The Marriage of Figaro
The Marriage of Figaro (, ), K. 492, is an opera buffa (comic opera) in four acts composed in 1786 by Wolfgang Amadeus Mozart, with an Italian libretto written by Lorenzo Da Ponte. It premiered at the Burgtheater in Vienna on 1 May 1786. The opera's libretto is based on a stage comedy by Pierre Beaumarchais, "La folle journée, ou le Mariage de Figaro" ("The Mad Day, or The Marriage of Figaro"), which was first performed in 1784. It tells how the servants Figaro and Susanna succeed in getting married, foiling the efforts of their philandering employer Count Almaviva to seduce Susanna and teaching him a lesson in fidelity.
Libretto
By the 20th century some librettists became recognised as part of famous collaborations, as with Gilbert and Sullivan or Rodgers and Hammerstein. Today the composer (past or present) of the musical score to an opera or operetta is usually given top billing for the completed work, and the writer of the lyrics relegated to second place or a mere footnote, a notable exception being Gertrude Stein, who received top billing for "Four Saints in Three Acts". Another exception was Alberto Franchetti's 1906 opera "La figlia di Iorio" which was a close rendering of a highly successful play by its librettist, Gabriele D'Annunzio, a celebrated Italian poet, novelist and dramatist of the day. In some cases, the operatic adaptation has become more famous than the literary text on which it was based, as with Claude Debussy's "Pelléas et Mélisande" after a play by Maurice Maeterlinck.
