Toccata and Fugue in E major, BWV.566

Prelude (Toccata) and Fugue in (C or) E major, BWV 566 is an organ work written by Johann Sebastian Bach probably during his four-month stay at Lübeck or afterwards in the winter of 1705–1706. It comprises five sections and is an early work in grand form of Bach.

Its compositional form resembles that of Praeludia by Danish-German composer Dieterich Buxtehude. The first section alternates manual or pedal cadenzas with dense suspended chords. The second is a fugue with much repetition following the circle of fifths. The third section is a brief flourish for manuals, ending with an even briefer pedal cadenza punctuated with nine-voice chords. The fourth section, in 34 time, is a second fugue with a rhythmic subject resembling the theme of the first fugue immediately followed by the fifth and final section that opens with a virtuous pedal-solo.
