Chopin's Nocturne No. 2 in E-flat Major, Op. 9, No. 2, was composed in the early 1830s and is one of his most famous nocturnes. This piece was not specifically commissioned by a wealthy prince or written for a church service; rather, it was composed during a time when Chopin was building his reputation as a pianist and composer.
The nocturnes, including Op. 9, were often intended for the salon or social gatherings rather than formal concerts or church services. They reflected the Romantic ideals of the time, emphasizing expressive melody and emotion. While Chopin did perform his works in various venues, including private salons and public concerts, his nocturnes were generally more suited for intimate settings.
The work was published in 1832, and it's likely that Chopin intended for a broader audience to appreciate it, including members of the public who would buy the sheet music. Overall, it is celebrated for its lyrical beauty and expressive depth.
