Watch the Melodic Stroll online guitar lesson by Brad Carlton from Chord Studies: Jazz Turnarounds Vol. 1
This jazz turnaround is a I - vi - ii - V in the key of F, with the chords being Fmaj7 - Dm7 - Gm7 - C7. After the Fmaj7, your first finger will act as a guide finger as you move to the Dm7. Take note of the melody on the second string (E - F - F - E), as we always want our upper voices in these turnarounds to be melodic.
