Harmonic Highlights:

  • The piece prominently features F7 as the tonic chord, immediately establishing a blues-dominant character rather than a pure major tonality.
  • A sophisticated secondary ii-V progression, Am7 D7b9, is used to briefly tonicize the Gm7 (ii) chord, adding a layer of harmonic movement.
  • The distinctive Ab7 (bIII7) chord appears, functioning as a chromatic passing dominant that “side-slips” into Gm7, creating a unique and colorful harmonic tension.

Improvisation Focus: Chord Tone Soloing, emphasizing accurate outline of specific chord qualities and their alterations.

Difficulty Rating: 3 (Intermediate) - The blend of bluesy tonic, secondary dominant cycles, and a striking chromatic chord requires a robust understanding of functional harmony and altered chord tones.
