Harmonic Highlights:
- The opening Cm7-Dbmaj7 progression establishes a distinctive Bb Phrygian or modal character, suspending functional resolution.
- A sudden chromatic shift from Ebm7 to Em7 introduces abrupt tonal instability, moving outside the initial Bb minor framework.
- The A7alt following Bbm7 presents a highly altered dominant, creating strong dissonance and implying tritone substitution.
- The Am7b5-Ab7-Gm7 sequence offers a characteristic descending minor progression, hinting at multi-tonic movement.
Improvisation Focus: Bb Phrygian Mode
Difficulty Rating: 5 (Advanced) – It demands acute awareness of sudden modulations, altered scales, and non-diatonic relationships, making navigation challenging.
