Watch the Home Base online guitar lesson by Brad Carlton from Chord Studies: Double-Stops Vol. 1
This example mirrors Example 4 where we were descending down the A Mixolydian mode in thirds. Notice how in this example we have three different chords, A6, A7, and our stock A, which would all work as a tonal home base. Try experimenting with all three of these as the starting chord to mix things up. Also, the first two chords give us a great place to work in some chromaticism. Chromaticism is when you use half steps to link notes from the scale together. One way to do this is to hit the A6 chord, move the shape down a half step (so 13th fret on both the E and G string) and then land on the A7 chord as normal. Rhythmically you could cut the length of the A6 chord in half, move to the chromatic shape on the 13th fret, and then land on the A7 chord when you normally would.
