Johann Strauss II composed The Blue Danube (An der schönen blauen Donau), Op. 314, in 1866. It was first performed on 15 February 1867 at a concert of the Vienna Men's Choral Association, with words added by the association's poet, Joseph Weyl. That first performance was only a mild success; the purely orchestral version Strauss prepared for the Paris World's Fair later in 1867 made it famous.
The first waltz theme, the one on this page, rises through a D major chord in the cellos and horns, with the beat accented at the end of each three-note phrase. When Strauss's stepdaughter asked Johannes Brahms to sign her fan, he wrote down its opening bars and added "Leider nicht von Johannes Brahms" - unfortunately not by Johannes Brahms.
