As with so much in music theory, if I give you an absolute answer there will be exceptions.dusted william wrote:Thanks Nuffink,
Let me see if I understand what you're saying.
I only know basic stuff about theory, this is way over my head.
If I want to play in Dorian I can only really play one chord?
Thanks,

Basically yes, in a specific major key only one chord will give Dorian tonality. It's the minor chord based upon the second degree of the major scale. But...
You can extend that chord to a minor seventh. You can add any combination of the 9th, 11th or 13th as a tension. You can substitute the sus4 or sus2 based on the second degree and their extended forms. You can play fast and loose with voicings (the minor seventh in first inversion is a 6th etc).
You can also modulate. Miles Davis' "So What" has 16 bars of Dmin7 (D Dorian) followed by 8 bars of Ebmin7 (Eb Dorian) followed by a return for 8 bars of Dmin7.
And I'm sure that's a far from complete list of tricks musicians have use to enliven static harmony.
