@mandlebro also I've heard that the reason for that weird end to that sonata is due to him being aware it needed to be performed for an audience, and there was no way he could allow the Funeral March be the end of the sonata because its so depressing sounding that it would be bizarre for audience to want to applaud it, so he needed a piece that was moody and virtuoso-style but not too thematic to give them something to applaud for
