Harmonic Highlights

  • Features a delayed tonic resolution using a recurring ii-iii-VI-ii-V sequence (Am7-Bm7-E7-Am7-D7) to sustain harmonic tension.
  • Utilizes a C7 chord as a bluesy dominant IV, creating a momentary modal shift that deviates from strictly diatonic G major.
  • Incorporates a minor ii-V-i turnaround (F#m7b5-B7-Em7) to pivot the harmony toward the relative minor (E minor) key center.

Improvisation Focus G Major Bebop scale with specific emphasis on targeting the 3rds and 7ths of the secondary dominants (E7 and B7).

Difficulty Rating 3/5 โ€” The progression is grounded in G major but requires fluid navigation of secondary dominants and minor-key turnarounds.
