That chaconne is one of my favorite pieces of all time. I heard it first on guitar, played by Segovia, and, probably because of that, still prefer it on guitar to the original violin. I even used to play it, pretty decently, I think.
Well, you surely also are a Sonata No.1 [BWV 1001] enjoyer, aren't you ? I find the four movement to be exceptionnally good, and they cover a lot of ground.
