Watch the Dorian online guitar lesson by Chris Buono from Modes That Matter
Perusing the Dorian formula--1 2 b3 4 5 6 b7--you can see with its flatted 3rd degree itís of the minor ilk. Additionally there's a b7 allowing Dorian to produce the ever-important min7 chord, which is featured in the upcoming Minor Blues segment (see the accompanying Power Tab chart). However, the color lies within the tritone interval (b5) between the b3rd and the 6th degree. This can be heard big time in the m6 and m6/9 chords that are played in this segmentís jam track. As you watch and listen not just to Dorian, but all the scales and modes throughout this course, be sure to key in on where the tritone is located. More often than not it is that interval that defines a scale or modeís overall sound.
In addition to playing Dorian over various minor chord forms that are diatonic to its formula, this scale is often superimposed over other chords to emphasize that chord's color tones and tensions.
