Harmonic Highlights:
- Frequent ii-V-I progressions (Am7-D7-Gmaj7) firmly establish the G major tonal center.
- Secondary dominant function is prominent, including G7 (V7/IV) leading to Cmaj7 and A7 (V7/V) preceding the dominant D7.
- Tonic harmony is enriched by alternating between G6 and Gmaj7, while D7sus-D7 resolutions add color.
- Sustained dominant chords (e.g., multiple D7s) build harmonic tension before tonic resolution.
Improvisation Focus: Targeting chord tones and Mixolydian modes over dominant 7ths.
Difficulty Rating: 3 (Intermediate). The clear ii-V-I structures are balanced by common secondary dominants requiring focused resolution.
