- The use of IV7 (Ab7) in the second measure introduces a bluesy, Lydian Dominant color that diverges from standard diatonic Eb major expectations.
- The progression features sophisticated “Circle of Fourths” movements, specifically the iii-VI-ii-V (Gm7-C7-Fm7-Bb7) turnaround, which drives the rhythmic momentum.
- Altered secondary dominants (C7b13, C7b9, D7b9) facilitate chromatic voice leading and create tension-release patterns common in bebop-era ballads.
- The Gm7b5-C7b9 sequence acts as a minor ii-V tonicizing the ii chord (Fm7), providing a brief excursion into darker, parallel minor tonalities.
Improvisation Focus Eb Major Bebop scale and targeted guide-tone (3rds and 7ths) connections to navigate the frequent ii-V-I turnarounds.
Difficulty Rating 2/5 — The harmonic rhythm is consistent and the piece remains largely anchored in Eb major, making it accessible for developing improvisers.
