Le nozze di Figaro, ossia la folle giornata ("The Marriage of Figaro, or The Day of Madness") is an opera buffa with music by Wolfgang Amadeus Mozart and an Italian libretto by Lorenzo Da Ponte. The opera premiered at the Burgtheater, Vienna on 1 May 1786. It was well received and nearly every scene received an encore, which made the performance so long that the Emperor did not like this and wanted it to stop.
