In this section I'll be superimposing an E Dorian scale over an E9 and an E13 chord.

The note that you'll want to be careful with using this approach is going to be the minor 3rd in the scale against the major 3rd in the chord. Typically what we do here when using pentatonic scales is to imply a blues bend up to the major 3rd from the minor 3rd.

The cool thing that happens when we add the extensions to the chord is that we get more chord tones or sweet notes to target and resolve to. Pull up the track and just walk through the scale as you play over the chords. Make a mental note of what sounds good to you and then try to target those tones when you take a solo.

We can also apply the E Dorian mode over an A13 chord. I'm thinking blues progression now and the A13 could be the IV7 chord in an E blues. You'll hear that the E Dorian works really nicely over this chord too. The reason is that when we study the E Dorian mode we find that it is derived from the D major scale. A13 would be the V7 chord in the key of D, so that's why the E Dorian works so well over that chord.

I hope all of this technical jargon makes sense to you. Take the time to analyze the chord scale relationships I've been showing you, it will strengthen your understanding of how these superimpositions work.
