Harmonic Highlights
- Predominant use of minor ii-V-i progressions (Bm7b5-E7b13-Am7) firmly establishing the A minor tonality.
- Secondary dominant function is employed with A7b9 leading to Dm7, briefly tonicizing the subdominant.
- A significant shift to the relative major (Cmaj7) is achieved via a II7-V7 progression (D7-G7), providing harmonic contrast.
Improvisation Focus A Harmonic Minor scale and its related modes.
Difficulty Rating 3 (Intermediate). Navigating the minor key harmony, altered dominants, and a modulation to the relative major requires focused attention.
