Why did i laugh..well what were the audience applauding?
You could argue they were applauding themselves as the 4″33 of sounds in the room at the time were the composition..i think that was the intent.
Laughter and music don’t have to mean anything to give us pleasure.
I guess it all comes down to the meaning of the piece and the meaning of art as a whole…to some a blank canvas would not be art.
In cages own words He describes music as sound and sound as music. Both are made merely of sounds, but it is our expectations that delineate music from sound, and it is the ascriptions of meaning in our listening that makes music more than it need be. Cage explains that sounds needn’t “talk”,
As a musician who has slaved over bach etc for years i see nothing musical about the piece which is what i would go to a concert for.
