I taught this at A.C.E. one summer, after randomly noticing it while planning class one morning (5 hours before the class, while driving to another class elsewhere to teach first)

Eb or D#, in all chords:

-G Aug (G B D#)
-F7 (dominant 7, for you classicals, F A C Eb)
-ebm (Eb Gb Bb)
-BM (B D# F#)
-F7
-cm (C Eb G)
-f#m Add 6th (F# A C# D#)

from REMEMBER REMEMBER from V for Vendetta, Dario Marinelli. perhaps anyone could have written it. so what. still cool. I mean, the chords, they don’t seem obviously (perhaps I’m wrong) built on movement by 5ths or 4ths… just containing Eb.
