  • Prominent ii-V-I motion towards D major (Em7-A7-Dmaj7), the dominant of the overall G major key center.
  • Frequent use of iiø-V-i progressions, notably C#m7b5-F#7b9-Bm7, establishing the relative minor of D major.
  • Sequential minor iiø-V patterns (e.g., G#m7b5-C#7b9 followed by F#m7b5-B7b9) create rapid, transient modulations.
  • Extensive use of altered dominant chords (e.g., F#7b9, A7b9, G#7#5) to build tension and propel harmonic movement.

Improvisation Focus: Mastering melodic minor modes to navigate the frequent altered dominant and minor ii-V changes.

Difficulty Rating: 4 (Advanced Intermediate). The rapid, often sequential, ii-V and iiø-V progressions, coupled with numerous altered dominants, require sophisticated harmonic understanding and quick adaptation.
