Harmonic Highlights:
- The Ab07 chord functions as a rootless D7b9, acting as the V7b9 of Gm7 (ii minor), providing a colorful approach to the supertonic.
- Employs secondary diminished chords like F#07, which serves as the vii°7/ii (Gm7), creating strong chromatic resolution.
- Features both extended ii-V-I progressions in the tonic key (F) and a prominent ii-V-of-the-dominant sequence (Dm7-G7 leading to C7).
Improvisation Focus: Arpeggios and Guide Tone lines over frequent ii-V-I cycles and secondary harmonies.
Difficulty Rating: 4 (Advanced Intermediate). The blend of standard ii-V-I progressions with functional diminished substitutions and ii-V of the dominant demands a strong grasp of functional harmony and chromaticism.
