The Dorian mode works well when you hear it as a minor sound with a natural 6.
In D Dorian, the notes are:
D, E, F, G, A, B, C
A first Dorian line
The important color here is B natural. That is the note that separates Dorian from natural minor.
Over a small vamp
Try it on Dm7 - G7 - Dm7:
Ascending and descending
Use one ascending idea, then answer it with a descending one:
One practical routine
- Loop Dm7 or Dm7 - G7.
- Play one short ascending Dorian idea.
- Answer it with a descending idea.
- Make sure you hear B natural clearly.
Scale and arpeggio together
Do not play only scale runs. Mix scale and chord tones:
One thing to listen for
If the line sounds too close to plain minor, bring out the 6th more clearly. In D Dorian, that means giving more presence to B natural.
