Carl Philipp Emanuel Bach, the second surviving son of Johann Sebastian Bach, spent decades as keyboardist to Frederick the Great in Berlin before succeeding Telemann as music director in Hamburg. His volatile, quick-shifting 'empfindsamer Stil' (sensitive style) and his influential treatise 'Essay on the True Art of Playing Keyboard Instruments' made him a crucial bridge between his father's Baroque and the Classical age of Haydn and Mozart. In his own century he was often the more famous Bach.
