Roger Sayer plays the Fugue of Bach's St Anne Prelude and Fugue, BWV 552.
The work takes its moniker from a hymn tune of the same name by William Croft, however it is unlikely that Bach would have been aware of this tune. Like the Prelude, commentators have interpreted the number three (in particular the three sections of the Fugue) as Bach's deliberate portrayal of the Trinity in music.
