Dominant Blues Rock Chord Progression on Guitar
The I7–IV7–I7–V7 form is a practical blues roadmap. In E, the chord sequence is E7, A7, E7 and B7. 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.
E 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.
