Happy 30th!

Daniel Barenboim performing the Beethoven piano sonata no. 30, opus 109.  Beethoven's Piano Sonata No. 30 in E major, Op. 109, is the third of his late piano sonatas (Opus 101-111) composed between 1820–1822. This sonata (composed in 1820), like the other five, shows characteristics of Beethoven's last creative phase, including rich harmonic structures, a fascination with intricate counterpoint, and strict adherence to classical and baroque forms.
