This is definitely a favorite type of chord voicing for me. Let’s start with my YouTube playlist on the topic.
The key to understanding these chords is to know that they will feel like an unusal combination/voicing of another chord you probably know with a bass note that doesn’t seem to fit. And yet…it’s super juicy. There are lots of these out there to experiment with. I’ve written quite a few into songs that I’ve put out already, particularly on the Listener Effect Vol. 1, which is on Bandcamp if you’re interested 😉
