What I–bIII–IV–iv–bVI–bVII means

Every song below plays chords built on these scale degrees: I = degree 1, bIII = degree 3, IV = degree 4, iv = degree 4 (minor), bVI = degree 6, bVII = degree 7 — relative to whatever key that song is actually in. The degrees are the same; the real chords are different in every key, which is exactly why the same progression can sound totally different from one song to the next.

Closely related progressions

🎭 Character: bVI is borrowed from the parallel minor — it drops a darker, more dramatic color into an otherwise major-key progression. bIII is borrowed from the parallel minor — it's a common source of the big, anthemic lift heard in a lot of rock choruses. bVII is borrowed from the parallel minor (or heard as a Mixolydian bVII) — it's the chord most responsible for a rock or folk-rock color instead of a classical, strictly-major one.

🔄 Inversions: An inversion is the same chord with a different note in the bass — first inversion puts the 3rd on the bottom, second inversion the 5th. Try playing any chord above with its 3rd or 5th as the lowest note instead of the root: the chord itself doesn't change, but the bass line moves by step instead of jumping around, which is what makes a progression feel smoother from one chord to the next.
