Harmonic Highlights:
- Frequent use of secondary dominants (D7-Gm7, A7-Dm7, F7-Bb) drives strong resolutions and propels harmonic motion within F major.
- Momentary tonicization of Bb major (F7-Bbmaj7) is established, followed by the borrowed bVIIm7-bIII7 (Bbm7-Eb7) progression, suggesting a backdoor dominant to F or temporary tonicization of Ab.
- The presence of B°7 (fully diminished) adds chromatic tension, often functioning as a substitute for a dominant 7th b9 chord (e.g., G7b9).
Improvisation Focus: Targeting chord tones and outlining the resolutions of secondary dominants.
Difficulty Rating: 4 (Advanced Intermediate) Requires agile navigation of numerous secondary dominants, momentary tonicizations, and borrowed chords that frequently shift harmonic centers.
