The Flute Sonata in C Major, BWV 1033, may actually have been composed by C.P.E. Bach, rather than by his father, Johann Sebastian. Another theory is that this sonata could be a work of two different composers: Father and son? Or, teacher and pupil?
Furthermore, some scholars feel that the work is not a sonata for flute and continuo but, perhaps, a work for flute alone. The demanding flute part offers no rest for the soloist.
One of the reasons I receive so much enjoyment from the music of Bach is that none of us alive today truly knows what was going on in Bach’s day. It is fun and enlightening to consider various scenarios for why, how and when Bach made the decisions that he did. And, as far as the C Major Flute Sonata, no matter who composed it and under what circumstances, it (luckily) survives for our playing and listening pleasure!
Enjoy this wonderful interpretation by Emmanuel Pahud, flute and Trevor Pinnock, harpsichord.
