The second son of the great J. S. Bach and his first wife, Maria Barbara, Carl Philipp Emanuel Bach was recognized as one of the greatest harpsichordists of his time. After university study, he became harpsichordist to the Crown Prince of Prussia (later Frederick the Great), and left his service in 1767 after the death of his godfather Telemann, whom he succeeded as director of music for the five city churches of Hamburg.
Of great significance, was C.P.E. Bach's compositional output being perceived as a genuine bridge between the Baroque and Classical.
C.P.E. Bach was well known for his interpretation of ornaments. An ornamentation chart is included in the PDF version of this OSA score to assist in the very specific ornamentation included in this concerto.
