The Marriage of Figaro (play)
The play formed the basis for an opera with a libretto by Lorenzo Da Ponte and music by Mozart, also called "The Marriage of Figaro" (1786). In 1799, another opera based on the same play, "La pazza giornata, ovvero Il matrimonio di Figaro", was produced in Venice with libretto by Gaetano Rossi and music by Marcos Portugal.
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.
