Harmonic Highlights:
- The consistent minor ii-V-i progression (Em7b5-A7b9) anchors the D minor tonality.
- A poignant descending chromatic bass line (Dm, Dm/maj7/C#, Dm7/C) provides a signature melancholic sound.
- An extended sequence of secondary dominants (D9-G13-C9-F13) creates a rapid, cyclical modulation leading to Bbmaj7.
- Frequent use of altered dominants (A7b9, A7#5) injects rich chromatic tension and resolution.
Improvisation Focus: Altered Scale application over the numerous dominant 7th chords.
Difficulty Rating: 4 (Advanced). The rapid, cyclical modulations and frequent altered dominants demand sophisticated harmonic understanding.
