Harmonic Highlights:
- Strong tonicization of the relative major, C major, through recurring Dm7-G7-Cmaj7 ii-V-I progressions, creating a major-key feel within the A minor context.
- Frequent secondary dominant usage, particularly A7 (V7 of D minor), establishes D minor as a prominent temporary tonal center.
- Minor ii-V-i progressions (e.g., Em7-A7b9-Dm7) are used effectively, reinforcing minor tonalities and adding harmonic tension.
- The harmony demonstrates a fluid oscillation between the stated A minor key center and its relative major, C major, enriching the melodic and improvisational possibilities.
Improvisation Focus: Navigating the interplay between C Major and A minor modes and their respective ii-V changes.
Difficulty Rating: 3 (Intermediate). The rapid succession of ii-V-I progressions and temporary modulations requires a solid understanding of chord-scale relationships.
