- Utilizes descending chromatic ii-V cells (Dbm7-Gb7 followed by Cm7-F7) that delay resolution to the tonic through constant tonal shifting.
- Employs B7b5 as a tritone-influenced dominant substitute to approach Bbmaj7, creating a smooth chromatic descent toward the A minor home key.
- Relies on repeated minor ii-V-i turnarounds (Bm7b5 - E7 - Am7) to provide structural stability amidst the high-frequency modulation of the bridge and transitions.
Improvisation Focus A Melodic Minor and the “Side-Slipping” concept for navigating chromatic ii-V sequences.
Difficulty Rating 4/5: The rapid succession of non-diatonic ii-V patterns and frequent modal shifts require advanced mental transposition and melodic fluency.
