The Sinfonia from Bach’s Cantata 156 is one of my all-time favorites. Employing the vocal arioso form, Bach originally scored the movement for oboe, strings and continuo, creating a sort of instrumental aria. He later used it for harpsichord solo. Either way, the result is lovely.
Enjoy this recording featuring organist, Christian Mouyen and oboist, Pascal Jean in the Église de Saint-Astier, Dordogne, France.
