Live On Forever by The Afters has a "chord" progression that continues throughout the entire song, but each "chord" only has two notes, which are:
C, E♭; (must be Cm, the only chord that works)
E♭, G; (E♭ or Cm, probably Cm because the "C" note from before seems to be sustained into this "chord")
G, B♭; (Gm or E♭)
F, B♭; (must be B♭)
F, A; (Dm or F)
How would you name these? The chords I would name it is Cm, Cm, E♭, B♭, F
It really tricked me because it's in C "dorian" (so its key signature resembles B♭ but ends on a C note), and there are no accidentals in the entire song, so the possible chords are F, B♭, E♭, Dm, Cm, and Gm.
If you want to listen to it, it's clearest at the very beginning.
