Harmonic Highlights:
- Extended descending cycle of secondary iiø7-V7 chords (e.g., Em7b5-A7, Dm7b5-G7, C7-F7) creating a chain of dominant function leading to the home key’s dominant.
- Temporary tonicization of the subdominant via a ii-V-I progression (Fm7-Bb7-Ebmaj7), adding harmonic color and movement away from Bb.
- The F07 (F diminished 7th) functions as a chromatically altered dominant, providing a heightened sense of tension before resolution back to Bb.
Improvisation Focus: Navigating ii-V-I progressions with arpeggios and scales.
Difficulty Rating: 4 (Advanced Intermediate). Its rapid sequence of secondary dominants, frequent ii-V changes, and use of altered chords demand a strong grasp of jazz harmony.
