Do you use the borrowed (VI) cadence?

Other Chromatic Chords

Zoon down to the bottom and you'll find "Chromatic Mediant and Coloristic Chord Usage"

Seems to me like we're borrowing triads from the minor scale.
like..

C | Ab | Bb | C
E | C | D | E
G | Eb | F | G

Which makes sense, becuase if you put a melody on top of it, I would think normally you would use the minor scale.

Or you could use a:

C,Ab,Eb,Bb progression
very standard pop progression
although the key centre is normally minor

thats my take on it

To me, this makes more sense if it is simply analyzed as a modal interchange chord (borrowed chord), with subdominant function. First, I am looking for it's acoustical pull and effect.. It's root and fifth are chromatic to the already established tonality, they inject both some interest and expectation for resolution (as less stable degrees, the chord's root has a strong pull to the fifth of the mode, and the chord's fifth has a strong pool to the third of the mode). So that's why it works.
