Remarks

Name writes each chord with the quality its degree has in the mode — upper case for major, lower for minor, ° for diminished, + for augmented, an accidental where the degree differs from the major scale's — so a reader can check the label against the scale. A few named progressions borrow a chord from a neighbouring mode and are named for it: the Aeolian "Andalusian cadence" ends on the harmonic-minor V, the harmonic-minor "Harmonic descent" passes through the natural-minor bVII, the Phrygian dominant "Spanish vamp" and "Phrygian descent over a major tonic" take their bIII, bVI and bVII from Phrygian, and the Lydian dominant "Fusion vamp" its bVII7 from Mixolydian. The tables used to write "vii°" for the minor seventh-degree triad of Lydian and describe the Dorian ii as major.
