Harmonic Highlights:
- Frequent tonicization of the relative major (Ebmaj7) via ii-V progressions (e.g., Fm7-Bb7-Ebmaj7), creating a fluid major/minor interplay.
- Classic minor key iiø-V7-i resolutions (Dm7b5-G7b9-Cm6), often preceded by chromatic descents, firmly establishing the C minor tonality.
- Use of secondary dominant C7b9 to emphasize the subdominant minor (Fm7), adding a characteristic minor key color.
- Strategic placement of a diminished chord like Gb07 (e.g., Gm7-Gb07-Fm7) for chromatic voice leading and tension.
Improvisation Focus: C Melodic Minor (and its modes).
Difficulty Rating: 4 (Advanced Intermediate) – Requires navigating frequent modulations to the relative major and intricate minor key harmonies with chromatic embellishments.
