- The progression utilizes a recurring i - viø7 - iiø7 - V7 movement, where the Em7b5 (viø7) provides a Dorian-inflected lift before the standard minor turnaround.
- The Eb7#11 serves as a dominant-functioning bVI chord, acting as a tritone substitute for the secondary dominant (A7) to lead chromatically into the D7b9.
- Chromatic diminished passing chords such as E°7 and Bb°7 facilitate smooth voice leading and create tension between established tonal centers.
Improvisation Focus: G Melodic Minor.
Difficulty Rating: 3/5. The fast harmonic rhythm and the necessity of navigating minor ii-V-i turnarounds at typically brisk tempos demand precise linear phrasing.
