In regards to what you said about the metronome, it is a great practice technique that I wish I had known when I played it, and it can go for pretty much every piece, like the Vitale Chaconne I am playing now: Stomping, the metronome is good but stomping from side to side in tempo brings you a whole new awareness to the little beats that you weren’t aware you were skipping or playing too many of, and it comes in great handy when you finally are at the level to play with an accompanist.
I think it’s interesting that everyone is bowing the starting chord up. The copy I have (Schirmer, 1940) directs a down bow, followed by another down bow for the next note. I don’t know if I can even play it with the up bow chord. 🙂
