Harmonic Highlights:

  • Prominent use of secondary dominants (e.g., G7b9 to Cm7, F7 to Bb7) creating strong forward motion to minor and dominant chords.
  • Tonicization of the subdominant (Abmaj7) is established through a clear ii-V progression (Bbm7-Eb7).
  • Effective deployment of a leading-tone diminished chord (B07) to smoothly resolve to the vi minor chord (Cm7).
  • Features brief chromatic alterations, such as Dbm6, adding harmonic color and movement outside the diatonic framework.

Improvisation Focus: Chord-Scale Theory.

Difficulty Rating: 4 (Advanced Intermediate). Requires navigating frequent secondary dominants, tonicizations, and diminished chords, demanding a strong understanding of functional harmony.
