This could quite possibly be in contention for the "worst topic in the history of pianostreet". Bravo, jhon, you are a tremendous failure.
I have seen Jay Greenberg played a Beethoven sonata backwords and upside down on TV. He literally took the book and turned it upside down and started playing. https://www.imgartists.com/?page=artist&id=597
that's just the theme. we're talking about literally backwards. every note.
I'm just curious what a certain piece would SOUND like if I play it (or at least sight-read) "backwards" (descending) - literally, as in you'll begin in the end-most note and you'll end at the very first note! (BTW, to the moderators, kindly MOVE this to "Performance" as I had the mistake of placing it under "Repertoire.")
