Continuum (Ligeti)
Continuum for harpsichord is a musical composition by György Ligeti composed in 1968, and dedicated to the contemporary harpsichordist, Antoinette Vischer. The composer describes the conception and result of its technique: Amy Bauer (2004, p. 130) describes the piece as "trompe-l'œil", creating "a sense of stasis through extremely rapid activity." She compares it to a patient's description of the schizophrenic experience of, "an intense cerebral activity in which inner experiences took place at greatly increased speed, so that much more than usual happened per minute of external time. The result was to give an effect of  slow motion." (Sass 1992) This piece has also been arranged for barrel organ and for two player pianos by the composer. The piece has also been compared by classical music reviewers to the magnetic fluctuations of comet 67P/Churyumov–Gerasimenko as detected by the space probe Philae after the fluctuations were artistically sonificated by a German composer and sound designer to make them audible.
