Harmonic Highlights

  • Frequent use of the iii-VI7 progression (Am7–D7) acts as a secondary dominant sequence targeting the supertonic (Gm7).
  • The II7 (G7) chord functions as a V/V, providing a classic swing-era approach to the primary dominant C7.
  • Use of the G#ΒΊ7 passing diminished and Gb7b5 tritone substitution adds chromatic tension and smooth voice leading back to the tonic F.

Improvisation Focus F Major Bebop Scale.

Difficulty Rating 2; the piece utilizes predictable cycle-of-fifths movements and stays firmly rooted in F major, making it ideal for practicing secondary dominants and basic substitutions.
