I've found a song that uses the next progression. Is a 4 "simple" 4 bars progression:
Cm / D / D# / F
In the first 3 bars, it plays notes from this scale: D D# F# G A A# C In the last bar, basically is using the notes from the triad: F A C
At the beginning I thought it was a G harmonic minor progression, but the last bar blows my mind because it works so well but I can't fit it all together (it should be F#, not F). Is the song making a key change? or maybe I'm too tired and I can see the obvious?
Thanks to all the community in advance.
