OJ 14/45, [71] Handwritten letter from Moriz Violin to Schenker, dated July 18, 1928

Owing to a "complete breakdown," Violin is recovering at a sanatorium in Schierke, from where he writes. In response to Schenker's previous postcard, Violin had written more than once to Prof. [Fritz?] Stein for the return of the manuscript of a Handel arrangement by Schenker, and he will chase him up in August. A pupil of his, Harry Hahn, has taken upon himself to lecture on Schenker's theories at the local society of composers; for this he has prepared classroom-size enlargements of voice-leading graphs of a Bach prelude and a Schubert waltz, and has proved a surprisingly competent and persuasive speaker.

The large-format graphs prepared by Harry Hahn have been greeted enthusiastically by Schenker's pupils and friends; Schenker suggests that a "light projection apparatus" (i.e. an overhead projector), which is now often available in schools and hospitals, might be more practical.
