Opus 111

In addition to being one of Beethoven’s most emblematic works, the Piano Sonata no.32 op.111 (1821-22) is a manifesto of radical modernity. It begins the process of disintegration of sonata form, and introduces in its second movement a new method of constructing the musical phrase, to such an extent that some commentators regard it as marking the first stirrings of jazz.
