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".
The Marriage of Figaro
Mozart wrote two replacement arias for Susanna when the role was taken over by Adriana Ferrarese in the 1789 revival. The replacement arias, "Un moto di gioia" (replacing "Venite, inginocchiatevi" in act 2) and "Al desio di chi t'adora" (replacing "Deh vieni, non tardar" in act 4), in which the two clarinets are replaced with basset horns, are normally not used in modern performances. A notable exception was a series of performances at the Metropolitan Opera in 1998 with Cecilia Bartoli as Susanna.
