A barcarolle ( BAR-kə-rohl; from French, also barcarole; originally, Italian barcarola or barcaruola, from barca 'boat') is a traditional folk song sung by Venetian gondoliers, or a piece of music composed in that style. In classical music, two of the most famous barcarolles are Jacques Offenbach's "Belle nuit, ô nuit d'amour", from his opera The Tales of Hoffmann; and Frédéric Chopin's Barcarolle in F-sharp major for solo piano. Description. A barcarolle is characterized by a rhythm reminiscent of the gondolier's stroke, almost invariably in 6/8 metre at a moderate tempo.
