Harmonic Highlights:

  • Initial prolonged Abmaj7 functions as a non-diatonic, static harmony, establishing a characteristic “side-slipping” sound detached from immediate E minor functionality.
  • The Bm/maj7 to Cm/maj7 progression utilizes a striking chromatic shift of a minor-major 7th chord, a signature Shorter device for creating tension and forward motion without traditional diatonic resolution.
  • A clear C#m7b5 - F#7b9 ii-V-i progression targets the v chord (Bm) of E minor, offering moments of functional harmony amidst more ambiguous movements.

Improvisation Focus: Melodic Minor scale and its modes.

Difficulty Rating: 5 (Advanced) – The consistent use of non-diatonic harmony, altered dominants, and chromatic minor-major 7th movements requires a sophisticated understanding of modern jazz harmony.
