Harmonic Highlights

  • Employs tonic prolongation via I-vi (Cmaj7-Am7) before moving into a iii-V7/iii-iii sequence (Em7-B7b9-Em7).
  • Utilizes secondary dominant cycling (A7-Dm7-G7) to reinforce the C major resolution.
  • Features a minor ii-V-i (Bm7b5-E7b9-Am7) to pivot to the relative minor key area.
  • Uses chromatic passing chords (Abm7) for smooth parallel voice leading between Am7 and Gm7.

Improvisation Focus Applying Harmonic Minor scales over dominant chords (specifically V7/vi and V7/iii) to emphasize altered tensions.

Difficulty Rating 3/5: The piece requires navigating frequent shifts between C major and its relative minor via secondary dominants and chromatic passing chords.
