Scratched record- eternally grateful that my brain, physiologically is still healing. I can do stuff now (and with hand surgery) that I could not even comprehend 3y ago.
The recovery place I was in had an old piano. So I asked my counsellor to find and print off 'Moonlight Sonata', by Beethoven. My brain simply could not understand the notes, although I had memories of how to play the piano.
So now with my newly acquired keyboard, I can recognize the notes on sheet music muchly more betterly (erly), I still have aways to go, but there is my gratitude. The cello, mind is much more problematic, but I love it's sound.
