DLA 69.930/12 Handwritten letter from Schenker to Halm, dated April 3‒4, 1924

In response to matters raised by Halm in two previous letters, Schenker discusses figuration, distinguishing between that which works only on the surface and that which arises out of the middle and background, drawing on primal intervals. He also concedes that he heard Bruckner improvising, and criticizes it adversely. He refers to Reger, and outlines plans for forthcoming volumes of Der Tonwille.
