Harmonic Highlights:
- The piece prominently features
F7as 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 theGm7(ii) chord, adding a layer of harmonic movement. - The distinctive
Ab7(bIII7) chord appears, functioning as a chromatic passing dominant that “side-slips” intoGm7, 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.
