OJ 6/8, [1] Handwritten letter from Schenker to Violin, dated January 9, 1931

In this long and wide-ranging two-part letter, which includes a graphic analysis of J. S. Bach’s Two-part Invention in E-flat major, Schenker praises the work of Hans Weisse, who has recently returned from lecturing in Berlin and may be offered a post there (on Furtwängler’s recommendation), emigrate to America (with the help of Gerald Warburg), or even found an institute that would give employment to Felix Salzer and other Schenkerian disciples under one roof. — A letter from Violin, which has just arrived in the morning post, speaks of Violin’s own intention to establish a Schenker Institute in Hamburg. For this, Schenker recommends Felix-Eberhard von Cube (in preference to Reinhard Oppel) and Otto Vrieslander as possible theory teachers, if not Weisse himself. — The letter concludes with a tirade against those who have caused him financial misery (including his brother Mozio), culminating in a cynical passage in which Schenker advises his friend to look after himself and engage some dull pedagog to teach conventional theory. In the end, he wishes Violin luck with the enterprise, and thanks him for having helped rescue him from Hertzka’s clutches.
