This Micro Lesson runs through a descending jazz-blues style chromatic lick across the strings from 1st all the way to 6th in the key of "A."
The lick begins on the 1st guitar string's tonic of the key (A) playing off of the minor 3rd and including a lowered 2nd degree.
The lick proceeds down into the second string performing the same geometrical pattern there. This generates a b7 (minor 7th) and a major 6th into a perfect 5th and an augmented 5th.
On the third string we have some classic blues based sounds with a minor and major 3rd into the 4th string root of "A."
Measure three uses a quick 16th-note triplet lick performed using a hammer-on and pull-off to take us into a dropping chromatic concept down the 5th string.
Resolution wraps things onto the tonal center of "A" at 6th string fifth fret. This lick will work great over an "A7" chord. Enjoy!
