Harmonic Highlights

  • Relies on standard ii-V-I cycles in G major (Am7 - D7 - G6), establishing a firm tonal foundation and clear cadences.
  • Incorporates a secondary dominant G7 (V7/IV) to tonicize the IV chord (Cmaj7), a hallmark of swing-era songcraft.
  • Employs A7 (V7/V) as an extended dominant to create chromatic tension before resolving to the dominant D7.

Improvisation Focus G Major Bebop Scale (integrating a D# passing tone) to maintain chord-tone alignment over diatonic changes.

Difficulty Rating 1/5: The predictable diatonic structure and slow harmonic rhythm make it an ideal introductory piece for jazz students.
