Carl Philipp Emanuel (8 March 1714 – 14 December 1788) the fifth child and second surviving son of Johann Sebastian Bach and Maria Barbara Bach, was a composer of the German Classical era. His second name was chosen in honor of his godfather, Johann Sebastian Bach's acquaintance Georg Philipp Telemann.

C. P. E. Bach was a well-known composer who lived during the transition period between his father's Baroque style and the Classical style that came after it. His unique approach, empfindsamer Stil or'sensitive style,' combined rhetoric and theater concepts to musical structures in an expressive and frequently tumultuous manner. Bach's energy contrasts sharply with the more formal Galant style that was popular at the time.

C. P. E. Bach was known as the "Berlin Bach" during his residence in that city. Later as the "Hamburg Bach" when he succeeded Telemann as Kapellmeister there, to distinguish himself from his brother Johann Christian, the "London Bach," who at the time was music master to the Queen of Great Britain. He was known as Emanuel by his contemporaries.

Bach was also a pedagogue, authoring the enduring "Essay on the real art of playing keyboard instruments," studied by Haydn, Mozart, and Beethoven.
