- Chromatic Bass Descent: The sequence Am – Abº7 – Gm7 – C7 utilizes a descending chromatic line (A-G#-G-Gb), where Abº7 acts as a rootless E7(b9)/G# leading into a secondary ii-V of the IV chord.
- Extended Diatonic Cycle: The progression Dm7 – G7 – Cmaj7 – Fmaj7 executes a full cycle of fifths, shifting the harmonic center momentarily to the relative major (C major).
- Neapolitan Substitution: The use of Bbmaj7 functions as a bII chord, providing a lush subdominant color that delays the resolution back to the Bm7b5 – E7b9 turnaround.
Improvisation Focus A Harmonic Minor (essential for navigating the E7b9 and providing the necessary G# leading tone).
Difficulty Rating 3/5: The piece requires intermediate skill to navigate rapid ii-V sequences and maintain melodic continuity through chromatic passing chords.
