(Produced by BBC 4) Renowned pianist and conductor Daniel Barenboim's masterclasses on Beethoven's piano sonatas were recorded at Symphony Hall, Chicago this January.
The featured works are: the first movement of the Appassionata Sonata, Op 57; the first movement of the Tempest Sonata, Op 31 No 1; and the third movement of Sonata Op 109.
Barenboim takes each player through their chosen sonata movement, illustrating the importance of structure and the relationships between tempo, harmony and dynamics.
