Did you know that you can achieve a nice R&B Neo Soul sound from using slash chords (inversions) as opposed to an extended or “phat” chord?
A good trick I have discovered is to use the 11th key of the chord as the bass note and then play the chord normally. Try it to see how it sounds, the link below is for an MP3 file for the below chords.
C / Gmin7th
D / Amin7th
E / Bmin7th
Doesn’t look complex but the sound is definitely deep.
