Harmonic Highlights
- Features prominent borrowed harmony with the Cm7-F7 (ivm7-bVII7) progression, introducing a minor color into the G major key center.
- Frequent use of descending ii-V progressions and their extensions (e.g., Bm7-E7-Am7-D7), providing a strong sense of forward motion.
- Strategic deployment of secondary dominants and altered chords (e.g., C#m7b5-F#7b9) to create temporary tonicizations within the diatonic framework.
Improvisation Focus Navigating rapid chord changes using bebop scales and precise chord tone outlining.
Difficulty Rating 4. The consistent stream of ii-V-I progressions, altered dominants, and borrowed chords requires significant harmonic agility.
