Chords in the Key of… Every Major and Minor Key

Every key is built from seven notes, and stacking thirds on each note gives seven diatonic chords. In a major key that means three major (I, IV, V), three minor (ii, iii, vi), and one diminished (vii°); in a minor key, three minor (i, iv, v), three major (III, VI, VII), and one diminished (ii°). Pick a key below to see its chords with Roman numerals, its scale, common progressions, and its relative key — every chord linked to full guitar voicings.

Whether you are searching for the chords in the key of C, the key of G, or the key of A minor, each page shows the exact seven chords that sound "in key" together.
