Watch the Upward Movement online guitar lesson by Brad Carlton from Chord Studies: Pedal Tones Vol. 1
This is a vi-IV progression in the key of C; our chords are Am and F and we're keeping A in the bass. When moving from the A5 to the F/A, all you have to do is move up one position and come down with your third finger. For the Am, you're going to barre the first, second, and third strings with your fourth finger. Our last chord is a little different, an F chord using the D form out of the CAGED system. Notice how it looks like your standard D chord, just moved up.
