Dorian Mode
Dorian is a minor mode with a major sixth. C Dorian contains A natural where C natural minor contains A flat. That degree changes the IV chord from minor to major and gives melodies a note that clearly separates Dorian from Aeolian.

How do you build Dorian?
Use the formula:
1-2-flat 3-4-5-6-flat 7
C Dorian is:
C-D-E flat-F-G-A-B flat-C
You can derive it by raising degree 6 of C natural minor or by using the notes of B-flat major with C as tonic.
Which note identifies Dorian?
The major sixth is the clearest comparison with natural minor.
In C Dorian, A natural forms a major sixth above C. It also forms the major third of F major, the IV chord.
Emphasize A over a C-minor drone or inside a Cm-F progression so it sounds related to C instead of B-flat major.
Which chords occur in Dorian?
Stack thirds from C Dorian:
- i: Cm
- ii: Dm
- flat III: E-flat major
- IV: F major
- v: Gm
- vi diminished: A diminished
- flat VII: B-flat major
The major IV is the most direct harmonic marker because it contains A natural.
How do you make C sound like the tonic?
Use a C drone or bass pedal and return to Cm at phrase endings.
A Cm-F vamp can establish C Dorian when C remains the center and A natural receives melodic emphasis.
If the progression cadences strongly to B-flat major, listeners may reinterpret the same notes as B-flat major. Tonal center comes from emphasis and harmonic motion.
How is Dorian different from Aeolian?
C Aeolian uses A flat and Fm. C Dorian uses A natural and F.
Both contain C, D, E flat, F, G and B flat. One degree changes.
Compare the melodic figure G-A-B flat-A-G against Cm, then lower A to A flat and repeat.
How is it different from melodic minor?
C melodic minor uses A natural and B natural. C Dorian uses A natural and B flat.
Both have a minor third and major sixth. The seventh determines whether the scale supports Cm7 or CmMaj7 and whether B leads directly to C.
Does Dorian require a two-chord vamp?
No. A vamp is simply an efficient way to keep the tonic clear.
Dorian melodies can appear over one minor chord, modal folk harmony or longer progressions. The harmony must preserve A natural and avoid repeatedly establishing another tonic.
One F-major chord does not prove a complete passage is Dorian; inspect the tonic and full pitch context.
Where is Dorian used?
Dorian appears in jazz, funk, soul, rock, folk and electronic music.
Jazz musicians use it over minor-seventh chords in appropriate contexts, especially ii chords. Modal pieces can treat the same minor chord as tonic.
Chord function matters: D Dorian over Dm7 in C major does not automatically make the whole piece D Dorian.
How should you practice it?
Hold C and alternate A flat with A natural.
Play Cm-Fm, then Cm-F. Identify which note changed and how it affects the fourth-degree chord.
Improvise over Cm-F using C, E flat, G and A as targets. End phrases on C so the mode keeps its tonic.
