<P> Chopin took the new salon genre of the nocturne, invented by the Irish composer John Field, to a deeper level of sophistication . He was the first to write ballades and scherzi as individual concert pieces . He essentially established a new genre with his own set of free - standing preludes (Op. 28, published 1839). He exploited the poetic potential of the concept of the concert étude, already being developed in the 1820s and 1830s by Liszt, Clementi and Moscheles, in his two sets of studies (Op. 10 published in 1833, Op. 25 in 1837). </P> <P> Chopin also endowed popular dance forms with a greater range of melody and expression . Chopin's mazurkas, while originating in the traditional Polish dance (the mazurek), differed from the traditional variety in that they were written for the concert hall rather than the dance hall; as J. Barrie Jones puts it, "it was Chopin who put the mazurka on the European musical map ." The series of seven polonaises published in his lifetime (another nine were published posthumously), beginning with the Op. 26 pair (published 1836), set a new standard for music in the form . His waltzes were also written specifically for the salon recital rather than the ballroom and are frequently at rather faster tempos than their dance - floor equivalents . </P> <P> Some of Chopin's well - known pieces have acquired descriptive titles, such as the Revolutionary Étude (Op. 10, No. 12), and the Minute Waltz (Op. 64, No. 1). However, with the exception of his Funeral March, the composer never named an instrumental work beyond genre and number, leaving all potential extramusical associations to the listener; the names by which many of his pieces are known were invented by others . There is no evidence to suggest that the Revolutionary Étude was written with the failed Polish uprising against Russia in mind; it merely appeared at that time . The Funeral March, the third movement of his Sonata No. 2 (Op. 35), the one case where he did give a title, was written before the rest of the sonata, but no specific event or death is known to have inspired it . </P> <P> The last opus number that Chopin himself used was 65, allocated to the Cello Sonata in G minor . He expressed a deathbed wish that all his unpublished manuscripts be destroyed . At the request of the composer's mother and sisters, however, his musical executor Julian Fontana selected 23 unpublished piano pieces and grouped them into eight further opus numbers (Opp. 66--73), published in 1855 . In 1857, 17 Polish songs that Chopin wrote at various stages of his life were collected and published as Op. 74, though their order within the opus did not reflect the order of composition . </P>
