Harmonic Highlights

  • Frequent use of I-VI7-ii-V7 (F6-D7-Gm7-C7) and iii-VI7-ii-V7 (Am7-D7-Gm7-C7) cycles, providing continuous circular motion through secondary dominants.
  • Tonicization of the supertonic (Gm7) via the V7/ii (D7), which maintains harmonic tension and chromatic interest within the A sections.
  • A clear modulation to the subdominant (Bb major) in the bridge, initiated by a ii-V7 pivot (Cm7-F7) to facilitate a tonal shift.

Improvisation Focus Guide tone voice leading (3rds and 7ths) to navigate the repetitive I-VI-ii-V turnarounds effectively.

Difficulty Rating 2/5; the predictable harmonic rhythm and reliance on standard diatonic cycles make it an ideal entry-point for practicing foundational jazz vocabulary.
