Barcarolle ("Belle nuit, ô nuit d'amour") is a piece from The Tales of Hoffmann (1881), Jacques Offenbach's final opera. A duet for soprano and mezzo-soprano, it is considered the most famous barcarolle ever written and described in the Grove Book of Operas as "one of the world's most popular melodies."
The Tales of Hoffmann (French: Les contes d'Hoffmann) is an opéra fantastique by Jacques Offenbach. The French libretto was written by Jules Barbier, based on three short stories by E. T. A. Hoffmann, who is the protagonist of the story. It was Offenbach's final work; he died in October 1880, four months before the premiere.
