Pentatonic Minor Derived from Dorian Mode (November 2011)

Pentatonic minor or Blues Scale is located within the Dorian mode.

Those who have theory knowledge would have seen this rarely discribed because the pentatonic minor blues scale is generally taught as an independant scale based on a mode of the major pentatonic scale. The pentatonic scale is created from the major scale.

The degrees for the Dorian mode, relative to (made up from notes of ) the C major scale: D E F G A B C D, 2 3 4 5 6 7 1 2

Pentatonic minor: D F G A C D, 2 4 5 6 1 2

This method discribes the use of the blues riff 2 6 2 7 2 1 2 7

By using the Dorian mode to obtain the Pentatonic minor scale rather than deriving the scale from the major Pentatonic scale, you can now
discribe the origin of the 1 in the previously mentioned blues riff.

This may all sound a bit busy to a student. By learning the Guitarmodes
method, this information will be easily comprehended.
