I have written a song that includes the following chords:
E major, G Major, A Major, b minor
and it also includes a little chromatic walk up going from
D to C# to C to b and then back to a main chord progression starting on E major.
These chords do not exist together in the Ionian mode. If I were in the A Dorian mode, the chords could be (using caps for major and lower for minor)
A - b - c - D - E - f# - gdim
So the chords in my song are not all in this mode, but it's close. I can't yet find a mode that combines all of these chords together.
My question therefore is two things:
1) Am I close or am I missing something altogether in terms of what key I am in?
2) For soloing, it seems like to A dorian mode would be the right choice if I'm in the right key.
Thanks ahead of time for any guidance.
