Minor blues
i7 (4 bars) – iv7 (2 bars) – i7 (2 bars) – VI7 – V7 – i7 – V7The 12-bar form in a minor key, with ♭VI7 leading to the dominant V7.
In Am: Am7 – Dm7 – Am7 – F7 – E7 – Am7 – E7

Why they work
Bars 1–4 stay on I, bars 5–6 move to IV, bars 7–8 return to I, and bars 9–12 are the turnaround: V, IV, I and V again to lead back to the top.
The quick change visits IV in bar 2; jazz blues adds a ii–V in bars 9–10; minor blues swaps in minor i and iv chords and a ♭VI7 before the V7.
