Dorian mode

1 - 2 - ♭3 - 4 - 5 - 6 - ♭7

Dorian is one of music’s most common and versatile modes.

It’s minor-sounding, and the most common way it's described is "a minor scale with a ♮6" - that is, one degree brighter - but compared to the minor scale (Aeolian), it lacks the dramatic gravity. Instead, Dorian is more content to circle and groove, and marinate in a smaller harmonic space. It's the backdrop for long night drives, urban landscapes, and sea shanties.

It's about as common as Aeolian too, in practice. Which is to say, very, very common.

And it’s also a Mixolydian scale with a flat 3rd. Whereas Mixolydian is the harmonic engine of classic rock, Dorian is the chill groovy scale on the dark side of the line.

Where do you see Dorian used?

A ton of places. Folk, rock, funk, jazz, 80s pop, soul, trance, you name it.

You don’t see it as often in really dark places like death metal, you don’t see it used much in classical music (Mozart etc.), and you don’t see music sticking to just Dorian when it wants an uncommon harmonic sound.

Why does it work so well?

• The root chord, the i7, is gold
  • Every note in the scale sounds strong played over the i7: it’s got a 9th, an 11th, and a 13th. This also means you can use those chord extensions to play different variants of the i7 chord in your harmony instrument (guitar, piano, etc.)
• The natural 6th is a great color, and gives you some great chords.
  • For example: where Aeolean has the dark and powerful iv7 and ♭VI chords, Dorian has a the cool IV7 and vi7♭5 chords.
• It's built for vamping: without Aeolian's strong subdominant and dominant functions (the harmonic moves that give you strong turnarounds), Dorian excels at circular grooves more than directional progressions. It’s better at atmosphere than stories.
  • Dorian excels at two-chord vamps, though there are a lot of great 3- or 4-chord vamps. Dorian can and does support longer chord progressions sometimes, they’re just not anywhere near as strong or clear feeling as Aeolian’s progressions.

How is the mode structured?

I think the best way to understand Dorian is to understand its simplest 2-chord vamps first. The most characteristic Dorian vamps emphasize the ♮6 (natural 6th).

You have two A-side vamps and two B-side vamps:

The i7 - IV7 pair: A-side: i7 - IV7 (the classic funk vamp, unbelievably common) B-side: i7 - vi7♭5 (same underlying motion, but a more “lifted” color)

The i7 - ii7 pair: A-side: i7 - ii7 (melancholy, floating) B-side: i7 - ♭VII7 (bright, moving)

It also has the i7-v7 vamp and the i7-♭IIImaj7 vamp, but those both serve more specialized roles.
