Blues Turnaround Chord Progression on Guitar
The I7–VI7–ii7–V7 form is a practical blues roadmap. In C, the chord sequence is C7, A7, Dm7 and G7. Hear the dominant movement, keep the pulse steady and use the built-in transposition control to move the form to any guitar-friendly key.
Do this first
No theory test. No perfect technique required. Follow these three steps and start making music.
C major chords
Choose another key and the chord names update automatically. The Roman-numeral relationship stays the same.
Why this progression works
The repeating tonic, subdominant and dominant areas create expectation without losing the groove. Small changes in the final bars make the loop turn around naturally.
Practical shortcut
Do not rush the turnaround. Keep the final two bars as steady as the opening bars, because that is where most players lose the form.
Play it without stopping
Count four beats per chord and say the function before each change. Play only down-strums first, then add a shuffle or straight eighth-note feel after the form is secure.

Quick answers before you play
What do the Roman numerals in I7–VI7–ii7–V7 mean?
They describe chord positions inside a key. Uppercase numerals usually mean major chords and lowercase numerals usually mean minor chords.
Can I play this progression in another key?
Yes. Keep the same Roman-numeral pattern and choose a new key. The chord names change, but the musical relationship stays the same.
What strumming pattern should a beginner use?
Begin with one down-strum on beat one of every bar. Then use four down-strums before adding down-up movement.
