Blue Danube Waltz

"The Blue Danube" is the common English title of "An der schönen blauen Donau", Op. 314 (German for "By the Beautiful Blue Danube"), a waltz by the Austrian composer Johann Strauss II, composed in 1866. Originally performed on 15 February 1867 at a concert of the Wiener Männergesangsverein (Vienna Men's Choral Association), 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!"

After the original music was written, the words were added by the Choral Association's poet, Joseph Weyl. Strauss later added more music, and Weyl needed to change some of the words. Strauss adapted it into a purely orchestral version for the 1867 Paris World's Fair, and it became a great success in this form. The instrumental version is by far the most commonly performed today. An alternate text was written by Franz von Gernerth (), "Donau so blau" (Danube so blue). "The Blue Danube" premiered in the United States in its instrumental version on 1 July 1867 in New York, and in Great Britain in its choral version on 21 September 1867 in London at the promenade concerts at Covent Garden.

When Strauss's stepdaughter, Alice von Meyszner-Strauss, asked the composer Johannes Brahms to sign her autograph-fan, he wrote down the first bars of The Blue Danube, but adding "Leider nicht von Johannes Brahms" ("Alas! not by Johannes Brahms").

The work commences with an extended introduction in the key of A major with shimmering (tremolo) violins and a horn spelling out the familiar waltz theme, answered by staccato wind chords, in a subdued mood. It rises briefly into a loud passage but quickly dies down into the same restful nature of the opening bars. A contrasting and quick phrase in D major anticipates the waltz before three quiet downward-moving bass notes "usher in" the first principal waltz melody.
