Harmonic Highlights:
- Clear ii-V-I progressions (Gm7-C7-F) establish the F major key center.
- Frequent non-diatonic dominant 7ths (Eb7, D7, Gb7, Db7) indicate extensive secondary dominant and tritone substitution usage.
- The recurring
Eb7-D7oscillation creates distinctive harmonic tension and chromatic voice leading. - Diminished chords like F#07 function as chromatic passing tones, enriching the harmonic vocabulary.
Improvisation Focus: Altered Scale.
Difficulty Rating: 4 (Advanced Intermediate). Its complexity stems from frequent chromaticism, diverse dominant functions, and implied temporary modulations.
