Harmonic Highlights:
- Establishes a minor blues tonality through the consistent use of G7 (tonic dominant) and C7 (subdominant dominant).
- Features a chromatic bVI7 (Eb7) resolving to V7 (D7), adding a distinct bluesy, non-functional color.
- Incorporates secondary dominants like A7 (V7/D) for tension, alongside temporary modulations to the relative major (Bb).
Improvisation Focus: G Minor Blues Scale.
Difficulty Rating: 4 (Advanced). The frequent dominant 7th chord changes, chromatic passing harmonies, and temporary modulations demand a strong command of jazz harmonic theory.
