- The opening ii-V (Em7b5 to A7b9) targets D minor, the v-minor, creating immediate tonal ambiguity by avoiding the G minor tonic.
- Employs descending ii-V sequences (Cm7-F7 followed by Fm7-Bb7) that cycle through transient tonal centers including Bb and Eb.
- Features a “backdoor” dominant (Ab7) resolving from IV (Ebmaj7) toward the Bb/Gm tonic area, showcasing non-functional chromatic movement.
- Incorporates subdominant minor movements (Bbm7 to Eb7) to pivot toward F major, momentarily shifting the modal center before returning to minor-inflected cadences.
Improvisation Focus Voice leading through shifting ii-V-I cells.
Difficulty Rating 4/5 - The constant modulation and non-diatonic starting point require advanced harmonic fluency and melodic flexibility to navigate the rapidly changing key centers.
