Harmonic Highlights

  • Frequent cycling between Eb Major and C Minor tonalities via standard ii-V-I progressions (Fm7-Bb7-Ebmaj7 and Dm7b5-G7b9-Cm6).
  • Chromatic voice leading through the Gbยฐ7 passing chord, bridging the gap between the iii (Gm7) and the ii (Fm7).
  • Tonicization of the subdominant via the C7b9 (V/ii) secondary dominant resolving to Fm7.
  • Strong minor-key resolution using Cm6, emphasizing the natural 6th for a sophisticated melodic minor character.

Improvisation Focus Navigating the tonal shift between the Eb Major scale and the C Harmonic/Melodic Minor scales.

Difficulty Rating 3/5. The tune requires precise navigation of parallel major/minor functional shifts and accurate phrasing over chromatic diminished passing chords.
