Piano sonatas (Beethoven)
Ludwig van Beethoven wrote his 32 piano sonatas between 1795 and 1822. Although originally not intended to be a meaningful whole, as a set they compose one of the most important collections of works in the history of music. Hans von Bülow called them "The New Testament" of the piano literature (Johann Sebastian Bach's "The Well-Tempered Clavier" being "The Old Testament").
Piano Sonata No. 6 (Beethoven)
Ludwig van Beethoven's Piano Sonata No. 6 in F major, Op. 10, No. 2, was dedicated to the Countess Anne Margarete von Browne, and written from 1796 to 1798.
