The players are not able to devote their full attention to sound production, and ironically they achieve a kind of sound sound as opposed to musical sound. But it is music, of course, and a completely unique kind of music. The sounds that result are less artificial than in other kinds of music. Most music is metaphor, but Wolff is not. I am not metaphor either.
Cage is sermon.
When one knows exactly the sound he wants, there are only a few notes in any instrument that will suffice. Choosing actual pitches then becomes almost like editing, filling in detail, finishing things off. Isn't it curious that in the classical period the selection of range and timbre, i.e., orchestration, was the secondary finishing-off thing. Just the opposite. Music can imply the infinite if enough things depart from the norm far enough.
