What can I say about John Cage’s 4′33″? Pretty much anyone can play this anytime.
It consists of the pianist going to the piano, and not hitting any keys for four minutes and thirty-three seconds. (He uses a stopwatch to time this.) In other words, the entire piece consists of silence or rests.
On the one hand, as a musical piece, 4’33” leaves almost no room for the pianist’s interpretation: as long as he watches the stopwatch, he can’t play it too fast or too slow; he can’t hit the wrong keys; he can’t play it too loud, or too melodramatically, or too subduedly.
On the other hand, what you hear when you listen to 4’33” is more a matter of chance than with any other piece of music — nothing of what you hear is anything the composer wrote.

Next time you come to a lesson and haven’t practiced, just tell me you’re playing Cage’s 4’33”!
