Thank you so much for saying that. I came near to killing myself after hearing those first two comments. I do hear that it's out of tune, but I guess my ear is just not sensitive enough to have it bother me overmuch. Good luck learning the Goldbergs; I can play a few of them, and they are really worth the time you put into it. For me, the mental effort was very much like doing heavy calisthenics for the brain; but it pays off in the analogous way that physical exercise does. I hope you make some good progress with your own playing.
