# Chopin publishes Piano Sonata No. 3 in B minor, Op. 58 Date: 1845 ## The fact In 1845 [Chopin](/people/frederic-chopin)’s Piano Sonata No. 3 in B minor, Op. 58, was published as a four-movement work dedicated to Countess Emilie de Perthuis, after the 1840 B-flat minor sonata (Op. 35) had already shocked the market with its funeral-march movement. 58 print, not Op. 35 and not a later critical edition. Chopin wrote the sonata at the Nohant-Paris hinge of the mid-1840s; engravers made the object. The row does not twin the two sonatas. Later complete sonata cycles on disc are reception. 3 in B minor, Op. 58 (1845-01-01). ## Context A piano sonata in 1845 still carried [Beethoven](/people/ludwig-van-beethoven)’s public shadow. Chopin’s Op. 58 answers with lyric movements and a finale that is not a political march. Op. 35’s march is a different opus and a different public argument. Do not merge them. Do not treat later pedagogues’ analyses as the 1845 colophon. Countess de Perthuis was a pupil-patron; she is not listed as co-author. A four-movement piano sonata in the shops is a public record of large form; it is not a funeral march from another opus and not a conservatory statute that retired Beethoven that year. Nohant quiet may be the production weather; the colophon is still a Paris-German shop object with a pupil-patron’s name on the title page. 58, 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. ## Evidence and sources BnF data and catalogues identify the Paris impression of Op. 58. IMSLP independently reproduces nineteenth-century plates of the B minor sonata. Official: https://data.bnf.fr/en/13892479/frederic_chopin/. Independent: https://imslp.org/wiki/Category:Chopin,_Fr%C3%A9d%C3%A9ric. The records establish opus and year. They do not establish a unique later sonata-recital attendance series, nor a claim that Op. 35’s funeral march is hidden inside this B minor print, nor a measured conservatory reform in 1845. Official or archival record: BnF data — Frédéric Chopin (https://data.bnf.fr/en/13892479/frederic_chopin/; Bibliothèque nationale de France). ## Significance Improving knowledge-record path: a large score entered shops as a complete argument people could copy. High confidence on 1845. Modest weight. Op. 58 on 1845-01-01. Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts. ## What is established and what is not Established: Op. 58 was published in 1845 as Chopin’s B minor sonata. Not established: that it displaced Beethoven in conservatories that year, or that Op. 35 is this print. A contradictory first issue year would change the row. 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. Confidence is stated on the impact path, not hidden in adjectives. Op. 58 is not Op. 35. Do not twin the two sonatas. Mixed effects of Chopin publishes Piano Sonata No. 3 in B minor, Op. 58 are separate paths. Shared responsibility is part of Chopin publishes Piano Sonata No. 3 in B minor, Op. 58. Naming Frédéric Chopin does not delete co-authors, institutions, or later transmitters. The lag from 1845-01-01 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. ## 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://data.bnf.fr/en/13892479/frederic_chopin/ ## Methodology https://factrail.ai/methodology Canonical: https://factrail.ai/facts/ch-sonata-op58-1845
