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
editPrelude
editThe 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 in the alto (theme I extended), second subject in the 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]

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]
