What I–ii–IV–vi means

Every song below plays chords built on these scale degrees: I = degree 1, ii = degree 2 (minor), IV = degree 4, vi = degree 6 (minor) — 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.

🎭 Character: vi shares two notes with I and is one of the most common substitutions in tonal harmony — swapped in for I, it gives a softer, more wistful landing instead of a full resolution. The ii chord is the classic predominant — it sets up V the way IV does, but with a softer, more minor-key lean on the way there. IV (the subdominant) is what produces a plagal, hymn-like “amen” cadence when it resolves straight to I, skipping V entirely.
🔄 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.
