Description

Detailed explanation Dorian is a minor mode with a natural 6th. That's its only difference from natural minor, and it's what gives a bright, un-tragic minor. The characteristic sound The natural 6th lightens the minor and removes some of the Aeolian heaviness, leaving a cool, smooth modal sound. Tonic and function The tonic is m7, but there's no required leading tone pulling to it. So Dorian is a modal center first, not a classical key. Chords and use i m7 is home, ii m7 a gentle neighbor, IV7 the signature Dorian color, VIImaj7 a modal contrast. Vamps like i – IV and i – VII. The basis of modal jazz, funk, folk and rock. Essence Minor without the Aeolian tragedy — more flexible and open-ended. It rests on that natural 6th.
