This Micro Lesson covers a double-stop riff in the key of "A."
The riff begins with ascending and descending slides on the upper strings covering the harmony of an "A Major" chord.
In measure two, we have more double-stops covering the harmony of an "E and D" major chord. Measure three changes things up slightly by applying an arpeggiated idea covering the harmony of an "A Major," chord.
Measure four breaks down further use of the double-stops by pushing in a "G" Major chord. The riff is a relatively easy one that doesn't require fast playing or highly developed technique.
Take your time building the phrasing and the fingering. One strong recommendation is to use the ring finger of the fret-board hand to play the initial slide in measure one. Most of all have fun and work to develop your timing so the riff is smooth. Enjoy!
