About the piece
D major's brightness — a prelude in fanfare mode.
In Baroque keyboard music, D major was associated with trumpets and ceremonial brightness — the key of royal fanfares and celebratory concertos. BWV 936 picks up that energy at a keyboard scale: the right-hand figures are wide-spanning and declarative, the harmony moves with confident steps through D major's closest relatives, and even the cadences feel like small flourishes rather than arrivals. Paired in the collection with its D-minor neighbor, the contrast is instructive: same tonic pitch, radically different affect.
The piece likely dates from Bach's Cöthen period (1717–1723) when he was composing prolifically for keyboard and producing much of the pedagogical repertoire associated with his children's education. Its cheerful brevity made it a perennial favorite in keyboard anthologies for the next two centuries.
Practice path
Let the wide intervals ring — resist clipping them short.
The wide-spanning figures in the right hand tempt players to shorten the longer notes to prepare for the next leap. Resist this: hold each note its full value and let the hand travel in the air, arriving precisely on the next note. This gives the piece its fanfare-like breadth.

Questions
Before you practice.
Short answers for learners and for searchers deciding whether this is the right version to start with.
01How does Bach's Little Prelude BWV 936 differ from BWV 935?
BWV 936 is in D major and introduces clearer two-voice imitation, which makes it slightly more demanding musically than the single-melody style of some earlier Little Preludes. It sits at late-beginner rather than early-beginner level.
02What does BWV 936 prepare a student for?
It is a natural stepping stone toward Bach's Two-Part Inventions — particularly the D major and D minor inventions — because it uses the same imitative two-voice texture in a shorter, more forgiving format.
How to use this V1
Practice the large leaps in isolation before tempo work.
Extract any measure with a span larger than an octave and practice the hand position shift — stop, place, play — ten times before attempting it at speed. At 80% tempo, the leaps should feel choreographed rather than grabbed. The loop tool makes it easy to repeat just those measures repeatedly.
