Harmonic Highlights

  • Employs a near-complete diatonic cycle of fourths (vi7–ii7–V7–Imaj7–IVmaj7–viiø7–III7), providing a logical and relentless sense of forward motion.
  • Fluidly navigates the relationship between the relative major (C) and natural minor (A), utilizing a minor ii-V-i (Bm7b5–E7b9) to tonicize the A minor center.
  • Utilizes secondary dominants like A7 (V7 of ii) to create chromatic leading tones that resolve predictably into the next sequence of fourths.

Improvisation Focus The C Major / A Natural Minor scale, requiring only localized adjustments for the G# (on E7) and C# (on A7) to address the functional non-diatonic tones.

Difficulty Rating 2/5 - The predictable root movement and diatonic nature make it an ideal introductory tune for students learning to navigate jazz cycles.
