Carol, how do you know how to position your fingers if you can't remember/imagine where they go? Is music then a sequence of motions to you, sort of like a dancing with your fingers?

I do the throat-constricting thing too, at least that's how it feels. I think I'm just tightening my vocal cords to varying degrees. I can usually think a note and sing it, but sometimes I get lost. I know the next note is up, but can't remember just how far up.
