Thanks for the comments
1) I notated the crescendos mostly so that Finale would play back the music the way I want. However, I do want to make my point clear, so I write the important stuff.
2) Definitely an interesting proposition. It's written the way it is mostly cuz it's based in the classic variations format, which works like this.
3) Indeed it is. It's what scares me

4) Thanks

5) Well, I've *always* seen variations labeled in the score, and I feel it makes it clearer.
6) True, they'll have to be slurred. I didn't so that a potential performer would have the choice of writing his own slurs.
Thanks again for the comments!
