- Carl Philipp Emanuel Bach (1714 – 1788) (early-music.com)
As a German composer whose early works exemplified the grandeur of Baroque style and whose subsequent works evolved into pure Classicism, Carl Philipp Emanuel Bach’s keyboard music offers a charming and historical look into the musical transition between two great eras of music history. Standing in the shadow of his famous father, Johann Sebastian Bach, C.P.E. Bach is sometimes overlooked by historians for his ground-breaking keyboard Sonatas and his significant contribution to Protestant Church music in the second half of the Eighteenth Century.
