The way to write American music is simple. All you have to do is be an American and then write any kind of music you wish.
Quoted in Machlis Introduction to Contemporary Music (1963).
I got myself into a lovely little shall we say controversy with André Breton, by pointing out that the discipline of spontaneity, which he was asking his surrealist neophytes to adopt, was new for language but something that composers had been practicing for centuries.Virgil Thomson
Porgy is…an interesting example of what can be done by talent in spite of a bad setup. With a libretto that should never have been accepted on a subject that should never have been chosen, a man who should never have attempted it has written a work that has a considerable power.Virgil Thomson
