Prelude and Fugue in E-flat major, BWV 852

From Wikipedia, the free encyclopedia

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]

The prelude is 70 measures long, and consists of three parts. Measure 1-10 is a short toccata[1], establishing the tonic key (E♭), and presenting theme I. Measure 10-25 is a chorale, in the style of four-part harmony, introducing theme II. After measure 25, theme III appears, which is a double fugue made from theme I (extended) and theme II.[2][3]

This prelude is unique in the whole Well-Tempered Clavier, due to the fact that it already contains a proper fugue. Harpsichordist Pieter-Jan Belder theorises this prelude was originally written for organ.[a]

Fugue[edit]

The fugue is 37 measures long.

Notes[edit]

  1. ^ Belder considers the bass D in measure 64 too short.[1] In the organ this would not be a problem because of the pedal.
