Fryderyk Franciszek Chopin,was a Polish composer and virtuoso pianist of the Romantic era, who wrote primarily for the solo piano. He gained and has maintained renown worldwide as one of the leading musicians of his era, whose "poetic genius was based on a professional technique that was without equal in his generation." Chopin was born in what was then the Duchy of Warsaw, and grew up in Warsaw, which after 1815 became part of Congress Poland. A child prodigy, he completed his musical education and composed many of his works in Warsaw before leaving Poland at the age of 20, less than a month before the outbreak of the November 1830 Uprising.

The Waltz in A-flat major, Op. 69, No. 1, is a waltz composed by Frédéric Chopin in 1835. It was posthumously published by his friend Julian Fontana in 1855, six years after the composer’s death, together with the earlier composed Waltz Op. 69, No. 2. It is also called "The Farewell Waltz" or "Valse de l'adieu". The waltz was originally written as a farewell piece to Maria Wodzi?ska, to whom Chopin is said to have been engaged. This autographed copy Pour Mlle Marie, given to her in Dresden, Germany, in September 1835 is now lost. Another autographed version of the piece he dedicated in 1837 to Eliza Peruzzi. A third autograph, held by the Bibliothèque Nationale de Paris, Chopin dedicated 1842 to Mademoiselle Charlotte de Rothschild. Various copies of this waltz exist, among them one presented as the posthumous edition of Julian Fontana, but it has not been substantiated by any known autograph.

The waltz is in A-flat major, with a time signature of 3/4. The tempo is marked at tempo di valse, or a waltz tempo. The beginning theme, marked con espressione, is melancholic and nostalgic, and reaches a small high point with a fast flourish. The second part is marked sempre delicatissimo, or con anima in other versions. It is somewhat more cheerful than the previous theme, but soon gives way to the same first theme. After a second rendition of the first theme is a third theme, marked as dolce, the most playful theme. It leads to another theme with a series of ascending double-stops. This fourth theme is marked poco a poco crescendo, with other editions adding ed appassionato. This leads back to the third, playful theme, and returns to the beginning with a da capo al fin.
