Barenboim on Beethoven - Part 1

First of two programmes in which pianist and conductor Daniel Barenboim gives a masterclass on the Beethoven piano sonatas, coaching some of the world's rising piano stars who already have international careers. Lang Lang plays the first movement of the Appassionata Sonata, Op 57, and David Kadouch the first movement of sonata Op 31 No 1. Barenboim takes each pianist through their chosen piece, illustrating the importance of structure and the relationships between tempo, harmony and dynamics.
