Harmonic Highlights

  • Frequent secondary dominants (e.g., B7b13 to Em7) and non-diatonic ii-V progressions (Cm7-F7 to Bb) drive temporary tonal shifts.
  • Significant modal interchange is evidenced by chords like Gm7 (bVIIm7) and Ebm7 (biiim7), adding rich harmonic color and tension.
  • A strong iiø7-V7-iø7 sequence (G#m7b5-C#7b9-F#m7b5) establishes a temporary F# minor key center, far removed from the tonic C major.
  • Chromatic minor chord movements, like Dm7-Ebm7, provide smooth, non-diatonic voice leading and harmonic interest.

Improvisation Focus Altered Scale application on dominant chords.

Difficulty Rating 4 (Advanced Intermediate). Its frequent modulations, altered dominants, and distant key centers demand sophisticated harmonic understanding and execution.
