Harmonic Highlights:
- Dominant use of iiø7-V7b9-i progressions firmly establishes the A minor tonality.
- Alternates between the tonic minor (Am) and its relative major (Cmaj7) through ii-V-I movements.
- Features a secondary dominant (A7b9) temporarily targeting Dm7, expanding harmonic options within the relative major.
Improvisation Focus: A minor scale variants (natural, harmonic, melodic).
Difficulty Rating: 3 (Intermediate) - Navigating minor key harmony, relative major shifts, and secondary dominants requires focused attention.
