Harmonic Highlights

  • Employs an #io7 (Abยฐ7) passing chord to bridge the Imaj7 (Fmaj7) and iim7 (Gm7), creating a smooth chromatic ascent in the bass.
  • Features a pivot modulation to the bIII tonal center (Ab major) via a iim7-V7-Imaj7 (Bbm7-Eb7-Abmaj7) sequence.
  • Utilizes modal interchange by shifting between the primary tonic F major and the key of Ab major, the relative major of the parallel minor.

Improvisation Focus Navigating the tonal shift between the F Major and Ab Major scales while targeting the common tones between the chromatic diminished chord and the tonic.

Difficulty Rating 3/5: The non-diatonic modulation to the bIII key and the frequent use of diminished passing chords require a higher level of harmonic awareness than standard diatonic progressions.
