One immediate corollary of this is that the artist cannot have an intention he or she wants to get across, nor can it be a matter of expressing an emotion or of moving an audience emotively. The artwork is then a happening experienced variously and disparately by an audience. The audience, as the word says etymologically, is originarily aural, not visual. The viewer is rather the suitable title for the one experiencing a metaphysical artwork. The artwork happens at various independent points and is experienced at various independent points by the audience.
Events overlap and interlace and interact without impeding each other.
There is no unified meaning to be culled from a performance. In particular, it does not tell a story. It is consistent for Cage, the first performance or happening artist, to have moved freely beyond the bounds of music to painting, film, theatre and dance because the postmetaphysical artwork is not primarily what has been brought forth, and thus not definable in terms of a medium, but is rather the setting up of an open timeframe for an event or events. This setting up is not a presentation of something already imagined. Composer who no longer arranges sounds in a piece, simply facilitates an enterprise.
