Harmonic Highlights

  • Predominant use of the diatonic ii-V-I progression (Cm7-F7-Bb6) firmly establishing Bb major.
  • Frequent extension of the ii-V-I to the vi chord (Gm7), forming a standard diatonic ii-V-I-vi phrase.
  • A clear tonicization of the IV chord is evident with the Fm7-Bb7-Eb6 progression, serving as a ii-V-I in Eb major.

Improvisation Focus Navigating ii-V-I progressions.

Difficulty Rating 2 - The harmonic rhythm is accessible and relies on foundational diatonic and common secondary ii-V-I movements, making it suitable for developing improvisers.
