So I have been experimenting with modes alot lately and have a rudimentary grasp on how there constructed but need some help on how to apply them. My first question is if you start with a C major scale, then turn that into the phrygian, which would make the root of the scale E, does that make it a C phrygian or an E phrygian? I would guess it would be an E phrygian because it becomes the root despite being composed of the C major scale. My next question is assuming I'm correct what would be the optimum thing to play in tandem with a melody derived from an E phrygian scale? So for example the guitar is playing a melody in that mode and I want to not just play the root of E on the bass what chords would work well? Should I simply bump aroud the mode as well or are there specific intervals that will sound well in various modes? My last question regards minor key signatures. The key of G major contains the same notes as the E minor scale. Does that mean that the G major scale is synonymous to the E minor scale? If so would the same notes in the key be relative major and minor? Would G,C, and D all be major in te key of E minor or is it calculated differently based off the true E minor key? Thanks for the help in advance.
