Droit du seigneur
In Mozart's "The Marriage of Figaro", which premiered in 1786 with a libretto by Lorenzo Da Ponte, the comic plot revolves around the successful efforts of the young bride and groom, Figaro and Susanna, to block the efforts of the unfaithful Count Almaviva to seduce Susanna. To achieve his aim, the frustrated Count threatens to reinstitute "droit du seigneur". It was based on a play by Pierre Beaumarchais.
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.
