Harmonic Highlights

  • Employs chromatic parallel motion with a descending ii-V sequence (Em7 - Ebm7 - Dm7), using the biii-7 as a passing chord to bridge the mediant and supertonic.
  • Features frequent secondary dominants, notably E7 to tonicize the vi chord (Am7) and Gm7-C7 to establish the subdominant (Fmaj7).
  • Utilizes the “backdoor” dominant (Bb7) to create a smooth transition back to the tonic or IV chord, common in late-swing era ballads.
  • Integrates ii-V cycles that modulate briefly to the subdominant key area, requiring shifts between C major and F major tonal centers.

Improvisation Focus Voice leading through ii-V-I progressions, specifically targeting guide tones (3rds and 7ths) to resolve chromatic passing chords.

Difficulty Rating 3/5: Requires the ability to navigate chromatic shifts and secondary dominants while maintaining a lyrical, ballad-tempo flow.
