- Repeated i minor to IV dominant (Gm7-C7) establishes a bluesy, modal minor tonality.
- Chromatic dominant movement (C7-Db7) introduces tension and color through a half-step shift between dominant chords.
- Sophisticated V7/V to V7 to i progression (A7b9#5 -> D7#9 -> Gm7) utilizes highly altered dominant voicings.
- A concise modulation to Ab major via a standard ii-V-I progression (Bbm7-Eb7-Abmaj7) provides clear harmonic contrast.
Improvisation Focus: Adapting altered dominant scales across fluctuating key centers.
Difficulty Rating: 4/5. The numerous altered dominants and abrupt modulations demand advanced harmonic recognition and scale application.
