25.40Jazz blues
Jazz often enriches the 12-bar blues substantially.
A common direction might include:
C7 | F7 | C7 | Gm7 C7 | F7 | F#°7 | C7/G A7 | Dm7 G7 | etc.
There are many versions.
The important point:
jazz blues keeps the 12-bar identity but adds ii–V, diminished, substitutions, and turnarounds.
