OJ 6/7, [50] Handwritten letter from Schenker to Moriz Violin, dated July 31, 1930

Schenker assures his friend that he understands his difficulties, and that he can be proud of holding his head high above those who do not understand music, or are incapable of interpreting it beautifully. His own problems are focussed around money, especially as his brother (Moses) has not given him the second part of his inheritance. He has sought to find cheaper ways of producing the music examples for his latest writings: he is more satisfied with the Eroica examples than the engraved illustrations from previous volumes of Das Meisterwerk in der Musik, and is planning to issue Der freie Satz with a volume of examples that is separate from the text. He repeats the news, from an earlier letter, of his being mentioned in Romain Rolland's most recent Beethoven book, and of his entry in Meyers Konversations-Lexicon, and also reports on an item about him in the Deutsche Tonkünstler-Lexikon.
