Harmonic Highlights

  • The ‘A’ section features a recurring i-V7/F (Gm7-C7) progression, where C7 serves as a secondary dominant targeting F.
  • The harmony clearly tonicizes Bb major (the relative major, bIII) in the ‘B’ section, prominently utilizing the V7-I (F7-Bb) movement.
  • A pre-dominant chain (G7-C7, functioning as V/V-V) builds harmonic tension, setting up a strong return towards F.

Improvisation Focus Mixolydian scales over the numerous dominant 7th chords.

Difficulty Rating 3 (Intermediate). Requires navigating various secondary dominants and temporary tonicizations without overly complex rhythmic or harmonic structures.
