Harmonic Highlights
- Strong tonicization of F major (IV) via Gm7-C7-Fmaj7 and D minor (ii) through Em7b5-A7-Dm7 progressions.
- Prominent use of secondary dominants, exemplified by A7 to Dm7, and D7 to Gm7, creating temporary shifts in tonal center.
- The overall harmonic rhythm features clear ii-V-I resolutions back to C major, anchoring the piece despite the modulations.
Improvisation Focus Navigating ii-V-I cycles and temporary key centers.
Difficulty Rating 3 (Intermediate) - The frequent shifts to related keys and secondary dominants require a solid understanding of functional harmony and effective scale/arpeggio transitions.
