A few years ago I gave a paper on the aesthetics of ‘noise,’ that is, on the ways in which non-musical sounds can be given aesthetic shape and structure, and thereby form the basis of significant aesthetic experience. Along the way I made reference to Arnold Schoenberg's musical theory, in particular his notion of Klangfarbenmelodie, literally ‘sound colour melody,’ or musical form based on timbre or tonal colour rather than on melody, harmony or rhythm. Schoenberg articulated his ideas about Klangfarbenmelodie (...) in the final section of his Harmonielehre. ‘Pitch is nothing else but tone colour measured in one direction,’ wrote Schoenberg. ‘Now, if it is possible to create patterns out of tone colours that are differentiated according to pitch, patterns we call ‘melodies’…then it must also be possible to make such progressions out of the tone colours of the other dimension, out of that which we simply call “tone colour.”’ In other words, traditional melodies work by abstracting and structuring the dominant pitch characterizing a musical sound, while ‘sound colour melodies’ work, Schoenberg argues, by structuring the combined set of pitches contained in a given musical sound. Schoenberg is emphatic that, although a neglected and underdeveloped possibility within Western classical music, ‘sound colour melody’ is a perfectly legitimate and viable form of musical expression; indeed for Schoenberg it is a musical form with enormous potential.
