Harmonic Highlights:

  • Utilizes a “falling” bass motif through stepwise inversions (D7/F#, Ebmaj7/G, C7/E), creating a smooth chromatic descent that defines the tune’s title.
  • Features rapid tonal shifts via ii-V sequences that cycle through G minor, Eb major, and G major, requiring quick harmonic pivots.
  • Employs deceptive resolutions and chromatic root movements, such as Fmaj7 to F#m7b5, to transition into unexpected key centers like E minor.

Improvisation Focus: Voice-led guide tone connection across shifting key centers.

Difficulty Rating: 4/5: The dense harmonic rhythm and frequent, non-standard modulations require advanced navigational skills and precise linear phrasing.
