It appears to me that the subject of music, from Machaut to Boulez, has always been its construction. Melodies of 12-tone rows just don't happen. They must be constructed....To demonstrate any formal idea in music, whether structure or stricture, is a matter of construction, in which the methodology is the controlling metaphor of the composition...Only by 'unfixing' the elements traditionally used to construct a piece of music could the sounds exist in themselves--not as symbols, or memories which were memories of other music to begin with.
Morton FeldmanDo we have anything in music that really wipes everything out? That just cleans everything away?
Morton FeldmanMost music is metaphor, but Wolff is not. I am not metaphor either. Parable, maybe. Cage is sermon.
