- Frequent tritone substitutions, notably Eb7#11 resolving to Dm7 and Ab7 following D7sus, create distinct harmonic tension and color within the D minor key center.
- Complex ii-V progressions, such as Bbm7-Eb7 and Em7-A7b5b9, utilize altered dominants and non-diatonic roots to expand the harmonic landscape.
- Chromatic chord movements, like Fmaj7 to F#m7 and Fm7-Bb7, introduce melodic interest and brief shifts to new implied tonal centers.
Improvisation Focus: Altered scales and chromatic approaches.
Difficulty Rating: 4 (Advanced) – Advanced due to frequent tritone substitutions, altered dominants, and rapid non-diatonic chord changes requiring quick adaptation.
