How to use these chords

  • I, IV and V (D♭, G♭, A♭) are the primary chords. Together they contain all seven notes of the scale.
  • vi (B♭m) and iii (Fm) each share two notes with I, and ii (E♭m) shares two notes with IV, so these minor chords often stand in for them.
  • V7 (A♭7) contains the leading tone, C, which pulls up to the root, so it resolves strongly to I. vii° (Cdim) has the same upper three notes as V7 and is mostly used as a passing chord.
  • Common progressions, in Roman numerals: I V vi IV (D♭, A♭, B♭m, G♭); I vi IV V (D♭, B♭m, G♭, A♭); ii V I (E♭m, A♭, D♭); ii7 V7 Imaj7 (E♭m7, A♭7, D♭maj7).
