Harmonic Highlights

  • Frequent use of $G#^\circ7$ as a chromatic passing chord between the $V$ or $I$ and $vi$, functioning as a secondary leading-tone chord to $Am7$.
  • Extensive secondary dominant chains ($A7 \to Dm7$ and $D7 \to G7$) that enrich the basic $I-vi-ii-V$ framework with additional melodic tension.
  • The bridge shifts focus toward the relative minor via a $ii-V-i$ progression ($Bm7b5 - E7 - Am7$), requiring a transition from $C$ major to $A$ harmonic/melodic minor scales.

Improvisation Focus Navigating $ii-V-I$ cells by targeting guide tones (3rds and 7ths) to smoothly connect the frequent secondary dominant resolutions.

Difficulty Rating 3/5; while the slow ballad tempo allows for preparation, the dense harmonic movement and frequent chromatic substitutions require a solid grasp of functional harmony.
