Prelude and Fugue in B-flat minor, BWV 867

The Prelude and Fugue in B-flat minor, BWV 867, is a keyboard composition by Johann Sebastian Bach. It is the 22nd prelude and fugue in the first book of The Well-Tempered Clavier, a series of 48 preludes and fugues by the composer. It was composed in 1722 or earlier.^[1]

Prelude

The prelude is in the style of an arioso, with up to seven nominal voices manifesting in only three distinct strands. The prelude's structure is bipartite, divided in half by a cadence. British music critic John Alexander Fuller Maitland compared it with the St Matthew Passion.^[2]

Below are the opening bars of the prelude:

Fugue

Among the fugues in The Well-Tempered Clavier's first book, BWV 867's fugue is the closest to stile antico. The fugue is in five voices, and its subject stands out for its use of a wide minor ninth interval^[3] and "rhetorical" pause. Instead of substantial episodes, there are only two canonic bridges. The fugue climaxes in a five-part stretto before ending on a Picardy third.^[4]

Below are the first two statements of the subject in the fugue's opening:
