Harmonic Highlights:
- Persistent interweaving of Fm9 and Fmaj9 establishes a distinctive minor/major tonal ambiguity over the F tonic.
- The sequence Bb13/F, Db7#11, C7b9 creates a complex pre-dominant tension, utilizing a tritone substitution (Db7#11 for G7) before the C7b9 resolves to F.
- The A7 functions as a V7/ii, expanding the harmonic progression beyond simple diatonic II-V-I movements within the F major section.
Improvisation Focus: Application of Melodic Minor modes for altered dominant and minor harmonies.
Difficulty Rating: 4 (Advanced). Requires familiarity with advanced dominant substitutions, modal interchange, and diverse scale applications.
