Harmonic Highlights

  • Diatonic stepwise bass movement (F - C/E - Dm7) creates a smooth, pop-inflected foundation typical of 1970s jazz-fusion.
  • Secondary dominant function via the minor ii-V-i (Em7b5 - A7#9 - Dm7) reinforces the relative minor (D minor) key center.
  • Frequent use of bVIImaj9 (Ebmaj9) acts as modal interchange from F Mixolydian, providing a characteristic “lift” and brightening the F major tonality.
  • Inverted dominant chords (C7/Bb) facilitate smooth voice-leading into the Am7 (iii chord), maintaining melodic flow in the bass line.

Improvisation Focus F Major Pentatonic and Hexatonic scales, utilizing Bb Lydian concepts over the Ebmaj9 chord.

Difficulty Rating 2/5: The progression is largely diatonic and repetitive, requiring only basic knowledge of minor ii-V-i resolutions and modal interchange.
