9.3 · The Modes
The dark modes
Four modes carry the minor third, and one already has another name: Aeolian is natural minor. The other three bend it: Dorian brightens one note, Phrygian darkens one, and Locrian destabilizes the floor entirely. Every demo sits on A, so the comparison is direct.
The reference: A Aeolian
Natural minor over an A drone. The shadowed yardstick.
Dorian: raise the 6
Minor, but the 6th rises a half step. Cooler than sad. Jazz, folk, and every 'mysterious but confident' groove.
Phrygian: lower the 2
The very first step up from home shrinks to a half step. Instant Spain, instant menace.
Locrian: the unstable one
Flat 2 and flat 5: even the chord on home is diminished, so 'home' never feels safe. Composers visit; almost nobody lives here.
