12-Bar Blues (E)
Strumming: Shuffle triplet swing: long–short long–short
Focus: The 12-bar blues framework, I7–IV7–V7 dominant sevenths, and a shuffle swing groove
Transpose · Capo
The original key is inferred from the first chord in the chart. Transposing changes the chords you have to play; to keep easy shapes, switch to “Capo” instead.
💡 Too high to sing? Move down. Too low? Move up. Guys often go a few keys below the original, women a bit above — that's just a starting point. You've got it right when you can sing the highest line of the chorus comfortably.

Own it & make it yours
Goal: explain why it works and change up your own versionUnderstand why the harmony goes the way it does, then use the Transpose / Capo control above to change keys, and try reworking the rhythm, adding color chords or improvising — turn “I can play this one” into “I can play many.”

Structure
Chord function
Function: Tonic= the stable home · Subdominant= sets up the departure · Dominant= tension that wants to come home. Harmony is the story of leaving → tension → coming home.
Highlights
- ProgressionI7–IV7–V7: even the tonic is a dominant 7thI7IV7V7
The blues' most distinctive trait: even the “tonic” isn't a plain major triad but a dominant 7th (E7 / A7 / B7). That lingering minor-7th note creates the blues' signature “cry” and tension, soaking the whole tune in a lazy, unresolved mood.
Tip: Listen side by side with pop's I–IV–V (major triads) and the difference jumps out: the blues is “warmth with a hint of regret.”
- Rhythm / techniqueShuffle swing + a turnaround in the final bar
The blues needs a triplet “shuffle” swing feel (not straight eighths) to get that slow, easygoing flavor. The B7 in the last bar is the turnaround — instead of resolving home, it “sends you back to the top” to loop, leaving endless room for improvisation.
Tip: First get the 12 bars smooth with straight eighths, then slow to 60–70 BPM and add the shuffle — instant blues flavor.
