- The A section replaces the standard I-VI-ii-V with a chromatic turnaround (Bb7 - Ab7 - Gb7 - F7), utilizing parallel dominant seventh chords that create a heavy, blues-inflected descent.
- It follows a modified Rhythm Changes structure, where the tonic Bb is treated as a dominant chord (Bb7) to facilitate the chromatic movement.
- The bridge employs a standard cycle of fourths (III7 - VI7 - II7 - V7) with #9 alterations, requiring precise navigation of secondary dominants and their resolutions.
Improvisation Focus Bb Blues scale integration over chromatic dominant cycles and Altered scales for the bridge.
Difficulty Rating 4/5; the non-diatonic chromaticism and the typically blistering bebop tempo require advanced technical facility and sophisticated harmonic targeting.
