If 4'33" captures those emotions then every piece of music captures every random, unrelated emotion that a person happens to feel while listening to it.
I strongly disagree. 4'33'' leaves much more open spaces for the listener. Whenever a listener actually hears a certain kind of music with a certain tonal material, he will automatically associate other things with it. When he/she hears a slow piece of music in a minor key and has a Western musical background, he might associate rather sad moods with it. 4'33'' doesn't do that. It leaves the listeners alone to listen into themselves.
It personally strikes me as pointless to listen to 4'33" any other way than closely.
Why do you think that? From your previous posts it rather seemed as if you had trouble getting into the piece that way.
The random sounds of X number of people all gathered together in a room trying to respect a performer who isn't, at the moment, playing anything, could have been really interestingly incorporated into a larger work. But that's the most interesting thing about the piece and it's not even what it's about, and then of course there's not anything to contextualize those random sounds, either.
Why do you think it would have been more interesting when included within a larger work? The sounds are contextualized by yourself and your surroundings (by the reality if you wish). Just because the composer isn't responsible for the context doesn't mean that the sounds don't have any context at all.
