Harmonic Highlights

  • The progression utilizes the secondary dominant F7 (V/V) to Bb7, creating a strong directional pull toward the Eb major tonic.
  • The bridge features a sophisticated sequence of descending ii-V cycles (Bbm7-Eb7, Am7-D7, and Gm7-C7) that momentarily shift the tonal center before returning to Eb.
  • The B7 functions as a tritone substitution or a chromatic neighbor chord, providing harmonic tension and smooth voice leading into the ii-V or tonic.
  • The inclusion of Ab7 to A07 (diminished) represents a classic #IV diminished passing motion, bridging the subdominant area back to the tonic Eb6.

Improvisation Focus Guide tone voice leading (resolving 7ths to 3rds) to navigate the rapid sequential modulations in the bridge.

Difficulty Rating 2/5 โ€” The song follows a predictable AABA structure and utilizes standard functional jazz harmony, making it accessible for intermediate players.
