Harmonic Highlights

  • Rapid Tonicization: The sequence utilizes constant shifts between the home key of E major and parallel minor areas (Em, Am), creating a fluid, impressionistic tonal center.
  • Chromatic Passing Tones: The use of Gยฐ7 acts as a symmetrical connector between the II7 (F#7) and the iii (G#m7), smoothing a non-diatonic transition.
  • Sequential ii-Vs: Shifting patterns such as Fm7-Bb7 represent abrupt modulations to distant flat-side keys, necessitating precise voice-leading across unrelated harmony.

Improvisation Focus Constant Modal Modulation: Prioritize targeting 3rds and 7ths to navigate the rapidly changing tonal centers rather than relying on a single parent scale.

Difficulty Rating 4 (Advanced): The frequency of non-diatonic shifts and unconventional resolutions requires sophisticated melodic ear-to-chord connection and quick harmonic reflexes.
