Harmonic Highlights:
- Establishes C minor strongly with repeated iim7b5-V7b9-im7 progressions.
- Utilizes the relative major (Ebmaj7) for a brief harmonic respite and color.
- Employs a clear secondary dominant (C7b9) to tonicize the iv chord (Fm7).
- The F#07 diminished chord functions as a chromatic passing tone or dominant substitute, increasing tension before resolution.
Improvisation Focus: C Harmonic Minor Scale.
Difficulty Rating: 3 (Intermediate). The combination of a consistent minor ii-V-i and common modulations makes it approachable but challenging enough for development.
