- Utilizes a foundational I-vi-ii-V cycle in Eb major, establishing a quintessential “rhythm changes” style functional base.
- Employs a secondary ii-V (Bbm7 - Eb7) to tonicize the IV chord (Abmaj7), creating a brief subdominant departure.
- Features a chromaticized ascending sequence (C7 - Fm7 - C7/G - Fm7/Ab - F7/A) that uses inversions and secondary dominants to drive linear tension toward the dominant Bb7.
Improvisation Focus Guide tone navigation through the secondary dominants to highlight the descending chromatic voice-leading of the 3rds and 7ths.
