The late piano sonatas of Beethoven are among the most amazing piano compositions ever composed. Beethoven wrote these sonatas essentially deaf, and it was this afflction that ironically motivated him to produce some of the most original, personal music of the entire 19th century. In this episode, we will be looking at the Opus 109 Piano Sonata in E Major. It is amazing how, through the course of the sonata, how he can not only develop a theme, but a simple musical interval - the third, to be exact!
