12-bar blues in E
The most important form in American music. Three chords, twelve bars, infinite songs. E7 and A7 are two-finger shapes; B7 is the workout.
Why this progression matters
12-bar blues is the skeleton of blues, early rock and roll, and countless jam sessions. If you can feel twelve bars in E without getting lost, you can sit in with other musicians on a huge shared repertoire.
Practice note
Count bars out loud. Knowing where you are in the form matters more than strumming complexity.
Bottleneck change: A7 → B7
How to practice it
- 1Learn E7 and A7 first — both are quick two-finger shapes.
- 2Add B7 slowly; it's the four-finger challenge of this form.
- 3Count '1-2-3-4' each bar and say the bar number (1 through 12) as you play.
- 4Use all downstrokes or a simple shuffle; fancy patterns come after the form is memorized.
- 5Practice the last four bars (B7–A7–E7–B7) as a turnaround loop — that's where players get lost.
Where you'll hear it

FAQ
Do I need dominant 7ths, or can I use major chords?
Majors work in a pinch, but E7, A7, and B7 give the blues its pull. Learn the 7ths as soon as the form is clear — they're not much harder and sound right.
How do I stop getting lost in the twelve bars?
Count out loud and memorize the landmarks: four bars of I, two of IV, two of I, then the V–IV–I–V ending. Practice only bars 9–12 until the turnaround is automatic.
What strumming pattern fits a blues in E?
A simple shuffle (long-short eighths) or straight downstrokes on each beat. Groove and form matter more than pattern complexity at first.
