Listening (Cage, John - 4'33")

My feelings towards this composition in a musical aspect are negative. I feel that Cage is incorrect in calling this work a musical piece. There are simply instruction on when to open the lid of the piano and when to close it. However, I do feel that this composition is an philosophic idea. I think that by just listening to the sounds around you you are able to get a random collection of noises. While Cage thought that this was music I do not. I can see how he believes that it is music, because styles such as serialism sound like random notes to the untrained ear, however they are not. I also see how if you put pitches to these random noises during 4' 33" than that might be music.
