This Micro Lesson works through a "Soul R&B" style rhythm guitar riff in the key of "A Minor."
The riff starts out from the 5th position using a fifth-string root, "Dm7" chord, (the IV-chord from the key of "A" Minor). The initial attack upon this chord applies a hammer-on idea using the 3rd and 2nd fingers on the 4th and 2nd guitar strings. After these embellishments we find a Pentatonic Scale run going across the 4th through 2nd strings with embellishments using hammer-on, pull-off and slide concepts.
In measure two, the Tonal Center chord of "Am7" enters and uses another Pentatonic Scale line to connect it back into the "Dm7" IV-chord. The final measure after the repeat takes us into the turnaround phrase which uses an "Fmaj7" chord into an "Em7."
These are the "VI-chord and the "V-chord" of this key. The V-chord creates a popular sounding turnaround back into the top of the riff. Take your time if these chords are new for you. the fingerings can be somewhat challenging.
Use a metronome or drum machine to build the time and the feel. Enjoy!
