This Micro Lesson runs through a Classic Rock riff in the key of "A Minor."
The riff applies harmonic movements based out of the "A Dorian" scale.Two chords are used to push a melodic line that ties them together.
The "A Minor" chord is the tonal center chord, while the 'lead in' chord of, "D Major," acts as a 'IV major' chord.
All melodic concepts for the riff, (found in measures 2 and 4), are built out of the "A Minor Pentatonic Scale."
A passing tone from the, "A Blues Scale," (the diminished 5th of Eb), is applied in measure four to spice up the turnaround structure of the final single-note line. Enjoy!
