Harmonic Highlights
- Pervasive use of the minor ii-V-i progression (Em7b5 - A7b9 - Dm) defines the D minor tonality.
- Strong tonicization of the relative major (Fmaj7) through its ii-V (Gm7 - C7), providing a contrasting major key resolution.
- The D minor tonic is often articulated with Dm7 and Dm6, suggesting a D Dorian or natural minor framework over sustained minor chords.
Improvisation Focus Navigating minor ii-V-i progressions.
Difficulty Rating 3 (Intermediate). Requires proficiency in minor key harmony and adapting scales for V7b9 chords and relative major modulations.
