¹ The sequence of writing and sending this letter is recorded as follows in Schenker's diary: OJ 4/7, p. 3890, January 14, 1934: "An Landshoff (Br. durch Peters): Dank." ("To Landshoff (letter via Peters): thanks."); p. 3891, January 16: "An Jonas (K.): Adresse von Landshoff(?)" ("To Jonas (postcard): Landshoff's address(?)") [=OJ 5/18, 35]; p. 3891, January 18: "Brief an Landshoff über Peters geschickt." ("Letter to Landshoff sent via Peters."); p. 3891, January 20: "Von Jonas (K): Landshoffs Adresse[:] war in Hamburg nur zu Besuch." ("From Jonas (postcard): Landshoff's address[:] was in Hamburg, just for a visit.").— Jonas had previously written to Schenker on December 10, 1933 (OJ 12/6, [26]), asking if Schenker had seen "die neue Ausgabe der „Inventionen“ von Landshoff mit Rev. Ber." ("the new edition of the 'Inventions' by Landshoff with critical report"). — Eight months later, Jonas wrote to Schenker (OC 44/21, September 18, 1934): "Von Landshoff kam ein langer Brief, worin er sich bedankt, um einen für ihn vielleicht leichteren Zugang zu Sch. gefunden zu haben." ("A long letter arrived from Landshoff in which he expresses thanks at having found an approach to Schenker that is perhaps easier for him."). With thanks for private communications from Michael Kassler, Darwin F. Scott, and Don C. Skemer.

² Johann Sebastian Bach. Die 15 zweistimmigen Inventionen und die 15 dreistimmigen Sinfonien im Urtext. Herausgegeben von Ludwig Landshoff. Mit Anhang: Bemerkungen zum Vortrag und Revisionsbericht (Leipzig: C. F. Peters, 1933). This work does not survive among Schenker's papers in either OC or OJ. Much of Schenker's sheet music was sold by Antiquariat Heinrich Hinterberger c. 1936: the catalog for that sale, which was in the form of a card index, has not been traced despite extensive inquiries.
