Harmonic Highlights

  • Employs a recurring i - II7 - V7 progression (Fm7 - G7 - C7) where the G7 provides a bright chromatic lift before resolving to the dominant.
  • Features a modulation to the relative major (Ab major) during the bridge using a series of ii - V7 - I cells.
  • Uses secondary dominants like F7b9 to tonicize the subdominant (Bbm7), creating strong internal resolutions within the minor key.
  • Incorporates a Bยฐ7 passing chord to facilitate smooth chromatic voice leading between the Bbm7 and Cm7 chords.

Improvisation Focus F Melodic Minor (and the G Lydian Dominant mode for the II7 chord).

Difficulty Rating 3/5: The song demands proficiency in navigating both minor-key cadences and quick modulations to the relative major.
