The excellent composer Marcus Maroney, whose own music reminds me of Frank Martin's insofar as it doesn't quite remind me of anyone else's, has gently amplified my Martin post below, noting that the genial Swiss wasn't quite a twelve-tone composer (in the doctrinaire sense) as I had originally made out. The wording has been tweaked. Also, I've dredged up an old New Yorker column pairing Martin with the equally fascinating and elusive Ferruccio Busoni; you can read it here.
