Prelude and Fugue in C major, BWV 846

The A♭ may be considered as its enharmonic, G♯, which creates a major second step with F♯, but A♭ functions as an upper leading-tone (parallel natural or descending melodic minor).

[1] Arvo Pärt's "Credo" is built around Bach's C major prelude, first unravelling it through the central cacophonous twelve-tone part of the work, then remerging on the piano with the chorus and orchestra joining in harmony for the massive finale.

"Repent Walpurgis", the last track on the debut album by progressive rock group Procol Harum, contains an arrangement of the prelude by band leader Gary Brooker.

[5][6] "Fromage Frais", the sixth track on the band Union Jack's debut studio album There Will Be No Armageddon, is an Acid trance arrangement of the prelude.
