Piano Sonata No. 26 (Beethoven)

Ludwig van Beethoven's Piano Sonata No. 26 in E♭ major, Op. 81a, known as the Les Adieux sonata, was written during the years 1809 and 1810.

The title Les Adieux implies a programmatic nature. The French attack on Vienna, led by Napoléon Bonaparte in 1809, forced Beethoven's patron, Archduke Rudolph, to leave the city. Yet, there is some uncertainty about this nature of the piece — or at least, about the degree to which Beethoven wished this programmatic nature would be known. He titled the three movements "Lebewohl," "Abwesenheit," and "Wiedersehen," and reportedly regarded the French "Adieux" (said to whole assemblies or cities) as a poor translation of the feeling of the German "Lebewohl" (said heartfully to a single person) (Kolodin, 1975). Indeed, Beethoven wrote the syllables "Le-be-wohl" over the first three chords.

On the first 1811 publication, a dedication was added reading "On the departure of his Imperial Highness, for the Archduke Rudolph in admiration".

An average performance of the piece lasts about 17 minutes. The sonata is one of Beethoven's most challenging sonatas because of the mature emotions that must be conveyed throughout it. It is also the bridge between his middle period and his later period and is considered the third great sonata of the middle period.

Three movements of this sonata originally written in German and French, and the last two movements are described in German because of the unusual tempo. The translation in English shown in italic as below:

The sonata opens in a 2
4 time Adagio with a short, simple motif of three chords, over which are written the three syllables Le-be-wohl ('Fare-thee-well'). This motif is the basis upon which both the first and the second subject groups are drawn. As soon as the introduction is over and the exposition begins, the time signature changes to (alla breve) and the score is marked Allegro.
