Harmonic Highlights
- The opening Em7b5-A7b9-Dm progression firmly establishes the D minor tonality with a characteristic minor ii-V-i movement and altered dominant.
- A significant secondary dominant, D7 (V7 of Gm), propels a modulation to F major via a Gm7-C7-Fmaj7 ii-V-I, temporarily shifting the key center.
- Frequent use of altered dominant seventh chords, like A7b9, provides strong voice leading tension and subsequent resolution into the minor tonic.
Improvisation Focus Navigating the constant interplay between D minor and its relative major (F major) tonalities.
Difficulty Rating 4 (Advanced Intermediate) - Requires proficiency with minor key harmony, altered dominant scales, and managing temporary modulations to the relative major.
