Harmonic Highlights:
- Features flexible ii-V-i progressions, alternating between F#m7 (Dorian) and F#m7b5 (Harmonic/Melodic Minor) leading to Em7.
- Includes a clear modulation to the relative major (Gmaj7) via a standard ii-V-I progression (Am7-D7-Gmaj7).
- Utilizes secondary dominant function, with a iiø-V progression (C#m7b5-F#7b9) targeting the dominant minor (B minor).
- Frequent use of altered dominants (B7b9, F#7b9, B7b13) adds tension and chromaticism throughout the progression.
Improvisation Focus: Mastering the various minor ii-V-i scale choices (Dorian, Harmonic Minor, Melodic Minor) and altered dominant scales over V7 chords.
Difficulty Rating: 4 (Advanced). The harmonic complexity, frequent alterations, and key center shifts require a sophisticated understanding of minor harmony and advanced scale applications.
