OJ 15/16, [94] Handwritten letter from Hans Weisse to Schenker, dated March 15, 1934

Weisse apologizes for long silence, largely on account of depression at the lack of enrollment at Mannes and of enthusiasm for his recently published Violin Sonata. — At Mannes he lectures about his own work, because it is important to show how Schenkerian theory can have a practical application for composers; his pupil Israel Citkowitz is the only cause for optimism. — At Columbia University, where he "smuggles" Schenkerian theory into his lectures, enrolment continues to be large. — He sends a copy of his Violin Sonata, and promises his Variations on a Popular American Song. — He is not coming to Europe this summer. — Universal Edition is going ahead with a schools' version of Schenker's Harmonielehre, but he is surprised that Alfred Kalmus expects him to be involved in an American edition of this.

P. E. Bach’s Essay on the True Art of Playing Keyboard Instruments might be included in an Afterword to a projected English translation. — He plans an exposition of Schenkerian theory for use in schools, for which he needs to receive a copy of Der freie Satz. — He thanks Jeanette for mementos of her husband, and says a few words about his family and their summer plans.
