I remember reading Cage himself saying that it is about potential sound and the sounds of the audience around it when the sound is removed. He seemed to indicate that the audience noise was part of the piece.
Yes, audience noise was PART of the piece, as were environmental sounds. His instruction was to have the windows open at the concert venue for this reason. So, there's no "potential" about it, there's actual sound. If he did ever say "potential" sound, he meant in terms of exactly which sounds, not in terms of whether there would be sound. He composed the piece sometime after visiting an anechoic chamber and realising there was no such thing as silence or rather, that human's couldn't experience actual silence. This is why the piece can't be properly "performed" or recorded at many standard classical music concert venues, you need some environmental sound (inc. Audience noise). However, there was no way of knowing what that environmental sound would/will be and Cage deliberately did not specify what it should be, so it's not "sound that has been organised to communicate", it's sound that has deliberately not been organised in order to communicate.
The piece then is not about silence, it's about what we perceive silence to be and that presents a compositional problem: If we can't perceive actual silence and as you can't demonstrate this by putting the audience in an anechoic chamber, how do you use sound/music to communicate silence and then communicate that it doesn't exist? This is why the piece requires a pianist to enter the stage and sit at a concert piano as if to perform. Cage is using expectation bias, that the piano will actually be played, and therefore when it isn't played, the audience will think it's silence but because there's a deliberately noticeable amount of environmental noise they'll not actually experience silence or even what people would normally call "silence". Furthermore, Cage was not only aware that many people would not "get it" and that the piece would be highly controversial but he actually relied upon it, because he wasn't just communicating the question "how do we perceive silence" but also, the more fundamental question "what is music"? Cage was very interested in knowing what audiences would actually perceive and for this reason he (or rather his students) conducted surveys of the audiences after several of the early performances. Interestingly, it seems Cage was a little too successful at creating the expectation bias, as on more than one occasion up to a third of the audience actually believed they'd heard the piano being played very quietly!
Also, the piece wasn't just a "bolt out of the blue". A few years earlier Pierre Schafer had developed the concept of environmental noise/sound being the sole type of sound used in the compositional palette and started the movement known a "Musique Concrete". Furthermore, as the actual sound/environmental noise in 4'33" is NOT determined by the composer and not notated in the score, it is "indeterminate". And again, "indeterminacy" has a history which dates back many centuries in classical music and largely due to Cage became a musical movement in it's own right, a musical movement which included or very strongly influenced many of the other great post war composers, Stockhausen, Xenakis, Riley, Boulez, Feldman, Lutoslawski and various others. Lastly, a great work of art, music or otherwise, is largely determined by the intensity of the thoughts/emotions it evokes. Most audience members of the time did indeed have an intense reaction to 4'33", either anger from many of those who didn't "get it" or for many of those who did, "
one of the most intense listening experiences you can have".
It's easy to dismiss 4'33" as "not music", a stupid joke that any idiot could have created but it's not, it's actually a very clever composition and a sophisticated evolution of music composition techniques taken to the extreme. It's arguably not just a masterpiece but as one critic called it "
the pivotal composition of this century". Again, maybe you don't "get it", maybe you don't want to "get it", maybe you're quite happy to completely ignore it and dismiss it as "not music". That's all absolutely fine and is your choice BUT, that is a subjective opinion, you CANNOT objectively state that it is not music. And, by eliminating it and "indeterminacy" in general from your definition of music, you are eliminating whole genres/sub-genres of music, many of the greatest and most influential modern era music composers and therefore doing exactly the opposite of your own repeated advice and exactly the same as those you are criticising!! For example:
"
The series was designed to try to pry open the minds of people who listened to the same music all the time because they think that's the only thing they "like". When you analyze and think about music you can *understand* and *appreciate* it- which is a million times better than just *liking* it." - But you're not analysing, thinking about and trying to understand or appreciate 4'33" or indeterminacy in general, you're just ignoring/dismissing it as "not music".
"
You just have to be sure you have a broad enough knowledge of the subject and eliminate the bias of your own personal tastes." - So why are YOU sticking so rigidly to "the bias of your own personal tastes"/opinions (of what is and is not music) and thereby limiting rather than broadening your knowledge?
