Harmonic Highlights

  • Utilization of secondary dominants like G7 leading to Cm7 (VI7 to iim7) creates strong directional pull within the Bb major tonality.
  • The Bbº7 functions as a common-tone diminished chord, providing chromatic tension that resolves back to the tonic Bbmaj7.
  • Chromatic sequences involving Em7b5 to Eb7 to Dm7 demonstrate sophisticated modal interchange and subdominant minor functionality typical of Bacharach’s style.

Improvisation Focus Chord Tone Soloing to navigate frequent non-diatonic shifts and deceptive resolutions.

Difficulty Rating 4/5: The irregular phrase lengths and shifting tonal centers require advanced harmonic navigation and sensitivity to unconventional song structures.
