Here is another fun/interesting/odd/useful tip I learned from a professor:
Say you have these chord progressions below:
What you can do for minor chords acting as a ii, iii, or vi chord in the progression is replace them as a major chord one whole-step below while keeping the bass. So, the substitution would look like such:
Now, if we were to alter the progression from before – changing the minor chords functioning as a ii, iii, or vi – we would get these new progressions:
Some of them sound odd and funky. Personally, I preferably like the ii substitution better than iii and vi, but that is just my opinion. Feel free to try it yourself and see if it expands your harmonic pallet.
