- The progression utilizes Neapolitan shifts (Ebmaj7) and chromatic planing (Abmaj7), deviating from standard functional minor harmony to create a “cool” modal atmosphere.
- A deceptive transition from Abmaj7 to Am7-D7 moves the tonality from a static modal texture into a functional ii-V leading to Gm7.
- The structure features a contrast between chromatic A sections and a traditional ii-V-I turnaround in the relative major (F major) during the bridge.
Improvisation Focus D Melodic Minor shifting to Eb Lydian to navigate the prominent non-diatonic major chords and chromatic substitutions.
Difficulty Rating 4; the frequent non-diatonic modulations and “side-slipping” major seventh chords require sophisticated modal interchange skills and precise linear targeting.
