Ludwig van Beethoven's Piano Sonata no. 7 in D major, one of three piano sonatas in his tenth opus, was dedicated to the Countess Anne Margarete von Browne, and written in 1798. This makes it contemporary with his three string trios opus 9, the violin sonatas of opus 12 and the violin romance that became his opus 50 when later published. (The year also saw the premiere of a revised version of his second piano concerto, whose original form had been written and heard in 1795. [1])

It is divided into four movements:

1. Presto
2. Largo e mesto
3. Menuetto: Allegro
4. Rondo: Allegro

The Opus 10 sonatas are usually described as angular or experimental, as Beethoven began moving further and further away from his earlier models. The Third sonata is the longest, and spans approximately 24 minutes. It is the only one of the Opus 10 sonatas that has 4 movements. The second movement is famous for its intimations of later tragic slow movements, as well as for its own beauty.
