"Belle nuit, ô nuit d'amour" (often referred to as the "Barcarolle") is a piece from The Tales of Hoffmann, 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 text, concerning the beauty of the night and of love, is by Jules Barbier.
