Andante favori

The Andante favori is a work for piano solo by Ludwig van Beethoven. In catalogues of Beethoven's works, it is designated as WoO 57.
Composition and reception.
The "Andante favori" was written between 1803 and 1804, and published in 1805. It was originally intended to be the second of the three movements of Beethoven's "Waldstein" piano sonata, Op. 53. The following extract from Thayer's Beethoven biography explains the change:
It was composed as a musical declaration of love for Countess Josephine Brunsvik, but the Brunsvik family increased the pressure to terminate the relationship. She could not contemplate marrying Beethoven, a commoner.
The reason for the title was given by Beethoven's pupil Czerny, quoted in Thayer: "Because of its popularity (for Beethoven played it frequently in society) he gave it the title "Andante favori" ("favored Andante").
The music.
The "Andante favori" is in F major (the subdominant of the "Waldstein" key), in 3/8 time, and is marked "Andante grazioso con moto". Formally, the work is a rondo, with each return of the theme appearing in varied form. The theme itself is fairly extended and in ternary form. The work takes about nine minutes to play.
Adaptations in popular culture.
The makers of the 1995 BBC adaptation of Jane Austen's novel Pride and Prejudice used the "Andante favori" as the musical content of a concocted scene in which Elizabeth Bennet and Fitzwilliam Darcy exchange tender glances while his sister Georgiana plays the andante on the fortepiano. The action of the scene is timed to match two modulations in the music, from F to D major and then back again.
