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. 29 (Beethoven)
Ludwig van Beethoven's Piano Sonata No. 29 in B major, Op. 106 (known as the "Große Sonate für das Hammerklavier", or more simply as the Hammerklavier) is a piano sonata that is widely viewed as one of the most important works of the composer's third period and among the greatest piano sonatas of all time. Completed in 1818, it is often considered to be Beethoven's most technically challenging piano composition and one of the most demanding solo works in the classical piano repertoire.
The first documented public performance was in 1836 by Franz Liszt in the Salle Erard in Paris.
