So, I come across this progression fairly often: e.g: G - A - C
I was wondering if this progression has a name since its used often in pop songs. I interpret it as V - VImajor - I. Scales to use vary from Gminor pentatonic, to G lydian dominant - A mixolydian - C mixolydian. I am not that familiar with chord scale theory and was wondering how one would fit chord scale theory over this kind of progression?
Edit: after some comments I want to re-evaluate my previous statement about the interpretation of the progression. The progression drwas heavily to G, making it plausible that G is the I chord, making the progression I, IImajor, IV. Either case, the A is the odd one out. How does the A fit in this progression?
