Harmonic Highlights:
- Features a characteristic chain of secondary dominant 7th chords (F7-Bb7-Eb7) creating transient modulations and pushing harmonic boundaries.
- Employs functional diminished chords, such as Ab07 preceding Gm7, for chromatic voice leading and added tension.
- Includes a significant modulation to the subdominant key (Bb major), highlighted by a prolonged Bbmaj7-Eb7 vamp section.
- Utilizes altered dominant voicings like C7b13 to add color and intensify the V7-I resolution in F major.
Improvisation Focus: Mixolydian mode, essential for navigating the numerous dominant 7th chords and their temporary resolutions.
Difficulty Rating: 4 (Advanced Intermediate) due to its frequent modulations, extended dominant cycles, and varied harmonic rhythm requiring precise melodic navigation.
