Watch the Major Triad Inversions on Low Strings online guitar lesson by Robben Ford from Chord Revolution: Foundations

Let's just take those first two chord voicings. Takes you very nicely to the key of A. That chord voicing is serving a function. It's taking you some place. The bass note is moving up, and it leads you, beautifully to that A triad. You could do that. This is a perfect way to move around the guitar. You are your own bass player, basically. Particularly that E to A thing should serve you pretty well. We've also included all of the other chord inversions in chart form with all the string groups. You'll be able to see all these triads played in myriad different ways all over the fingerboard.
