Harmonic Highlights:

  • Prominent use of the IV major (Cmaj7) as an initial harmonic area, creating an open, suspended feel before the tonic G.
  • Repeated G7sus functions as a sustained tonic suspension, delaying strong resolution and adding a floating characteristic.
  • A clear Em7b5-A7 (iiø7-V7) progression strongly prepares the dominant (D) of the home key, G major.
  • The piece blends modal-like sustained chords with a standard functional harmony approach to the dominant.

Improvisation Focus: Mixolydian scale applications for dominant and suspended chords.

Difficulty Rating: 3 (Intermediate) - The blend of suspended tonics and clear ii-V progressions requires an understanding of both modal and functional harmony.
