German composers in the Late Baroque Era incorporated elements from German, French, and Italian styles in their compositions. Key figures included Dietrich Buxtehude, who wrote organ works based on chorales as well as praeludiums, Georg Philipp Telemann who was extremely prolific across genres, and George Frideric Handel who combined Italian and German styles in his operas and oratorios. Johann Sebastian Bach lived in several German cities over his career, was highly influential as a keyboard player and composer of cantatas, passions, oratorios and instrumental works, and incorporated counterpoint and chromatic harmony into his distinctive compositional style.
