What Are Chord Progressions?

A chord progression is a sequence of chords played in order. Chord progressions are described using Roman numerals — I, ii, iii, IV, V, vi, vii° — where each numeral represents a chord built on the corresponding scale degree. This notation is key-independent: a I–V–vi–IV progression is the same harmonic relationship in G major (G–D–Em–C) as it is in C major (C–G–Am–F).

Uppercase numerals (I, IV, V) indicate major chords; lowercase (ii, vi) indicate minor chords; vii° indicates diminished. Jazz and R&B extend this with 7th chord notation: ii7, V7, Imaj7. The Roman numeral system lets musicians discuss harmony in any key using the same vocabulary.
