Noise and message are to remain connected. In musical composition, the time when a note is not played is represented by a rest. This is a period ostensibly set aside for silence. When performers play a musical composition, the noise is there. When they do not, the noise is still there.
Noise is everywhere at every time on every channel.
The message interferes with the noise not the other way around. When a composer writes a rest he is really allowing the noise to be heard. Silence is noise. The application of chance operations to the location and selection of artworks follows the same dictum as that applied to musical composition. Rolywholyover is an isomorphic extension of Cage's metamessages to the medium of the museum.
