Chopin's 24 Preludes, Op. 28, are a set of short pieces for the piano, one in each of the twenty-four keys, originally published in 1839.
Chopin wrote them between 1835 and 1839, partly at Valldemossa, Majorca, where he spent the winter of 1838–39 and where he had fled with George Sand and her children to escape the damp Paris weather. In Majorca, Chopin had a copy of Bach's The Well-Tempered Clavier, and as in each of Bach's two sets of preludes and fugues, his Op. 28 set comprises a complete cycle of the major and minor keys, albeit with a different ordering.
The autograph manuscript, which Chopin carefully prepared for publication, carries a dedication to the German pianist and composer Joseph Christoph Kessler. The French edition was dedicated to the piano-maker and publisher Camille Pleyel, who had commissioned the work for 2,000 francs (equivalent to nearly $30,000 in present day).
