- Features a 16-bar extended blues structure, beginning with a static four-bar Bb7 opening that establishes a dominant-funk foundation.
- Incorporates a rapid ii-V-I-IV sequence in the relative major (Db), moving through Ebm7, Ab7, Dbmaj7, and Gbmaj7.
- Employs a standard minor ii-V-i turnaround (Cm7b5 – F7#9) to resolve the harmonic tension back to the Bb minor tonic.
Improvisation Focus
- Bb Minor Blues scale with Mixolydian modal switching.
Difficulty Rating
- 3/5: The non-standard 16-bar form and the transition into the relative major require more harmonic precision than a traditional jazz blues.
