- The opening Am - Ab07 - Gm7 - C7 features a chromatic diminished chord (Ab07) leading into a ii-V of F major (bVI), providing early harmonic color and temporary tonicization.
- The harmony regularly employs classic ii-V-i progressions in A minor (Bm7b5-E7b9-Am) and resolves to the relative major (Dm7-G7-Cmaj7: ii-V-I in C).
- A significant harmonic detour involves a series of descending perfect fourths (Cmaj7-Fmaj7-Bbmaj7), briefly modulating to the bII major, adding a distant, lyrical quality.
Improvisation Focus: Mastering chord tone outlining and appropriate scale application across transient modulations.
Difficulty Rating: 4 (Advanced Intermediate) – Requires proficiency in navigating chromaticism, altered dominants, and rapid modulations to distant keys.
