His "Compositions 1960" includes a number of unusual actions. Some of them are unperformable, but each deliberately examines a certain presupposition about the nature of music and art and carries ideas to an extreme. One instructs: "draw a straight line and follow it" (a directive which he has said has guided his life and work since). Another instructs the performer to build a fire. Another states that "this piece is a little whirlpool out in the middle of the ocean." Another says the performer should release a butterfly into the room. Yet another challenges the performer to push a piano through a wall. "Composition 1960 #7" proved especially pertinent to his future endeavors: it consisted of a B, an F#, a perfect fifth, and the instruction: "To be held for a long time."
