Harmonic Highlights

  • Employs a classic I-vi-ii-V turnaround in Eb major, often embellished with an E°7 passing chord to create chromatic bass movement between the I and ii.
  • Utilizes a secondary ii-V (Bbm7–Eb7) to briefly tonicize the subdominant (Abmaj7), providing a standard but effective harmonic lift.
  • Incorporates a III7-vi progression (G7 to Cm), introducing temporary minor-key tension via the secondary dominant of the relative minor.

Improvisation Focus Eb Major scale and its modes, prioritizing guide-tone resolution (3rds and 7ths) to navigate the frequent functional cadences.

Difficulty Rating 2/5: The song’s reliance on predictable diatonic patterns and standard jazz turnarounds makes it an accessible entry point for learning functional harmony.
