I was wondering if you more theory trained indivduals could help me here. I know basic chord and scale theory. I understand that E Phyrgian is just C major played starting on an E. I also know that a C maj 7th is based on the 1,3,5, and 7th degrees of a C Ionian scale. My question is, while playing lines, over a set chord progression. How do I know which scales can be utilized over them. Espcially such things as broken scales and diminished and augmented ones. Sorry if that question seems to broad. Also, I was wondering how to immediatley distinquish between a Diatonic and the other kind (I know I sound like a goober not knowing all the terminology here ) type of chord progression.
