Harmonic Highlights

  • Establishes the tonic Bb major through classic ii-V-I progressions.
  • Features a chromatic descending minor 7th chord (Gbm7) as a passing harmony, leading into a ii-V.
  • Strong tonicization of the subdominant (IV chord, Ebmaj7) via its respective ii-V-I progression (Fm7-Bb7-Ebmaj7).
  • Incorporates a V7/V (C7) leading to the dominant function, creating harmonic tension.

Improvisation Focus Navigating secondary dominant functions and temporary tonicizations.

Difficulty Rating 3 (Intermediate) - Requires adapting to temporary key centers and a subtle chromatic passing chord within a standard jazz framework.
