Thanks Eddy for the detailed reply, and for the kind words! I'm traveling for work right now so don't have the score in front of me, but will look closer at your suggestions tomorrow night when I'm back home. A few quick comments...
Bar 13: As you approached the pinnacle of the down beat of bar 13, I felt that you did so oblivious to the implied difficulty of scaling such a mountain. Sure it's not hard for the hand, but I think the music anticipating the crest should sound with a bit of struggle.
I really like this idea! I did have in mind the importance of this opening run "up the mountain" while preparing, realizing it sets the tone for the entire movement in many ways. I tried to apply a bit of an aggressive attack as the run crests, but I hadn't thought of it as a struggle. I'll experiment with this.
Bar 20: you missed the first 1/4 note of the LH
I believe this first quarter note is tied to the previous measure in my edition, but will confirm.
Bar 134: IMO, you lose way too much steam here. There is no indicated change of tempo. You don't slow down at the diminuendo indicated in bar 191, so why here? Yes, I expect some gradual yielding of the tempo, but IMO yours is too much
Yes, I noticed this too when I listened back - much more sudden slowdown than I wanted to do. I was trying to make this whole section a "climax" for the movement, and intentionally attempted to instill some drama and intensity all the way into the Largo section. That's my excuse, anyway!
Let's just call it a sudden, extreme (unintentional) rubato.
Bar 159-170: This Allegro is really well played! In bar 169, however, you played a wrong note (by accident I hope): I think you cliped an F## (G) instead of the F on the penultimate note of the bar.
Thanks! I could never get this section exactly as I wanted ideally, but as one of the more technically challenging places in the movement (for me) I'm happy with it. Regarding the wrong note, I just listened back to it and it sounds like an F to me.
But I'll certainly check it with my piano once I'm home.
Bar 224: you dropped the last four 8th notes (i.e., the 2nd half of the bar)
Oh hell, you're probably right about this one. I have to watch myself on those repeating sections - I always want to play one too many or one too few! I'll check it out as well.
Thanks again Eddy!
