Harmonic Highlights:
- Standard ii-V-I progressions in F major and a tonicization of the subdominant (IV) key with Cm7-F7-Bbmaj7.
- Frequent use of altered dominant chords like D7b9 (V7/ii) and the colorful Eb7#11 (bVII7#11).
- Strategic employment of chromatic diminished 7th chords (Ab07, G#07) for passing motion and leading-tone functions.
Improvisation Focus: Altered Dominant Scales (e.g., Altered Scale, Diminished Scale, Lydian Dominant).
Difficulty Rating: 4 (Advanced Intermediate). The combination of standard changes with multiple altered dominants and chromatic diminished chords requires precise harmonic understanding and dexterity.
