Harmonic Highlights
- Utilizes a 12-bar blues form in F major, heavily infused with bebop harmonic substitutions.
- Features dominant 7th quality for both the tonic (F7) and subdominant (Bb7) chords throughout the progression.
- Incorporates a chromatic passing diminished chord (Bø7) between Bb7 and F7, creating tension before resolving to the tonic.
- Employs sophisticated ii-V progressions and secondary dominants (e.g., Am7-D7 as ii-V to Gm7, and Gm7-C7 as ii-V to F) to enrich the blues turnaround.
Improvisation Focus Bebop scales and arpeggios for outlining complex chord changes.
Difficulty Rating 5 (Advanced) - Requires precise navigation of rapid harmonic rhythm, frequent ii-V substitutions, and chromatic passing chords.
