Harmonic Highlights:

  • Employs classic Imaj7-ii7-V7 progressions in F major, establishing the primary tonality.
  • Features a temporary shift to the subdominant Bb major via a clear ii7-V7-Imaj7 progression (Cm7-F7-Bbmaj7).
  • Utilizes an Eb7 (bVII7 of F, or V/IV) resolving to the ii7-V7 in F (Gm7-C7), adding a backdoor or chromatic color.
  • Showcases a distinct modulation up a major third from F major to A major, clearly outlining its new tonic and ii7-V7-I progression.

Improvisation Focus: Navigating the abrupt and significant modulation to A major by outlining its new tonal center.

Difficulty Rating: 4 (Intermediate-Advanced) The dramatic modulation up a major third requires agile harmonic adaptability for both soloing and accompaniment.
