Harmonic Highlights

  • Tonic prolongation via Gmaj7โ€“G6 movements maintains a stable, nostalgic atmosphere characteristic of mid-century balladry.
  • The G7#5 functions as a secondary dominant (V7/IV), utilizing chromatic alteration to pull strongly toward the subdominant (C major).
  • The A7 (II7) provides secondary dominant tension that typically resolves through the ii-V-I (Am7โ€“D7โ€“G) turnaround.
  • Standard diatonic cadences (IV-I and ii-V-I) reinforce a clear, unambiguous tonal center in G Major.

Improvisation Focus G Major Scale with a focus on targeting chord tones (3rds and 7ths) to navigate the secondary dominants.

Difficulty Rating 2/5. The progression is largely diatonic and follows predictable functional harmony, making it highly accessible for developing soloists.
