History

Prelude in C major, BWV 846 belongs to the first book of The Well-Tempered Clavier. Bach's collection fair copy is dated 1722. For many years its life was in manuscript: around 1800, publishers in Zurich, Bonn and Vienna/Leipzig brought competing editions into print. That long journey from manuscript to publication is part of this piece's wider history. An earlier, shorter form of this C-major Prelude appears in the notebook used for Wilhelm Friedemann's lessons. Its family teaching roots are a different historical layer from the later collection fair copy.

What to listen for

  1. Hear a small change inside the pattern

    Across these three bars, the upper figure keeps G and C before changing its higher note from E to F; the following bar changes C to B. Listen for how small pitch changes reshape the harmony.

  2. Notice the pattern opening into the ending

    The final two moving bars no longer repeat the same half-bar figure. Their flowing notes lead to a sustained, arpeggiated chord with a fermata. Let the change in texture make the ending audible.

How to practise it

A familiar pattern still needs an even pulse and a sense of where the harmony is going.

  1. Keep the small notes even without rushing the second half of each bar.
  2. Preserve the held lower notes while the moving figure continues.
  3. Listen for changes in harmony, so repeated shapes do not all sound alike.

How hard is it

Level 4, estimated

A recurring accompaniment pattern may ease initial reading, while harmonic direction, consistency and connected sound still require deliberate control.
