- Establishes a minor tonic (Dm6) despite the stated D major key center, hinting at dorian or aeolian influences.
- Features a descending dominant cycle (D7-G7-C7) leading to a temporary resolution in Fmaj7.
- Employs altered dominant chords (A7b9) and tritone substitution (Bb7 before A7) to create tension and resolution.
- Frequent use of minor ii-V-I progressions (Em7b5-A7b9-Dm) reinforces the minor tonality throughout sections.
Improvisation Focus: Mastery of D Dorian/Natural Minor scales and applying altered scales over the various dominant functions.
Difficulty Rating: 4 (Advanced Intermediate) Its shifting tonal centers, frequent altered dominants, and reliance on minor ii-V-I progressions require precise harmonic understanding.
