- The progression utilizes a classic ii-V-I in Ab Major, frequently employing an Eb7#5 to increase tension and lead more strongly back to the tonic.
- A recurring I-iii-VI-ii-V cycle (Abmaj7-Cm7-F7-Bbm7-Eb7) defines the A section, necessitating smooth voice leading over the secondary dominant F7.
- The bridge initiates a temporary modulation to the subdominant (Dbmaj7) via a ii-V (Ebm7-Ab7), followed by an extended V/V (Bb7) that resets the primary key center.
Improvisation Focus Ab Major Bebop scale and Guide Tone targeting to navigate the secondary dominant resolutions.
Difficulty Rating 2/5: The structure is a predictable AABA form with standard diatonic movements, making it highly accessible for intermediate improvisers.
