# Schlesinger publishes Chopin’s 24 Preludes, Op. 28 Date: 1839 ## The fact In 1839 [Chopin](/people/frederic-chopin)’s Twenty-Four Preludes, Op. 28, were published in Paris by Schlesinger, with a German parallel issue, as a printed cycle covering the major and minor keys. Much of the set had been finished in the 1838–39 Majorca winter; the public instrument stored here is the 1839 publication, not the damp cell at Valldemossa, which is a separate worsening row. French dedication to Camille Pleyel and German dedication to J. C. Kessler are title-page facts, not extra preludes. The row does not split twenty-four twins. Later complete recordings are reception. 28 (1839-09-01). ## Context A prelude before 1839 was usually a doorway into a fugue or a fantasy. Chopin’s cycle made the doorway the whole public object, ordered by key, short enough to sit on a domestic stand. That is a data-and-access claim: the cycle is a catalogue of states that can be copied. It is not a claim that 1839 tuberculosis was a compositional method. Do not treat the later Debussy preludes as this plate. A cycle that can be bought as a book is a public record of twenty-four states; it is not a weather diary and not a later complete-works reprint with another editor’s fingering. Confidence is stated on the impact path, not hidden in adjectives. Preludes print is not the Valldemossa winter. Keep illness on its own row. Mixed effects of Schlesinger publishes Chopin’s 24 Preludes, Op. 28 are separate paths. ## Evidence and sources The Institute’s works catalogue dates Op. 28 and the 1839 issues. IMSLP independently hosts nineteenth-century plates, showing the cycle as a sold book of pieces. Official: https://chopin.nifc.pl/en/chopin/dziela. Independent: https://imslp.org/wiki/Category:Chopin,_Fr%C3%A9d%C3%A9ric. The records establish opus, year, and completeness of the twenty-four. They do not establish a unique later ‘cycle listening’ survey, nor a medical dataset for the island winter, nor a claim that each prelude occupied a numbered day in a cell diary. Official or archival record: Fryderyk Chopin Institute — works and sources (https://chopin.nifc.pl/en/chopin/dziela; Narodowy Instytut Fryderyka Chopina). ## Significance Improving knowledge-record path: a closed set of short pieces became a shared reference object. High confidence on 1839 print. Modest weight: a prelude book is not a statistical office. Majorca’s damp is not added as a second publication date. The attached driver is [personal-data-protection](/drivers/personal-data-protection). The welfare reading used in this dossier is improving. That reading is an impact-path choice, not a property stored on the Fact itself. ## What is established and what is not Established: Op. 28 was published in 1839 as twenty-four preludes. Not established: that each prelude was written on a single Majorca day, or a unique modern data-protection coefficient. A contradictory first issue lacking the cycle would change the row. A later recording would not. Shared responsibility is part of Schlesinger publishes Chopin’s 24 Preludes, Op. 28. Naming Frédéric Chopin does not delete co-authors, institutions, or later transmitters. The lag from 1839-09-01 to any measured indicator is not treated as zero. Alternative explanations — weather, other armies, later statutes, or independent cultural change — remain live where the sources do not close them. 28, a demonstrated forgery of the cited carrier, or a measured series that can be argued, with lag, as a consequence of this instrument rather than of later institutions. If a number is not in the two records named above, it is not supplied here. 28 on 1839-09-01. Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts. ## People - Frédéric Chopin: https://factrail.ai/people/frederic-chopin ## Drivers - Personal-Data Protection: https://factrail.ai/drivers/personal-data-protection ## Sources - https://imslp.org/wiki/Category:Chopin,_Fr%C3%A9d%C3%A9ric - https://chopin.nifc.pl/en/chopin/dziela ## Methodology https://factrail.ai/methodology Canonical: https://factrail.ai/facts/ch-preludes-op28-1839
