Daniel Barenboim performing the Beethoven piano sonata no. 32, opus 111, the last of Beethoven's piano sonatas. Along with Beethoven's 33 Variations on a waltz by Anton Diabelli, op. 120 (1823) and his two collections of bagatelles—Opus 119 (1822) and Opus 126 (1824), this was one of Beethoven's last compositions for piano. The work was written between 1821 and 1822. Like other "late period" sonatas, it contains fugal elements and is technically very demanding.
