"Notable qualities of this music, whether electronic or not, are monotony and the irritation that accompanies it. The monotony may lie in simplicity or delicacy, strength or complexity. Complexity tends to reach a point of neutrahzation; continuous change results in a certain sameness. The music has a static character. It goes in no particular direction. There is no necessary concern with time as a measure of distance from a point in the past to a point in the future, with linear continuity alone. It is not a question of getting anywhere, of making progress, or having come from anywhere in particular, of tradition or futurism. There is neither nostalgia or anticipation" - Christian Wolff, 1958
