Hi, Lee. Cracking website – thanks for making the effort and putting it out there.
My question: Having put together a four-chord sequence, are there any rules that dictate where the sequence might go from there? Should I write a melody line that passes chord four and gives me a clue?
I can find a chord five that fits but the sixth is another matter… 🙁
Cheers, Gary.
The AmM7 is quite unstable so without hearing how you are playing it, it’s a bit hard to tell. If you want to get back to the Em perhaps try something like Bm7 / B to lead back.
Some things to think about. D6 is essentially Bm7 inverted. B is the 5th of E so it’s an obvious choice for leading into E.
The key could possibly be thought of as D major or E dorian or E minor possibly. Maybe even G major. The AmM7 doesn’t quite belong so depends whether you think of it as minor or major, probably depends on how long you let it ring out. I would first figure out what key you feel like it should be. If E minor feels like home then it’s probably E minor or E dorian, depending on what you are doing with the A chord.
Try messing around with chords belonging to those keys and see if anything works, might give you some more ideas to work with.
