- The prolonged opening G7 functions as a blues-inflected dominant tonic, delaying clear functional harmony in G major.
- Chromatic mediant relation from E major to Ebmaj7 creates an abrupt, non-diatonic shift, showcasing sophisticated reharmonization.
- The tritone substitution Dmaj7 to Ab13b9 (Ab13b9 for D7) demonstrates advanced dominant chord manipulation within the home key’s V.
- F#7b13 immediately following Gmaj7 introduces a secondary dominant (V/B), hinting at modulations or extended dominant cycles.
Improvisation Focus: Navigating altered dominant scale applications across various key centers.
Difficulty Rating: 5 (Advanced). The rapid, unpredictable chromaticism and frequent use of altered dominants demand a high level of harmonic sophistication.
