Watch the Chordal Impracticalities online guitar lesson by Brad Carlton from Chord Studies: CAGED Chords Vol. 2
This progression is a vi - IV - I - V in the key of F. The progression starts with a Dm chord using the Em form in the tenth position. The B♭ stays in the same position, but switches to a C form. Then we have the F chord with a G form, which at first may seem impractical but it's important to learn these forms so that you can transpose these progressions easily. The final chord is the C chord with a D form. Here we are using the "V" shape with our second and third fingers to facilitate the somewhat ramped fingerings.
