Harmonic Highlights

  • The A-section centers on a classic I-ii-V-I turnaround (Fmaj7-Gm7-C7) typical of 32-bar AABA song forms.
  • A secondary ii-V (Cm7-F7) leads to the subdominant (Bbmaj7), followed by a bVII7 “backdoor” dominant (Eb7) that resolves back to F major.
  • The bridge features a sudden tertiary modulation to A major (the major III), utilizing sequential ii-V-I progressions (Bm7-E7-Amaj7) before returning to the home key.

Improvisation Focus

Navigating the rapid tonal shift from F major to A major and back during the bridge transition.

Difficulty Rating

3/5. The A-sections are beginner-friendly diatonic swing, but the bridge’s abrupt modulation to a distant key requires intermediate harmonic targeting.
