Harmonic Highlights:
- Features a prominent i-bVI7-V7-i progression (Cm7-Ab7-G7-Cm7), establishing a characteristic minor jazz sound.
- Incorporates a series of dominant 7th chords like C7-F7-Bb7, creating temporary tonicizations and hinting at blues harmonic language.
- The C7 (I7) functions as a secondary dominant (V7/F) or a blues tonic, leading into a functional dominant cycle.
Improvisation Focus: C Harmonic Minor scale, particularly over the Cm7 and G7 chords, to emphasize the minor tonality and leading tone.
Difficulty Rating: 4 (Upper Intermediate). The blend of minor key harmony with non-diatonic dominant chains and substitutions requires precise harmonic understanding.
