I think its one, if not the most beautiful sonata of Beethoven.
Also known as tempest 3rd movement (appear in the 2012 movie Total Recall).
Sadly, the only music box i own is the kikkerland. And i cannot continue with the music, because the next phase would need to go to a higher octave, and C6 is the max this thing can go, so i can't finish this peace. Feel free to use it as you wish, once i'll get my hand on a 30 note box i'll finish it.
