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.
Mozart and dance
"The Marriage of Figaro" (1786) includes a crucial dance scene in which Susanna passes a feigned love note to Count Almaviva during a fandango. The dance scene was one resisted by the theatrical management at the premiere, and Mozart and his librettist Lorenzo Da Ponte prevailed only with difficulty in including it.
