Harmonic Highlights:
- Begins with extended tonicization of C major (relative major) via ii-V-I progressions (e.g., Dm7b5-G7b9-Cmaj7), delaying the primary A minor key center.
- Features descending ii-V-I modulations, notably to F major (bVI of A minor) before establishing the Am tonic (Bm7b5-E7-Am).
- Utilizes characteristic minor iiø-V progressions for both the tonic and secondary keys, like Em7b5-A7b9 (iiø-V of D minor).
- The
Bm7-E7beforeAmsuggests parallel major borrowing, adding a dorian-like color to the dominant approach.
Improvisation Focus: A Harmonic Minor scale and its derived modes (e.g., Phrygian Dominant for V7 chords), adaptable for diverse ii-V resolutions across shifting tonal centers.
Difficulty Rating: 4 (Advanced Intermediate) Frequent modulations and sophisticated minor-key harmony, including altered dominants, demand a strong grasp of functional harmony and modal applications.
