Just a quick question. So I'm watching this video about theory on Elliott Smith and the guy that made this says: "I think that the number one most important thing that you'll hear in his songs. Moving major chords in minor thirds. If you take nothing else from this video that is definitely it."
Then he gives some examples of chord progressions that do this:
Miss Misery: F major to Aflat major
Son of Sam: E major to G major
Distorted Reality: D major to F major.
Sweet Adeline: G major to Bflat major.
Now he never actually says it in the vid, but aren't all these just examples of chromatic mediants?
