A Whiter Shade of Pale - Composition

Composition

The song is in moderate time in C major, and is characterised by the bassline moving stepwise downwards in a repeated pattern throughout. In classical music this is known as a ground bass. The harmonic structure is identical for the organ melody, the verse and the chorus, except that the chorus finishes with a cadence. The main organ melody appears at the beginning and after each verse/chorus. But it is also heard throughout, playing variations of its theme and counterpointing the vocal line. The vocal and organ accompaniment reach a crescendo at the beginning of the chorus "And so it was, and later ..."; where the organist rapidly runs his finger down and up the entire keyboard. The final instrumental fades out to silence - a common device in pop music of the time.

The Hammond organ line of "A Whiter Shade of Pale" came from Johann Sebastian Bach's "Sleepers, Wake!" and "Air on the G String" - both of which use a similar stepwise bass motion. The similarity is referred to in the 1982 play The Real Thing by Tom Stoppard and 1991 film The Commitments. A yet closer melodic influence that is seldom cited can arguably be found in the organ choral prelude "O Mensch bewein dein' Sünde groß" (O Man, Lament Your Sin So Great), BWV 622, from Bach's Orgelbüchlein (Little Organ Book). The music also borrows ideas from "When a Man Loves a Woman" by Percy Sledge.
