Dorian vs natural minor
Dorian and natural minor share six of seven notes. The difference is the 6th: D Dorian has B, D minor has Bb. What that note does, and when to use each.
Six notes the same, one note different
D natural minor: D E F G A Bb C
D Dorian: D E F G A B C
The only difference is the sixth degree. Natural minor has a minor 6th (Bb); Dorian has a major 6th (B). Everything else — the minor 3rd, the perfect 5th, the flat 7th — is shared, which is why Dorian is heard as a kind of minor rather than as something separate.
What the major 6th does
In natural minor, the 6th sits a half step above the 5th and pulls down toward it — the dark, settled minor sound. In Dorian the 6th is a whole step above the 5th and does not pull down. It sits there brightly, and it turns the IV chord from minor into major: in D minor the iv is Gm; in D Dorian it is a plain G major. That i–IV move, Dm to G, is the signature Dorian vamp.
When to use which
- Use natural minor when the harmony is a minor key with a minor iv chord and a bVI — most rock ballads, most sad songs.
- Use Dorian when a minor chord sits next to a major IV: Santana, Pink Floyd, most funk and jam-band vamps, and any minor groove that feels lighter than it should.
- If you are not sure, play both over the chord and listen to the 6th. If the major 6th sounds right, it is Dorian.
