Most of C.P.E. Bach's sonatas for flute and continuo date from the composer’s early creative period. While some show elements of musical Sturm und Drang, others are more galant works. All of them are true jewels of the 18th-century flute repertoire. The flutes played by Barthold Kuijken on the recording are replicas of instruments from the mid-18th century. The simple continuo instrumentation with only harpsichord (or fortepiano) places the emphasis on the imaginative little twists and turns of the flute lines.
