Harmonic Highlights

  • Employs a cyclical ii-V-I structure in G major, providing a highly functional and stable tonal foundation.
  • Features a brief “side-stepping” modulation in the second half, shifting from a ii-V in C major (Dm7-G7) to a ii-V in Bb major (Cm7-F7).
  • Utilizes a slow harmonic rhythm where chords change every two measures, facilitating long-form linear bebop phrasing.
  • Concludes with a definitive return to the home key via a standard Am7-D7-Gmaj7 cadence.
  1. Improvisation Focus Targeting guide tones (3rds and 7ths) to clearly delineate the shifting ii-V centers, especially during the modulation to Bb major.

  2. Difficulty Rating 2 (Beginner-Intermediate) โ€” The harmonic progressions are standard and predictable, though the tune is traditionally performed at a fast “up” tempo that requires technical fluidity.
