Chord Progressions

It is a sequence of chords that forms the harmonic backbone of a song. Most popular music is built from a few chords of the same key in a certain order; for example I–V–vi–IV is the progression of thousands of hits. This generator shows you the chords of any key and suggests typical progressions.

Each roman numeral represents the chord built on each scale degree. Uppercase are major chords (I, IV, V) and lowercase minor (ii, iii, vi); vii° is diminished. This notation is universal: the same progression works in any key, only the actual chords change.

The major mode sounds bright and stable; the minor, more melancholic or dramatic. Each has its own set of diatonic chords and characteristic progressions. Switching mode in the same key completely transforms the character of the music.
