Prelude and Fugue in E-flat major, BWV 852

Prelude and Fugue in E-flat major, BWV 852, is a keyboard composition by Johann Sebastian Bach. It is the seventh prelude and fugue in the first book of The Well-Tempered Clavier, a series of 48 preludes and fugues by the composer.

Analysis[edit]

Prelude[edit]

Prelude, played by Kimiko Douglass-Ishizaka

The prelude is 70 measures long, and consists of three sections:^[1]

The first section begins from the first measure and lasts until m. 10. It is a short toccata^[2], mainly made of energetic semiquaver movements, with the ending two measures (m. 8 and 9) made of demisemiquavers.^[3] It establishes the tonic key (E♭), presents theme I, and ends on the dominant (B♭).^[1]
The second section starts at m. 10, and ends at m. 25. It is a chorale, in the style of four-part harmony, introducing theme II.^[4]
The third section starts at m. 25 and lasts until the end. It is a four-voice double fugue, and the first subject is introduced at alto (theme I extended), second subject at bass (theme II).^[1]^[5] This section is three times as long as the other two sections together.^[6]

This prelude is unique among the 48 preludes of the Well-Tempered Clavier, because it already includes a fully developed fugue. It may originally have been conceived for organ (the early version has fewer semiquavers in the bass of the second section than the final one).^[7]^[a]

Fugue[edit]

The fugue is 37 measures long and has three voices.^[1]

Notes[edit]

^ Harpsichordist Pieter-Jan Belder also supports this idea. He cites the example that the bass D in m. 64 is only a semiquaver, which he considers too short, and awkward. In the organ, this D can be sustained because of the pedal, but with only a keyboard (e.g. in the harpsichord), the tenor has to move on and the bass D has to be released again.^[8]
