Harmonic Highlights

  • Stepwise diatonic movement (F6–Gm7–Am7) establishes a gospel-inflected soul-jazz foundation typical of the Hard Bop era.
  • Abrupt modulation to the flat-mediant (Ab major) via a ii-V (Bbm7–Eb7) creates a bright tonal shift away from the F major tonic.
  • Frequent use of secondary dominants (G7, D7) creates a cyclical “circle of fifths” motion that facilitates smooth resolutions back to the primary key.

Improvisation Focus F Major Blues scale combined with diatonic ii-V-I cellular patterns.

Difficulty Rating 3/5: The moderate tempo is accessible, but the sudden shifts to the bIII key center require agile navigation of non-diatonic changes.
