Prelude and Fugue in C minor, BWV 847

Prelude and Fugue in C Minor, BWV 847, is a keyboard composition written by Johann Sebastian Bach. It is the second prelude and fugue in the first book of The Well-Tempered Clavier, a series of 48 preludes and fugues by the composer.

Analysis

Prelude

The prelude is 38 bars long, and consists mostly of a repeating motif. The motif consists of running sixteenth notes in the form of broken chords in both hands. Below are the first four bars of the prelude:

${ << \new PianoStaff << \new Staff \relative c'' { \clef treble \key c \minor \time 4/4 \set Score.tempoHideNote = ##t \tempo 4 = 116 c16 es, d es c es d es c' es, d es c es d es | as16 f e f c f e f as f e f c f e f | b16 f es f d f es f b f es f d f es f | c'16 g f g es g f g c g f g es g f g | } \new Staff \relative c { \clef bass \key c \minor \time 4/4 c16 g' f g es g f g c, g' f g es g f g | c,16 as' g as f as g as c, as' g as f as g as | c,16 as' g as f as g as c, as' g as f as g as | c,16 es d es g es d es c es d es g es d es | } >> >> }$

The prelude continues like so for 33 bars, with different harmony and changes of key. The coda begins at the 34th bar, where a sudden change of texture and tempo occurs. In the first bar of the coda, an arpeggiated chord is followed by a rapid succession of thirty-second notes. This new motif is repeated twice, after which a succession of sixteenth notes ends the prelude on a Picardy third.

Fugue

The fugue is 31 bars long, and is written for 3 voices. Below is the two measure subject of the fugue, which starts in the middle voice:

${ << \new PianoStaff << \new Staff << \clef treble \key c \minor \time 4/4 \set Score.tempoHideNote = ##t \tempo 4 = 80 \new Voice \relative c'' { \voiceOne R1 | R1 | } \new Voice \relative c'' { \voiceTwo r8 c16 b c8 g as c16 b c8 d | g,8 c16 b c8 d f,16 g as4 g16 f | es16 } >> \new Staff << \clef bass \key c \minor \time 4/4 \new Voice \relative c' { R1 | R1 | s16 } >> >> >> }$

Just like most fugues in the baroque period, the subject is then repeated in the top voice in the dominant key (G minor), and then repeated once more in the lowest voice, again in the home key. The fugue then continues with a development, and then another repetition of the subject in the home key. Just like the prelude, the fugue ends with a Picardy third.
