Harmonic Highlights:
- Features pervasive minor ii-V-i progressions, notably
Em7b5-A7b9-Dm7leading to D minor. - Employs altered dominants (
D7b13) and modal interchange chords likeEb7#11(bVI7#11), functioning as a Lydian Dominant. - Exhibits temporary tonicization, as seen in the
Gm7-C7-Fmaj7sequence, implying a brief shift to F major.
Improvisation Focus: Melodic Minor Scale and its derived modes (e.g., Altered Scale, Lydian Dominant).
Difficulty Rating: 4 (Advanced Intermediate). Navigating minor ii-V-i progressions, altered dominants, and temporary modulations requires a strong grasp of specific scales and harmonic functions.
