German composer, second surviving son of Johann Sebastian Bach and Maria Barbara Bach. His second name was given in honor of his godfather Georg Philipp Telemann, a friend of Johann Sebastian Bach. C. P. E. Bach 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. To distinguish him from his brother Johann Christian, the "London Bach," who at this time was music master to the Queen of England, C. P. E. Bach was known as the "Berlin Bach" during his residence in that city, and later as the "Hamburg Bach" when he succeeded Telemann as Kapellmeister there.
