I'm working on M0zart's last sonata and have a question which maybe someone with a better score (or better knowledge) can answer. Bar 141 of the Allegro is insanely difficult to play without a hiccup. I'he heard some pianists (including Uchida) leaving out the low D# in the LH, or in any case it very much sounded like they did. It sure makes that hellish bar a lot easier. Would this be accepted practice, or is it maybe written like that somewhere in an Urtext ?
