Cornelius Cardew - Treatise
Cornelius Cardew - treatise (1963-67)
written in the years immediately preceding his involvement with AMM, this is a beautiful work, in terms of the immediate appeal of its interpreted form to the senses, and its spontaneous yet calculated process of generation out of, not nothing, but an otherwise imperceptible sound world. it is a field of particles free floating in a much larger field of particles.
from Diaries of composer:
What I composed in this piece - the image that hovered in front of my mind's eye - was a 'Musizierweise' (Mode of music-making). I invented a way of making music and limited it to such an extent that musicians without construction ideas of their own are in a position to adopt this musizierweise.
I compose systems. Sounds and potential sounds are around us all the time - they're all over. What you can do is to insert your logical construct into this seething mass - a system that enables some of it to become audible. That's why it's such an orgiastic experience to improvise - instead of composing a system to project into all this chaotic potential, you simply put yourself in there (you too are a system of sorts after all) and see what action that suicidal deed precipitates.
