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 in A major, D 664 (Schubert)
The A major sonata is straightforward, with a dulcet melodic opening. It was the first of Schubert's piano sonatas where the sonata form as perfected by his idol, Beethoven, does not seem wrestled with; rather, it is a "joyous breakthrough", a carefree triumph over strict rules of construction.
