Edit: i know what modes are and how they are related to major scale..etc. question is about modal harmony and chord progression in modal harmony. not what is a mode and name of other modes..etc
What does that mean when we say a given song is in for instance in A Dorian mode?(like Beatles Eleanor Rigby)
First I thought simply we take the A Dorian scale then find the chord progression by taking every 1 3 5 interval of each note in that scale and end up with a series of chords to use in that KEY.
But later I learned that "dorian" mode is the opposite of a progression. Dorian is a "mode" (the second mode of the major scale) and implies a static harmony.
What does this static harmony mean? When I want to make a song on a specific mode, then how can I determine the usable chords or chord progression in that song? One thing I heard was I need to use unrelated chords so they don't pull your ear to a center. But how to determine in theory what is the "best" "unrelated" chords
