Piano Sonata no. 52 in G major, Hob. XVI:39

The Piano Sonata in E♭ major, Hob. XVI/52, L. 62, was written in 1794 by Joseph Haydn. It is the last of Haydn's piano sonatas, and is widely considered his greatest. It has been the subject of extensive analysis by distinguished musicological personages such as Heinrich Schenker and Sir Donald Tovey, largely because of its expansive length, unusual harmonies and interesting development. The sonata is sometimes referred to as number 62 based on the numbering of Landon instead of the numbering of Hoboken.
