Harmonic Highlights:

  • The prominent Imaj7 to IVmaj7 (Abmaj7 to Dbmaj7) provides a characteristic “plagal” ballad sound, emphasizing lyrical melodic motion.
  • A sophisticated minor ii-V-i progression (Gm7b5 - C7b9 - Fm7) temporarily tonicizes the relative minor (Fm), introducing dramatic tension and color.
  • Effective chromatic voice leading is evident through the use of a passing diminished chord (B07 between Bbm7 and Ab6/C), adding harmonic interest.
  • The recurring Eb7sus chord adds a gentle, suspended quality to the dominant before its smooth resolution to the tonic.

Improvisation Focus: Chord tone outlining and guide tone resolution through the diverse harmonic changes.

Difficulty Rating: 4 (Advanced Intermediate). It demands precise navigation of temporary minor tonicizations and chromatic passing chords within a ballad tempo.
