About the piece
A praeludium for Wilhelm Friedemann — Bach the father-teacher.
BWV 926 appears in the Clavier-Büchlein for Wilhelm Friedemann Bach, the notebook Bach began for his eldest son around 1720. Unlike the smaller Little Preludes, this Praeludium in D minor is more expansive: it has a clear melodic line in the right hand against a rolling bass, and its harmonic language is richer, with chromatic passing tones and several brief tonicizations of related keys. The piece is a step up from the most elementary pieces in the collection, suggesting it was written for Friedemann once he had already mastered the shorter preludes.
The Clavier-Büchlein is one of the most personal documents in Bach's output — a father carefully sequencing material for a gifted child, scaling difficulty precisely, inserting his own newest ideas alongside arrangements of simpler pieces. BWV 926 sits near the pedagogical apex of that collection.
Practice path
Balance the singing melody against the rolling bass.
The right hand carries a true melody here — not just figuration — and it needs to project above the left-hand accompaniment. Practice with the right hand alone at 70% tempo and give each melodic note a slight lean; then add the left hand at a quieter dynamic, listening to make sure the melody never disappears into the texture.

How to use this V1
Mark the chromatic measures and slow them down.
Identify every measure where a chromatic passing tone appears — there are several in the middle of the piece — and loop each one at 65% tempo. The goal is to hear the chromatic note as a color shift rather than a stumble. Once each spot is clean individually, chain them together at 80%.
