Vexations is a musical work by Erik Satie. Apparently conceived for keyboard (though the single page of manuscript does not specify an instrument), it consists of a short theme in the bass whose four presentations are heard alternatingly unaccompanied and played with chords above. The theme and its accompanying chords are written using strikingly eccentric and impractical enharmonic notation. The piece is undated, but scholars usually assign a date around 1893-1894 on the basis of musical and biographical evidence.
The piece bears the inscription "In order to play the theme 840 times in succession, it would be advisable to prepare oneself beforehand, and in the deepest silence, by serious immobilities" (Pour se jouer 840 fois de suite ce motif, il sera bon de se préparer au préalable, et dans le plus grand silence, par des immobilités sérieuses). From the 1960s onward, this text has mostly been interpreted as an instruction that the page of music should be played 840 times, though this may not have been Satie's intention.
Satie did not publish the work in his lifetime, and is not known ever to have performed or mentioned it. The piece was first printed in 1949 (in facsimile form, by John Cage in Contrepoints No. 6). The first American publication of the piece was in Art News Annual, vol. 27 (1958), again in facsimile. The first English publication was as an engraved example in an article by Peter Dickinson in Music Review, vol. 28 (1967). In 1969 the publisher Éditions Max Eschig produced the first commercial edition of the work, placing it second in a collection of three so-called "Pages mystiques". Since there is no musicological evidence linking Vexations to the other works in the volume, its appearance in that context indicates nothing more than an editor's desire to publish Satie's uncollected compositions in three-part assemblages like the Gymnopedies, Gnossiennes, etc.
Vexations appears to have had no performance history before the idea gained ground that the piece was required to be played 840 times. The first of the marathon performances of the work in this way was produced by John Cage and Lewis Lloyd at the Pocket Theatre in Manhattan by the Pocket Theatre Piano Relay Team, organized by Cage. Pianists included: John Cage, David Tudor, Christian Wolff, Philip Corner, Viola Farber, Robert Wood, MacRae Cook, John Cale, David Del Tredici, James Tenney, Howard Klein (the New York Times reviewer, who coincidentally was asked to play in the course of the event) and Joshua Rifkin, with two reserves, on September 9, 1963. Cage set the admission price at $5 and had a time clock installed in the lobby of the theatre. Each patron checked in with the clock and when leaving the concert, checked out again and received a refund of a nickel for each 20 minutes attended. "In this way," he told Lloyd, "People will understand that the more art you consume, the less it should cost." But Cage had underestimated the length of time the concert would take. It lasted over 18 hours. One person, an actor with The Living Theater, Karl Schenzer, was present for the entire performance.
