Harmonic Highlights:
- Prominent use of bVIImaj7 (Bbmaj7) in C minor, often followed by F7 (V7/Bb), introducing a dorian or Mixolydian flavor.
- A clear modulation to the relative major (Eb major) via a ii-V-I-IV progression (Fm7-Bb7-Eb7-Ab7).
- Extended dominant preparation (D7-G7) prior to the Cm tonic creates significant tension and resolution.
- The C7 chord functions as a secondary dominant (V7/F), leading into a chain of dominants and adding a strong bluesy drive.
Improvisation Focus: Dominant 7th scale applications and alterations.
Difficulty Rating: 5 (Advanced) due to frequent modulations, non-diatonic chords, and extended dominant cycles requiring sophisticated harmonic navigation.
