OJ 6/7, [18] Handwritten letter from Schenker to Moriz Violin, dated February 22, 1925

Schenker thanks Violin for his recent letter (and enclosure), which contains evidence of Hertzka's false calculations of subscriptions to Der Tonwille – this letter in stark contrast to the actions of his pupils Weisse and Brünauer, who had given more support to the publication of Weisse's recently published vocal quartets than to his writings. Leaving Der Tonwille behind, which has earned him little money and caused him much misery, he has written a lengthy study of Bach's solo violin works, which will be published in the first volume of Das Meisterwerk in der Musik, which will include a critique of Ernst Kurth's Grundlagen des linearen Kontrapunkts.

Gerhard Albersheim will leave a space in Schenker's calendar that Schenker offers to Erich Voss; will teach him himself because Weisse may not be up to date with Der freie Satz; Voss to contact him.
