A barcarolle (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.
A barcarolle is characterized by a rhythm reminiscent of the gondolier's stroke, almost invariably in 6/8 meter at a moderate tempo.
While the most-famous barcarolles are from the Romantic period, the genre was well-enough known in the 18th century for Burney to mention, in The Present State of Music in France and Italy (1771), that it was a celebrated form cherished by "collectors of good taste".
The barcarolle was a popular form in opera, where the apparently artless sentimental style of the folklike song could be put to good use. In addition to the Offenbach example: Paisiello, Weber, and Rossini wrote arias that were barcarolles; Donizetti set the Venetian scene at the opening of Marino Faliero (1835) with a barcarolle for a gondolier and chorus; and Verdi included a barcarolle in Un ballo in maschera (i.e., Richard's atmospheric "Di’ tu se fidele il flutto m’aspetta" in Act I). The traditional Neapolitan barcarolle "Santa Lucia" was published in 1849.
