Hello everyone! I'm writing with a question about how to improve my playing of a passage in the third movement of Beethoven's Sonata no. 23 "Appassionatta". I learned this sonata maybe 7 years ago, had a wonderful experience with it except for one awkward passage in the left hand, put it down for a few years, learned a lot more and improved my technique in general. Recently I picked it up again and am really enjoying things in the music that I missed the first time. But I'm still having a lot of trouble with that same left hand passage. Here it is. Third movement, 60 measures in or so: The problem is alternating between the outer octave and the inner chord so rapidly. I am having the devil of a time playing that pattern, and NOT the more familiar bottom note / upper chord, or bottom chord / upper note patterns. I would also appreciate suggestions for how to direct weight. Usually I'd approach a pattern like this by rocking the weight back and forth, but that's not helping here. The pattern on white notes only (D and B on the outside, F and G on the inside) works OK some of the time with an up/down movement, down on the outer notes and up on the inner notes. Thank you for any help you can provide!
