Check out this two-bar bluesy rock lick based on the use of thirds and sixths intervals. As shown in the video, it works well as a fill-in to a rock riff!
Breaking it down
The lick is in A Dorian scale (A B C D E F# G). It starts with two nice sounding “minor thirds” intervals (E,G and F#,A in beat 1 to 3 of first bar) played back and forth. I like to highlight the beauty of the Dorian scale this way, which is the major sixth (F# in this case).
Then it moves up the neck playing a series of sixths along the scale (from beat 4 of first bar till the end) . Sixth is another cool interval that fits the blues rock context very well.
Rhythm-wise, the lick is based on 16th notes but in “group of three” arrangement . It is helpful to strictly follow alternate picking (down strokes on main beats， I.e. “1 and 2 and..”, up stroke on off beats I.e. “e” and “a”) to be rhythmic sound.
Gears: Quite a heavy distorted tone using AMT bulava pedal on an HnK amp!
