Harmonic Highlights:
- Frequent minor 6th chords (Am6, Dm6) establish a modal minor quality, often functioning as i and iv.
- A clear ii-V-i progression (Bm7b5-E7b9-Am6) consistently grounds sections in A minor.
- Temporary modulation to C major via a G7-Cmaj7 progression introduces new tonal centers.
- A dominant chain (B7-E7) builds tension, creating a strong pull towards the primary A tonality.
Improvisation Focus: Applying chord-scale relationships accurately across local key changes.
Difficulty Rating: 4 (Advanced Intermediate). It demands precise navigation of minor modes, altered dominants, and multiple temporary modulations.
