Harmonic Highlights

  • Employs standard I-vi-ii-V cycles (Gmaj7โ€“Em7โ€“Am7โ€“D7) which establish a firm diatonic foundation in G Major.
  • Features iii-VI7-ii-V7 turnarounds (Bm7โ€“E7โ€“Am7โ€“D7) to introduce secondary dominant tension and smoother voice leading.
  • Utilizes modal interchange via the minor ii-V (Am7b5โ€“D7b9), providing subdominant minor color before returning to the tonic.
  • Altered dominants like B7#5 and E7b9 create strong resolution points through chromatic alterations of the 5th and 9th.

Improvisation Focus G Major Bebop scale with an emphasis on chord-tone targeting (3rds and 7ths) during secondary dominant resolutions.

Difficulty Rating 2/5; the progression is largely cyclical and adheres to standard jazz vocabulary, making it highly approachable for intermediate students.
