What is a musical genius to do? Ludwig van Beethoven had been composing piano sonatas with his own technical prowess in mind since he was eleven years old, and thirty five years later he hits a brick wall.
The new ideas and experimentation that stimulated so much of his music wasn't happening. This was the situation Beethoven found himself in 1816. The composer was a crotchety and difficult man at the best of times and after 1815 his physical problems and lack of energy brought his compositional growth to a standstill.
