-sized abortion of a fourth finger. I’m not committing to it, but I’m open to the idea of doing this for close work in the left hand. It’s also more comfortable in the right, but I can manage the textbook way in that hand.
I still play the stretched out left-hand arpeggios in the normal fashion.
We’ll see how it works out, I guess.
