Well, I fixed the problem by downloading Adobe (and finding the right page on imslp). I dislike Adobe because it is a huge gigantic beasthog, and when I still used Windows, I used Foxit and actually removed Adobe from my system altogether. But it seems okay so far on the Mac...
Time for WTC Project, Take II.
D minor this time, instead of B-flat minor (analysis of the sets from both books in that key).
I have recordings now - GG playing pretty much everything by Bach. He's such a weirdo...but it's hard not to like him. I like him because he made his own rules for Bach. You get tired of listening to the same thing over and over again, and sometimes subtle differences just don't cut it. If I could actually play (I can't, really), I would do things very differently from GG a lot of the time, but he is the most interesting I've found to listen to (and I'm aware that the opinion is very cliché, but am not too concerned about that).
So, since I suck at playing piano, I have never really gotten to know a lot of Bach, much to my dismay. But I have recordings that captivate me now.
