borrowed chords are actually very common in all styles of music, but for whatever reason I don’t “feel” them as innately. I don’t know if this is true for others, but it’s probably mostly just me. all the more reason to listen to more new music and train the ear!

compare the following

all within the key: Emin G D Amin

with E G D Amin

or Emin G D A

or even E G D A

creating distinctly different harmonic characters
