Am7 is already in key
Em11(b9): E, G, (B), D, F, A
Cmaj9: C, E, G, B, D
G7: G, B, D, F

The key is Am, but what scale would fit this sequence?
Nope. It's A minor / A Aeolian. A minor pentatonic = A C D E G

Just, no. Locrian should be treated like that gay cousin. Just avoid him cuz he's weird, unstable, and is attracted to the wrong thing.

Big deal, I bought a hamster once and they put that in a box...doesn't make it a scale.
