Welcome to... "Micro-Lesson 146"
This Micro Lesson works through a lick in, "A Mixolydian," that can function well in a Jazz-Fusion situation.
Keeping in mind that, "A Mixolydian," is a mode of the "D Major," scale, we can think of this melodic idea as a lick which operates well over the Dominant 7th chord structure. Harmonies of "Dominant 7th" have major 3rd and minor 7th intervals alongside of perfect 5th's. These tones should not only be targeted in Jazz-Fusion, but also blended with minor 3rd intervals.
In this Micro Lesson's lick we begin from both major 3rd and root tones in measure one. Measure two adds the minor 7th "G" tone. And, measure three introduces the minor 3rd interval (C), against the major 3rd, (C#).
Practice the lick up to a point of memorization and then work on building it's speed. It's a fun lick that can work well over Mixolydian harmonies, or over any functioning or non-functioning Dominant 7th chord. Enjoy!
