Irving Berlin couldn’t read music or play the piano in any key other than F-Sharp major. He used this transposing piano that had a hand crank to change keys. That way, he could play keys in F-sharp but the sound would move to the key of his choice. #musicfacts #pianolife #piano🎹 #pianoman #pianoteacher #pianist #piano #pianists #transposition #musictheory #keyboard🎹 #keysignature #keysignatures #musictrivia #musicians #musician #irvingberlin | David Asher Brown
