I can hear some of it in my head. This talented girl in hs used to practice that one in the music room every extra minute she got. It was too difficult for me, lots of octave chords in rapid progression.
love to hear any composer bang out their stuff on a piano.
i once thot i could make software to help composers get their music published (the parts separated. This was before i knew anything about computers). i think somebody did that. compare this version to a modern NYS*** version. It will sound sappy. For Beethoven the best we have today is Artur Schnabel or Leonard Shure.
