The Schübler Chorales represent Bach's strategic effort to make his sacred music more accessible through marketable keyboard transcriptions, preserving complex cantata movements in simplified form for amateur organists while maintaining artistic integrity.
This chorale prelude is part of the Schübler Chorales (BWV 645-650), a collection of six transcriptions Bach adapted from his earlier cantata movements. BWV 648 reworks the soprano-alto duet from Cantata BWV 10 "Meine Seel erhebt den Herren". Characterized by intricate counterpoint and serene devotion, it transforms the vocal duet into a dialogue between organ manuals over a walking bass.
