“Threnody To The Victims of Hiroshima”by Krzysztof Penderecki

“4’ 33”by John Cage

John Cage's most famous musical composition is called 4'33".

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.

"I have nothing to say, and I am saying it, and that is poetry as I needed it"

-- John Cage
