I've been experimenting with shifting the right hand for tone, but like you, it really throws me off! I have to stop and readjust my hand, and find the strings all over again. It'll come, eventually . . .
I've been recording every song and exercise, just for my own pleasure (or torture
). It's nice to be able to go back and hear my progress, and it also ensures that I don't skip anything. Also, I'm finding when I go back to earlier pieces, they're much easier.
