- Establishes A minor as a tonic, frequently returning via strong minor ii-V-i progressions (Bm7-E7b9-Am9).
- Features a chromatic backdoor dominant sequence (Eb7-Ab7sus-Dbmaj7) leading to temporary major resolutions.
- Employs descending major seventh chords by half-step (Dbmaj7-Cmaj7), adding rich chromatic voice leading.
- Utilizes modal interchange, such as Fmaj7#11 (bVI Lydian), creating distinct color before dominant preparation.
Improvisation Focus: Navigating A minor tonality, including harmonic minor, and related altered dominant scales.
Difficulty Rating: 4 (Advanced Intermediate) - The frequent modulations, chromaticism, and use of altered dominants require a solid understanding of advanced harmony.
