4′33″ is a three-movement composition[2][3] by American avant-garde composer John Cage (1912–1992), says Wikipedia.

It was composed in 1952 for any instrument (or combination of instruments), and the score instructs the performer not to play the instrument during the entire duration of the piece throughout the three movements (the first being thirty seconds, the second being two minutes and twenty-three seconds, and the third being one minute and forty seconds).

Although commonly perceived as "four minutes thirty-three seconds of silence",[4][5] the piece actually consists of the sounds of the environment that the listeners hear while it is performed.[6] Over the years, 4′33″ became Cage's most famous and most controversial composition.[2]

Conceived around 1947–1948, while the composer was working on Sonatas and Interludes,[2] 4′33″ became for Cage the epitome of his idea that any sounds constitute, or may constitute, music.

A cited influence[11] for this piece came from the field of the visual arts. Cage's friend and sometimes colleague Robert Rauschenberg had produced, in 1951, a series of white paintings, seemingly "blank" canvases (though painted with white house paint) that in fact change according to varying light conditions in the rooms in which they were hung, the shadows of people in the room and so on. This inspired Cage to use a similar idea, as he later stated, "Actually what pushed me into it was not guts but the example of Robert Rauschenberg. His white paintings… when I saw those, I said, 'Oh yes, I must. Otherwise I'm lagging, otherwise music is lagging'."

Cage's musical equivalent to the Rauschenberg paintings uses the "silence" of the piece as an aural "blank canvas" to reflect the dynamic flux of ambient sounds surrounding each performance; the music of the piece is natural sounds of the players, the audience, the building, and the outside environment.
