- Frequent Tonicization of Relative Major: The recurring Fm7-Bb7-Ebmaj7 progression acts as a ii-V-I in Eb major, temporarily tonicizing the relative major of C minor.
- Characteristic Minor Cadence: The Dm7b5-G7b9#5-Cm7 progression provides a classic minor iiø-V-i cadence, with the G7b9#5 (featuring a #5 and b9) strongly leading to the minor tonic.
- Parallel Key Shift: A dramatic and sustained shift from Cm7 to Cmaj7 introduces the parallel major, creating a distinct harmonic contrast and requiring significant re-orientation.
- Sophisticated Voicings: Chords like Abmaj9 and Dm7b5/Ab suggest rich voicings and intentional bass line movement, adding harmonic depth beyond basic diatonicism.
Improvisation Focus: Navigating the shifts between C minor, Eb major, and C major tonalities.
Difficulty Rating: 4 (Advanced Intermediate). The frequent modal shifts, altered dominants, and parallel major changes require significant harmonic awareness and flexibility.
