From Wikipedia: Carl Philipp Emanuel Bach (1714 – 1788) was a German Classical period musician and composer, the fifth child and second (surviving) son of Johann Sebastian Bach. He was an influential composer working at a time of transition between his father's baroque style and the classical and romantic styles that followed it. His personal approach, an expressive and often turbulent one known as "empfindsamer Stil" or 'sensitive style', applied the principles of rhetoric and drama to musical structures. Bach's dynamism stands in deliberate contrast to the more mannered galant style also then in vogue.
