Continuing to tap arpeggio sequences Workout #3 steps it up a notch with 16th notes, an open string and varying patterns. At 50bpm you'll have a slow enough tempo to adapt to the 16th note feel as well as work your way around the added open string. In regards to the latter the open string serves as a static element in the chord progressions I've composed on each of the six strings. For instance, on the hi-E string in the first bar the open E is the 5th of the A and Am chords whereas in the second bar it's the root of the Em and E chords. Another classic VH approach - think "Hot For Teacher" or "Spanish Fly."
