Julliard is one of the best schools in the land for the arts.
I know of two singers who were accepted there.
When this fellow has healed, physically and spiritually from that trauma, perhaps he can be a private tutor.
Or, maybe he could take a cue from Maurice Ravel, who composed a piano concerto for the left hand in D Major.
Back in 1929.
Man! The things I learn on FR! Thanks!
