About the piece
The WTC's pastoral sprint — F major in perpetual motion.
Bach completed the first book of the Well-Tempered Clavier in 1722, assembling twenty-four pairs of prelude and fugue in all major and minor keys as a demonstration that equal temperament (or a close approximation of it) could make all keys equally usable and expressive. The F-major Prelude, BWV 856, is one of the shorter and more cheerful preludes in the collection: a stream of sixteenth notes in continuous motion, the right hand spinning arpeggiated figures while the left hand shifts harmonic positions beneath them.
It inhabits the same pastoral, easy-breathing world as F-major music generally did in the Baroque period, but the relentlessness of its motion gives it a quietly virtuosic quality — the student must sustain evenness for the entire piece without a single moment of rest. Its companion fugue is one of the WTC's more compact and playful, and the pairing of pastoral prelude with nimble fugue is one of the book's most satisfying.
Practice path
Aim for total evenness across every sixteenth note.
Set the tempo to 60% and play through once listening only for uneven notes — any sixteenth that is louder, shorter, or slightly rushed compared to its neighbors. Mark those spots and work them at 50% in isolation until each group of four sixteenths is perfectly matched in weight and duration. Unevenness hides in fast tempos but reveals itself at half-speed.

Questions
Before you practice.
Short answers for learners and for searchers deciding whether this is the right version to start with.
01How many measures is the WTC Prelude No. 11 in F major?
18 measures — one of the shortest preludes in Book I. Its brevity is deceptive: the rapid figuration requires very clean fingerwork throughout, so every bar is technically demanding.
02Is the WTC Prelude in F major BWV 856 suitable for intermediate students?
Yes, at an intermediate level. The technical demands (rapid exchange of running passages between hands) exceed what most late-beginners can manage cleanly, but the short length means an intermediate student can master it in a few focused weeks.
How to use this V1
Change hand positions smoothly without accent.
Every time the left hand shifts to a new position, there is a risk of a slight accent on the first note after the shift. Practice the left hand alone at 65%, focusing on making each position change inaudible — the bass should move like water, not step. Once the left hand is smooth, the right hand's continuous stream will feel much more secure.
