This Micro Lesson applies the unique sounds of Modal Interchange off of a Tonic note of, "D."
The harmony of this progression operates between a, "Dmaj7," chord and a, "Dm7," chord. Each chord lasts two measures and functions within the Major and Minor harmonies.
In measure one, the, "Dmaj7," takes center stage with a quarter-note strum occurring at the first beat. A melodic statement carries the harmony into measure two where a pair of "6th Interval" double-stops help to both close out the, "D Major," harmony as well as, bring in the, "D Minor," harmony of the next phrase.
In measure three the, "Dm7," chord enters once again from the rhythmic feel of a strong quarter-note strum. The Minor tonality is highlighted through a similar melodic concept which we initially heard back in measure one. An eight-note line takes us out in measure four, yet still allows for this riff to operate as a repeated loop if the musician desires that effect.
Overall, this phrase can be performed by almost any guitarist who is at a reasonable level of skill. As always, memorize the part and then use a metronome or drum machine to help develop speed. Enjoy!
