Harmonic Highlights

  • The A section relies on standard $ii-V-I$ cadences ($Cm7-F7-Bbmaj7$) and $V/ii$ secondary dominants ($G7$) to reinforce the Bb major tonal center.
  • The progression moves to the subdominant via a $ii-V$ in Eb ($Fm7-Bb7-Ebmaj7$), a common technique in musical theater standards.
  • The bridge features a sudden modulation to D major ($Dmaj7, Bm7, Em7, A7$), establishing a chromatic mediant relationship with the home key of Bb major.

Improvisation Focus Navigating $ii-V-I$ patterns and voice-leading through rapid key center shifts.

Difficulty Rating 3/5. While much of the tune is diatonic, the abrupt jump to D major requires the ability to pivot between distant tonalities mid-chorus.
