# Modes in Series

If I want to play G/A... I find the Note 'A' and think in 'Mixolydian Scale intervals. (i.e.) as if the, 'A' is the, 'G'. G,A,B,C,D,E,( flat the,7th ).IF:I think the 'Tonal Centre' is the key of 'A, however, the 'A' becomes the 'Ionian Mode Major', the '3rd, is Phrygian, and the '5th, becomes 'Mixolydian. the Question is... Is this an acceptable theoretical Solution?

• What's G/A? Generally, it's the name of aG major chord with an A bass note, not a mode at all. Perhaps you mean the G scale notes, but homing to A. This would be the Dorian of G, or A Dorian, mode-wise. Mixolydian is recognised as a mode rather than a scale. The question needs re-phrasing, I think, to get some helpful answers.

• "user33232" / I was thinking 'G Mixolydian Mode, starting in the Key of 'A Major... thus : 'G over 'A. From there, if I wanted the 'Em chord, I would reach for the 3rd, and proceed to grab the, 'Phrygian intervals, which is a 'minor. (?) My thinking seems to work on 'backing tracks'.

• @DonnGoodside this still doesn't make much sense as you write it. It sounds like you're trying to use the parallel minor of A major (A minor) to play over something in A major. I still don't see the need to bring all the different modes you mention in as they seem irrelevant to what you want to do.

• Dom ___ Assuming we all undestand that Modes are both, in Series and in Paralell... etc.., C Ionian, C Dorian, D Dorian ( vs. ) C - Ionian, D - Dorin, E - Phrygian. To my understanding, 'Any Key can play any Mode, F# Locrian, Bb Dorian, Db Mixolydian... True? Dec 4, 2018 at 19:04
