Harmonic Highlights

  • Utilizes a diatonic I-vi-ii-V progression in G major, establishing a stable, cyclic tonal foundation typical of swing-era structures.
  • Features a chromatic ascent from C to C#o7 to G/D, using the #ivo7 passing chord to bridge the IV chord to the tonic second inversion.
  • Employs a secondary dominant turnaround (E7 to Am7), functioning as a V/ii to drive the resolution back to the primary ii-V cadence.

Improvisation Focus G Major Pentatonic and the G Blues scale, emphasizing “sweet” major 3rds while navigating the #ivo7 passing tone.

Difficulty Rating 2 (Beginner-Intermediate) โ€” The slow harmonic rhythm and clear tonal center in G major make it highly accessible for developing improvisers.
