Harmonic Highlights

  • Features a classic minor line clichĂ© (Cm–Cm/maj7–Cm7–Cm6), creating chromatic inner-voice movement over the tonic minor.
  • Utilizes F#o7 as a chromatic passing chord between the iv (Fm7) and the Gm7b5, facilitating a smooth transition through the subdominant area.
  • Employs secondary minor ii-V progressions (Gm7b5–C7b9) targeting the iv chord, showcasing Porter’s signature minor-key sophistication.
  • Integrates Ebo7 to F7 movements, leveraging diminished-to-dominant chromaticism to create tension and harmonic momentum before resolving.

Improvisation Focus C Melodic Minor and its modes (specifically Locrian #2 and Altered) to navigate the frequent minor ii-V-I patterns and line clichés.

Difficulty Rating 3/5. The sophisticated chromaticism and typically “up” tempo require solid control of minor-key voice leading and precise rhythmic execution.
