- Utilizes a ii-V-i (Am7b5–D7b13–Gm7) to tonicize the relative minor, creating the signature dark-to-light contrast typical of Shorter’s compositions.
- Employs secondary dominants (Fm7–Bb7) to modulate temporarily to the IV chord (Eb major), grounding the tune in a blues-influenced structure.
- Features chromatic dominant movement (A7#9 to Ab7) as a sophisticated turnaround to resolve back into the Gm7/Bb harmonic area.
- Incorporates a slash chord inversion (Bb7/F) to create a smooth, descending bass line leading toward the Em7b5.
Improvisation Focus Guide tone targeting (3rds and 7ths) to navigate the rapid shifts between Bb major and G minor tonal centers.
Difficulty Rating 3/5: The moderate tempo and functional ii-V progressions make it accessible, though the frequent modulation between relative keys requires keen harmonic awareness.
