Harmonic Highlights:
- Frequent iiø-V7b9-i progressions (
Em7b5-A7b9-Dm) firmly establish the D minor key center. - Prominent descending bass lines, such as
Dm - Dm/C - G/B, provide smooth voice leading and harmonic depth. - Temporary modulations occur via secondary dominant cycles (
Am7-D7-Gm7-C7) and backdoor progressions (Bbm7-Eb7), expanding the harmonic landscape beyond simple minor.
Improvisation Focus: Navigating temporary tonal centers.
Difficulty Rating: 4 (Advanced Intermediate). The frequent modulations, secondary dominants, and blues-infused altered chords demand sophisticated harmonic awareness and fluid scale transitions.
