- The progression centers on minor ii-V-i cells (Am7b5 – D7b9 – Gm7), utilizing the Harmonic Minor scale for strong dominant resolution.
- Sequential ii-V movements (Cm7–F7 to Bbm7–Eb7) briefly tonicize the relative major and its parallel minor, requiring quick shifts in tonal center.
- A descending line cliché (Gm7 – Gm7/F – Em7b5 – A7b9) creates a chromatic bass movement that sets up a secondary ii-V toward the dominant.
- The use of Eb7 as a predominant or tritone substitute leading to D7 provides a sophisticated chromatic approach to the final cadence.
Improvisation Focus G Melodic Minor, as it provides the necessary major 6th and 7th intervals for the tonic and supports altered extensions over the D7b9 chords.
Difficulty Rating 3 (Intermediate): The tune demands proficiency with minor-key harmony and the ability to navigate rapid modulations through several distant key centers.
