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.{{sfn|Schulenberg|1992|pp=192–193}}

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{{sfn|Ledbetter|2008|p=224}} 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.{{sfn|Schulenberg|1992|p=193}}

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

\new PianoStaff <<

\new Staff = "up"

\clef treble \key bes \minor \time 4/4

\new Voice \relative c'' {
