Harmonic Highlights:
- Standard I-vi-ii-V and ii-V-I progressions form the harmonic backbone in F major.
- Dominant extensions like F7 (V7/IV) and bVII7 (Eb7) introduce chromaticism and backdoor dominant approaches.
- Temporary ii-V progressions (Am7 D7b13) target the Gm7 (ii) chord, while Fm7 Bb7 explicitly modulates to Eb.
- A complex sequence (G7b9, Cmaj7, Dm7b5, G7, Db7, C7) extensively tonicizes C, employing V-I resolutions, ii-V, and tritone substitution (Db7 for G7).
Improvisation Focus: Navigating temporary tonicizations and their associated altered dominant sounds.
Difficulty Rating: 5 (Advanced): The dense harmonic rhythm, frequent modulations, and use of altered dominants and tritone substitutions require sophisticated harmonic understanding.
