I am looking for advice in executing the following passages of fast, broken chords in Beethoven's Sonata in E Minor (Op. 90), first movement. The passages in question are pictured below.
There are general issues of accuracy and fatigue at tempo, but most specifically:
- the leap from F# back down to B in the first passage, across the mm. 55-56 (for example) bar line (circled in purple). I have trouble landing the B and/or following D accurately.
- the recurring B in the second passage. Again there are accuracy issues because of its proximity to Bb.
- also in the second passage, because of the octave it's written in, the arm angle is awkward -- even leaning well to the side, my upper arm runs into my body. When the passage is repeated in the lower octave (mm. 204-207, not pictured) that problem is effectively eliminated.
I consider "at speed" to be around quarter-note = 144bpm. I've worked slowly, experimented with a wide variety of fingerings, and I can reach all of the individual chords comfortably or with a light stretch. Nevertheless, I've hit a wall. Short of deciding this passage is beyond me at speed, suggestions ...?
