About the piece
D minor's restless energy — a miniature toccata.
D minor was Bach's key of agitation and drama, the key of the famous Toccata and Fugue and the Chaconne for solo violin. Even in this small teaching piece, BWV 935 carries that character: the opening gesture has a forward-thrusting energy absent in the C-major and C-minor preludes, and the modulation through F major (the relative) feels like a brief exhale before the piece presses back toward its tonic.
The piece belongs to the same pedagogical cluster as BWV 924–943, written to give young keyboard students a variety of keys and affects in easily digestible doses. Its compact binary-like structure — a gesture, a harmonic excursion, a return — is a blueprint for countless larger Bach movements compressed into a single page.
Practice path
Start with the opening gesture and nail its rhythm.
The opening figure sets the rhythmic character for the whole piece. Practice it hands together from the very first bar at 60% tempo, making sure the short-long or upbeat-accent patterns are crisp before moving forward. Once the opening is solid, the rest of the piece follows its logic naturally.

How to use this V1
Lean into the forward energy without rushing.
D-minor pieces invite rush: the energy pulls you forward. Counter this by placing the tempo slider at 75% and listening to whether each beat lands exactly in place. Mark the measure where F major arrives and play just that transition five times — the harmonic shift is the piece's dramatic apex and deserves precise timing.
