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").
Cello Sonatas Nos. 1 and 2 (Beethoven)
Cello Sonatas No. 1 and No. 2, Op. 5, are two sonatas for cello and piano written by Ludwig van Beethoven in 1796, while he was in Berlin. While there, Beethoven met the King of Prussia Friedrich Wilhelm II, an ardent music-lover and keen cellist. Although the sonatas are dedicated to Friedrich Wilhelm II, Ferdinand Ries tells us that Beethoven "played several times at the court, where he also played the two cello sonatas, opus 5, composed for Duport (the King's first cellist) and himself". Although Jean-Pierre Duport was one of the King's teachers, it is now thought to have been his brother Jean-Louis Duport who had the honor of premiering these sonatas.
