Harmonic Highlights

  • The Gm7-C7 to Fm7-Bb7 sequence employs a descending whole-step ii-V chain, providing a sophisticated transition toward the subdominant area.
  • Chromaticism is defined by the Em7-Eb°7-Dm7-G7 turnaround, utilizing the Eb°7 as a functional bIII°7 passing chord between the iii and ii minor chords.
  • The bridge shifts the tonal center to the mediant minor (E minor) via a ii-V-I (F#m7b5-B7b9-Em7), introducing a darker harmonic contrast to the C major sections.
  • Integration of the “backdoor” dominant (Bb7) and tritone substitution (Db7#11) adds modern harmonic tension and lushness to standard tonic resolutions.

Improvisation Focus Voice leading through chromatic guide-tone connections.

Difficulty Rating 3/5: While usually performed as a slow ballad, the frequent modulations and chromatic passing chords require advanced navigation of secondary dominants and non-diatonic scales.
