Harmonic Highlights

  • The shift from Eb6 to Ebm7 utilizes modal interchange, introducing parallel minor colors that define the song’s melancholic character.
  • Secondary dominants like Gm7b5 to C7b9 function as a ii-V leading to the ii chord (Fm7), creating a sophisticated cycle of fourths.
  • The bridge modulates to the relative minor (C minor) using a series of minor ii-V-I progressions (Am7b5-D7b13-G7b9) to establish tonal gravity.
  • Chromatic voice-leading via the Gb7 (subV/ii) provides a smooth bridge between the tonic area and the Fm7-Bb7 cadence.

Improvisation Focus Voice leading through guide-tone transitions to navigate the frequent shifts between Eb major and C minor tonalities.

Difficulty Rating 3/5: While usually performed as a ballad, the dense harmonic movement and constant shifts to minor keys require a strong grasp of functional harmony.
