Let's try that song again. You played it well, but try to play the second part a little faster this time.
Ugh. I already played it three times! My hands are too cold to play well.
OK, let's try another song. Play the short, slow piece that you like so much, the one that sounds like guitar music. That should warm up your hands!
Oh, that one is easy! I played it four times this morning. It's my favorite.
