Her first musical composition, 1955's "Secret Piece," existed only in her mind (she was unable to transcribe the notes of a bird song effectively), and, in 1968, she announced a 13-day dance festival that would take place entirely in the imaginations of anyone who participated. In 1971, she took things a step further by presenting an imaginary art exhibit at New York's Museum of Modern Art, and filmed the spectators as the real works of art.
