"The Blue Danube" is the common English title of "An der schönen blauen Donau", Op. 314, a waltz by the Austrian composer Johann Strauss II, composed in 1866. Originally performed on 15 February 1867 at a concert of the Wiener Männergesang-Verein, it has been one of the most consistently popular pieces of music in the classical repertoire. Its initial performance was considered only a mild success, however, and Strauss is reputed to have said, "The devil take the waltz, my only regret is for the coda—I wish that had been a success!"
