I am trying to analyze the chord structure of a song (not for any real purpose, just for the sake of better understanding) from the Destiny Taken King Soundtrack called Traveler's Promise. I am trying to figure out what is going on at 2:05 in the link.
Just before this section, the song is playing around in D Dorian. With this section, we have this chord progression:
Gm, G♭m, Am, A♭m, Bm, B♭m.
My question is two-fold:
- Should the penultimate chord more properly be referred to as Bm or C♭m?
- Is it still worth thinking about this in the key of D minor, or has it changed center, or has a center been entirely lost in the modulation?
