OJ 14/45, [73] Handwritten letter from Moriz Violin to Schenker, dated October 26, 1928

Violin queries Schenker's suggestion for displaying graphic work by light-projection. He has recently made the acquaintance of a Hamburg organist name Hahnemann, who teaches only according to Schenker's theory. Finally he asks whether the "last volume" (Der freie Satz) has been published.

On his first teaching-free day, Violin writes to say that his health is good, and to wish the Schenkers a happy holiday. His organist friend Hahnemann will probably write to Schenker soon about performing some of his arrangements. Schnabel, too, wants to obtain the score, parts and cadenzas for the keyboard concertos of C. P. E. Bach that Schenker has prepared.
