Watch the Gone With The Synth online guitar lesson by Brad Carlton from Chord Studies: CAGED Chords Vol. 2
This progression is a vi - IV - I - V progression in the key of F, and we'll be using forms out of the CAGED and EDCAG systems. The first chord is a Dm using the Dm form, and then we go to B♭ using the A form. Next up we have an F with an E form, and finish up strong with a C chord in C form. Let the chords sustain for a nice, clean keyboard synth type sound.
