This week we look at CPE Bach's music and reputation in the light of the sensational rediscovery of much his archive in 1999. Throughout the week we'll hear recent recordings of this 'new' music. In this episode, Donald Macleod explores contemporary angles within CPE Bach's life and music, as well as his life at court in Berlin.

Carl Philipp Emanuel Bach was many things in his lifetime: composer, virtuoso harpsichord player and improviser extraordinaire, author, businessman – publishing his own music – biographer – of his father and other members of his family, and teacher. As the growing amateur tradition of music making among the middle classes required pieces that were playable domestically, Bach was quick to appreciate the potential for him to fill the gap.

Publishing rivalled composition and performance for importance in his professional life. Much like musicians using crowd-funding sites today, Bach introduced a subscription system for his fans, in which each work's printing and distribution was financed by prepublication sales. Haydn, Mozart, Weber and Beethoven all studied Bach's Essay on keyboard playing attentively. It's a practical guide for performers, with chapters on ornamentation, performance and improvisation.
