Jack in the Box (sometimes seen as Jack-in-the-Box) is a work written by Erik Satie in 1899 for a pantomime-ballet (Satie called it a "clownerie", and also a "suite anglaise") to a scenario by the illustrator Jules Depaquit. Satie's intention was to score it also for orchestra. He gave it an English title because English phrases were considered fashionable in Parisian society at the time. However, after he wrote the piano score, he lost it some time after 1905. Satie believed it had gone missing on a bus and that it would never be found, but after his death it was found in his squalid apartment (some sources say it was hidden inside a notebook lodged down the back of his decrepit piano), along with the lost score for his marionette opera Genevieve de Brabant. Depaquit's scenario has not survived.
