I am playing these 3 chords in the following sequence:
AM - CM - DM
What scale do they belong to?
I first thought its A Mixolydian:
// But this can't be it, because it doesn't have C#(used in A major) Dorian 1 2 b3 4 5 6 b7 Dorian A B C D E F# G
I tried to see if it fits Dorain:
//But this can't be it because it doesn't have C note(used in 2nd chord C major of the sequence) Myxolydian 1 2 3 4 5 6 b7 Myxolydian A B C# D E F# G
This seems like a usual or common sequence of chords. How can it be so complicated? Am I missing something?
