Harmonic Highlights

  • Employs a ii-V of IV (Bbm7-Eb7 to Abmaj7) followed by a classic backdoor resolution (Abm7-Db7) to return to the tonic.
  • Utilizes secondary dominants (F7, G7) to create brief modulations to Bb major and the relative minor (Cm7), expanding the harmonic palette.
  • Features a sophisticated bridge structure that cycles through multiple key centers, including G major, via rapid ii-V patterns.

Improvisation Focus Voice-leading through frequent ii-V-I progressions, specifically targeting guide tones (3rds and 7ths) to outline the shifting tonal centers.

Difficulty Rating 3/5: The ballad tempo allows for preparation, but the frequent modulations and backdoor dominant substitutions require intermediate harmonic knowledge.
