Trying to harmonically analyze the first 9 measures of Muse's United States of Eurasia, arranged by Mathieu Hussong. I've come across a few ambiguous chords, and I can't identify correctly the progression.
Saying the tonal center is Eb
gives a reasonable progression Eb -> Eb7 -> Eb7b -> Eb6(omit 5) -> Ab9
, i.e. I -> IV
, on the first phrase (bars 1-4) but this means the second phrase (bars 5-8) is a Eb -> Eb7 -> Eb7b -> Eb6(omit 5) -> Bb/F -> Fm7
, or I -> V -> ii
which is a bit weird to me.
Saying the tonal center is Cm
and saying it's substituting Cm
by its III
(Eb
) makes this second progression a lot more simple III -> VII -> iv
, but I'm not satisfied by this interpretation either.
What would be the correct way to interpret these progressions?
