Although C.P.E. Bach was acknowledged for his prowess on the clavichord, he was not as skilled an organ virtuoso as his father, Johann Sebastian. He wrote relatively little for the organ but around 1755 composed a sequence of sonatas for Princess Anna Amalia of Prussia, sister to Frederick II, "the Great". The works are expressive and fluid, displaying a vocal approach typical of his very best galant-style music. Featuring striking dynamic contrasts and imaginative melodic decoration they show him to be a masterful composer for the instrument.
