Harmonic Highlights:

  • Dominant use of the I-vi-ii-V progression (Bbmaj7-Gm7-Cm7-F7) clearly establishes and reaffirms the Bb major tonic.
  • The Dm7-G7-Cm7-F7 sequence functions as a III-VI-ii-V turnaround, creating forward harmonic momentum towards the tonic.
  • A strong ii-V-i progression (Am7b5-D7b9-Gm7) effectively tonicizes the relative minor, G minor, adding harmonic depth.

Improvisation Focus: Chord Tone Targeting over Functional Harmony.

Difficulty Rating: 3 (Intermediate). Features clear ii-V-I progressions, standard turnarounds, and a well-defined tonicization of the relative minor, making it accessible with some harmonic understanding.
