7. It is revealing to compare the fictitious ciphers imposed by Forte on Schoenberg's music with genuine ciphers placed in a composition by a composer of Schoenberg's circle. See Barbara Dalen, "'Freundschaft, Liebe, und Welt': the secret programme of the Chamber Concerto," The Berg Companion, ed. Douglas Jarman, 123-140. Dalen makes an absolutely airtight case for the ciphers she finds, backed up by clear, unequivocal, documentary and musical evidence. Forte has no such support.
