It is hard to believe that this highly lyrical and moderately difficult sonata of 1809 was preceded by the supremely dramatic “Appassionata” Sonata in F major op. 57 (BA 10852).
Beethoven dedicated sonata op. 78 to his pupil Therese von Brunsvick, occasionally said by Beethoven scholars to be his “immortal beloved”. It is also to her that the sonata owes its nickname “À Thérèse”.
