- The progression opens with a minor ii-V-i in C minor (Dm7b5 - G7b9 - Cm7), utilizing a pedal point (Dm7b5/G) to create sophisticated harmonic tension typical of Evans.
- It employs rapid-fire secondary ii-V sequences (C7#9 to Fm7; Bb7 to Ebmaj7) that move through the circle of fifths, demanding quick mental modulation.
- The inclusion of Cmaj7#5 and Fmaj7#11 introduces Lydian Augmented and Lydian sonorities, shifting the texture from functional bebop to impressionist jazz.
- The Abmaj7 functions as a chromatic predominant or Neapolitan chord, providing a smooth voice-leading bridge back to the Dm7b5 turnaround.
Improvisation Focus C Melodic Minor, used strategically to navigate the minor ii-V-i sequences and provide altered tensions over dominant chords.
Difficulty Rating 4/5: The dense harmonic rhythm and constant shifts between major and minor modal centers require advanced technical facility and a deep understanding of chord-scale relationships.
