Oh my goodness. Why would anybody want to kill themselves trying to learn that :happy:
I jest. But, honestly, I said the same thing when I heard the Barber piano sonata. Upon listening to it again, I liked it even more. And the next time, more. It's not one of my favorite pieces, but I can appreciate it for what it is and admire it's qualities. I think your piece has the same effect.
Although a little more off of the tonal center, your piece reminded me a lot of the Prokofiev toccata (at least your faster second part did).
What an experience if this was ever to be performed live!
Always appreciate your compositions, Nikolas.
EDIT: Also, this piece distinctly reminds me of the Stravinsky quote where he treated the piano like a percussive instrument, because that's exactly what it is.
