Title : Johann Strauss II , The Blue Danube WaltzDate : 1867From Wikipedia,The Blue Danube is the common English title of An der schönen blauen Donau op. 314 (On the Beautiful Blue Danube), a waltz by Johann Strauss II, composed in 1867. Originally performed 9 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 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!"The waltz originally had an accompanying song text written by Josef Weyl. Strauss adapted it into a purely orchestral version for the World's Fair in Paris that same year, and it became a great success in this form. The instrumental version is by far the most commonly performed today. An alternate text by Franz von Gernerth, Donau so blau (Danube so blue), is also used on occasion.The sentimental Viennese connotations of the piece have made it into a sort of unofficial Austrian national anthem. It is a traditional encore piece at the annual Vienna New Year's Concert. The first few bars are also the interval signal of Osterreich Rundfunk's overseas programs.It is reported by composer Norman Lloyd in his "Golden Encyclopedia of Music" that when asked by Frau Strauss for an autograph, the composer Johannes Brahms autographed Mrs. Strauss's fan by writing on it the first few bars of the Blue Danube. Under it he wrote "Unfortunately not by Johannes Brahms".The work commences with an extended introduction in the key of A major with shimmering (tremolo) violins and a French 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 3 quiet downward-moving bass notes "usher in" the first principal waltz melody.The first waltz theme is familiar gently rising triad motif in cellos and horns in the tonic D major, accompanied by harps; the Viennese waltz beat is accentuated at the end of each 3-note phrase. The Waltz 1A triumphantly ends its rounds of the motif, and waltz 1B follows in the same key; the genial mood is still apparent.Waltz 2A glides in quietly (still in D major) before a short contrasting middle section in B flat major. The entire section is repeated.A more dour waltz 3A is introduced in G major before a fleeting eighth-note melodic phrase (waltz 3B). An loud Intrada (introduction) is then played. Waltz 4A starts off in a romantic mood (F major) before a more joyous waltz 4B in the same key.After another short Intrada in A, cadencing in F-sharp minor, sonorous clarinets spell out the poignant melody of waltz 5A in A. Waltz 5B is the climax, punctuated by cymbal crashes. Each of these may be repeated at the discretion of the performer.The coda recalls earlier sections (3A and 2A) before furious chords usher in a recap of the romantic Waltz 4A. The idyll is cut short as the waltz hurries back to the famous waltz theme 1A again. This statement is cut short, however, by the final codetta: a variation of 1A is presented, connecting to a rushing eighth-note passage in the final few bars: repeated tonic chords underlined by a snare drumroll and a bright-sounding flourish.
