While playing a game of Forbidden Land this evening, we had Arthur Rubenstein play a series of Chopin Nocturnes via Youtube. I listened out to see which would ‘change’ key. D flat major, B major x2, E major, A flat major, and E minor were up a semitone and thus altered in feel. F major, G minor, E flat major, and F minor did not shift.
