Watch the Mix It Up online guitar lesson by Brad Carlton from Chord Studies: Inversions Vol. 1

This example is a little different from the last six.  Now we're looking at a four bar progression involving two different chords.  We will play through the two chords using two different string groups: the first and second measure are played on the first, second, and third strings, while measures three and four are played on the second, third, and fourth strings.  Keep an eye out for places where you can keep your fingers on the same strings as you change from chord to chord, a concept called "guide fingers".
