Harmonic Highlights:
- Frequent ii-V-I progressions (
Am7-D7-Gmaj7,Dm7-G7-Cmaj7) strongly define G major and C major tonal centers. - The
C7#11functions as a Lydian dominant, typically resolving to F major (implied). - Rapid modulations between these established key centers are a core harmonic feature, demanding quick harmonic reorientation.
Improvisation Focus: Fluid navigation of ii-V-I progressions, using appropriate major scales and their related arpeggios.
Difficulty Rating: 3 (Intermediate). The frequent modulations require keen awareness of shifting tonal centers and corresponding scale choices.
