Harmonic Highlights

  • Establishes F major tonality with a clear diatonic I-ii-iii-ii chord progression (F6, Gm7, Am7, Gm7).
  • Employs a V7/ii secondary dominant (D7) to resolve to the supertonic (Gm7), adding harmonic tension and direction.
  • Features an extended section of the dominant C7, creating strong anticipation for the tonic Fmaj7 resolution.

Improvisation Focus F Major scale and its diatonic modes, specifically adapting Mixolydian for the dominant 7th chords (C7, D7).

Difficulty Rating 3 (Intermediate) - It combines fundamental diatonic progressions with a standard secondary dominant, requiring awareness of mode changes over dominant chords.
