Harmonic Highlights

  • Employment of the bII7 (Db7) as a tritone substitute for G7, creating a smooth chromatic descent to the dominant C7.
  • Integration of common-tone diminished chords (Cยบ7 and Fยบ7) to add harmonic color and internal voice-leading interest to the tonic and dominant pillars.
  • Secondary dominant movements (F7) that imply a brief tonicization of the subdominant, reinforcing the cyclical nature of the swing-era progression.
  • Turnaround tension via altered dominant voicings (C7#5#9), facilitating a strong melodic resolution back to the Fmaj7 tonic.

Improvisation Focus Chord tone targeting utilizing the F Major Bebop scale to bridge the gap between diatonic stability and chromatic passing tones.

Difficulty Rating 2/5; the predictable structural layout and clear diatonic cadences make it an ideal entry point for practicing secondary dominants and basic chromatic substitutions.
