I’m confused with with what to call a chord whose quality is altered but still has the normal root note. I’ve seen this pop up several times in popular music.
Example: “Hooked on a Feeling” by Blue Swede is in the key of A-Flat Major and uses the following chord progression: Ab - Eb - Ab - Ab7 - Db - dbm - Ab - Eb
In roman numerals this would look like I - V - I - Ib7 - IV - iv - I - V.
What I’m confused about is the D-Flat minor chord. This chord I borrowed from the minor mode because I needed an F-flat to produce the minor quality. The problem is I don’t know what to call this in terms of roman numerals. I can’t say D-Flat minor is the “four” chord because D-Flat Major is the “four”. Should I say “minor four chord”, or “four chord with minor third”?
This problem arises again with major chords borrowed from other modes. “I Found A Way” (Drake and Josh Theme) is in the key of E-Flat Major and the chord progression of the chorus goes like this: Eb - F - Ab - abm. Roman numerals looks like this: I - II - IV - iv. Again, the “minor four” iv chord pops up, but as well we have an F-major chord. The person analyzing the tab could of put V/V and it still be the same chord but instead put II. The “two” chord in the major mode is usually minor, so what do we call a chord in a case like this? Should I say the “major two” chord, or the “two chord with major third”? This problem mostly happens with the III chord (also written as V/vi depending on context).
I’ll make a chart to show what happens when I try to borrow a chord from the minor mode.
Chord in C Major Borrowed from C Minor What I Say
C - I cm - i ?
dm - ii ddim - iidim ?
em - iii Eb - bIII “Flat Three”
F - IV fm - iv ?
G - V gm - v ?
am - vi Ab - bVI “Flat Six”
bdim - viidim Bb - bVII “Flat Seven”
Please help and comment. Thank you.
