It’s FM here — and I got ambushed by it. *sigh* I shouldn’t. I like V of V. It’s like everyone’s favorite twist.
And I think I cracked part of the whole half-step-between-1-and-2 thing on the viola, at least a little of it. I was trying to pull my hand back at the knuckles, which had the effect of separating my fingertips. I tried rolling my knuckles together (a bit like rolling the tip of your tongue), and that drew the fingertips in more closely, which helped a lot. Makes sense — if you want the fingertips closer together, then compress the hand, don’t stretch it.
