I–II–IV–V Progression
13 songs from the corpus share this chord-degree set — open one to see and hear the real chords on an interactive fretboard.
What I–II–IV–V means
Every song below plays chords built on these scale degrees: I = degree 1, II = degree 2, IV = degree 4, V = degree 5 — 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.
