Harmonic Highlights

  • Extensive use of secondary dominants, specifically D7 (V/V) and C7 (V/IV), creates a classic “circle of fifths” drive characteristic of early jazz and ragtime.
  • The sequence of F7 to Bb6 functions as a move to the subdominant (IV) followed by a bVII substitution, introducing blues-inflected modal interchange.
  • Harmonic tension is generated through dominant seventh prolongation rather than standard minor ii-V-I cadences, emphasizing Mixolydian colors throughout.

Improvisation Focus Chord-tone soloing emphasizing 3rds and 7ths to navigate the rapid secondary dominant transitions.

Difficulty Rating 2/5 โ€” The progression follows a predictable functional logic and repetitive structure, though navigating the constant dominant changes requires clear voice leading.
