This is Bach. And Bach, more than any other music, . . . is music complete. This doesn't just mean it's beautiful. This means you can play this music all your life, even just this Allemande, and no matter what you do, it will expose you. It will expose everything you are and everything you're not. It will expose everything you can do and everything you can't. It will expose everything you've mastered and everything you're scared of. And I don't just mean about the violin. I mean about everything. It'll show all that today, and it'll show all that when you play it again in 10 years.  And people who know music, who've seen you play it both times, they will see you play it and know who you were and who you've become.
