Inlcudes a Preface from Eike Fess in German, English and French.

'Here the fourths, springing from an entirely different expressive surge shape themselves into a definite horn theme, spread themselves out architectonically over the whole piece, and place their stamp on everything that happens. Thus it turns out that they do not appear here merely as melody or as a purely impressionistic chord effect, their character permeates the total harmonic structure, and they are chords like all others.'
Arnold Schonberg, Theory of Harmony, 1911
