Ludwig van Beethoven's Piano Sonata No. 7 in D major, Op. 10, No. 3, was dedicated to the Countess Anne Margarete von Browne, and written in 1798. This makes it contemporary with his three Op. 9 string trios, his three Op. 12 violin sonatas, and the violin and orchestra romance that became his Op. 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.
