Pierre Beaumarchais
In 1786, Wolfgang Amadeus Mozart composed an opera, "Le Nozze di Figaro", based on "The Marriage of Figaro", with a libretto by Lorenzo Da Ponte based on the play. Several composers including Paisiello in 1782 wrote operas based on "The Barber of Seville". Rossini's 1816 version is his most successful work and still often performed. In 1966, Darius Milhaud composed an opera, "La mère coupable", based on "The Guilty Mother".
Piano Concerto No. 24 (Mozart)
Mozart composed the concerto in the winter of 1785–86, during his fourth season in Vienna. It was the third in a set of three concertos composed in quick succession, the others being No. 22 in E major and No. 23 in A major. Mozart finished composing the No. 24 shortly before the premiere of his comic opera "The Marriage of Figaro"; the two works are assigned adjacent numbers of 491 and 492 in the Köchel catalogue. Although composed at the same time, the two works contrast greatly: the opera is almost entirely in major keys while the concerto is one of Mozart's few minor-key works. The pianist and musicologist Robert D. Levin suggests that the concerto, along with the two concertos that precede it, may have served as an outlet for a darker aspect of Mozart's creativity at the time he was composing the comic opera.
