Dorian is the 2nd mode of major — minor scale with a
natural 6th (raised from aeolian's ♭6). C dorian:
C D E♭ F G A B♭ C. The natural 6 is the scale's
defining colour, distinguishing it from aeolian or phrygian.
Used over m7 chords in modal jazz (So What, Impressions,
Cantaloupe Island) and as the natural ii-chord scale in
any ii-V-I. The neutrality of the natural 6 makes it the default
m7 scale — no leading tones pulling toward a tonic, no sharp
dissonance with the chord underneath.
Now 2 octaves, both hands — the same pattern extended up and back with fingering marked above every note in each hand.
Intervals
1 – 2 – ♭3 – 4 – 5 – 6 – ♭7. Minor with natural 6.
