Harmonic Highlights

  • Extended Circle of Fifths: The progression relies on a classic VI7-II7-V7-I chain (D7-G7-C7-F), a hallmark of the New Orleans and Swing eras.
  • Chromatic Tritone Substitutions: The use of Db7 to C7 and Ab7 to G7 functions as subV7 movements, providing smooth chromatic voice leading into target dominant chords.
  • Diminished Passing Motion: The F#ยฐ chord acts as a chromatic connector between the tonic F and the II7 (G7), heightening harmonic tension before resolution.

Improvisation Focus Secondary Dominant Arpeggios: Mastering the transition through the cycle of fourths (D7-G7-C7) using Mixolydian or dominant 7th arpeggios.

Difficulty Rating 2/5: The predictable cycle of fourths and clear secondary dominants make it an accessible entry point for learning functional jazz harmony.
