Harmonic Highlights

  • The #iv°7 chord (F#°7) acts as a chromatic connector, creating a smooth transition from the tonic (Cmaj7) to the ii-V7 progression (Dm7-G7).
  • A descending chromatic sequence of dominant chords (B7-Bb7-A7) utilizes tritone substitutions and secondary dominants to resolve strongly toward the ii chord (Dm7).
  • The G7#5 introduces altered dominant colors, specifically drawing from the Whole-Tone or Altered scale to heighten tension before the tonic resolution.
  • The movement from IV (Fmaj7) through #iv°7 to the tonic illustrates a classic swing-era harmonic cliché for delayed resolution.

Improvisation Focus The C Major Bebop scale, emphasizing chromatic passing tones to bridge the gaps between the diatonic melody and the secondary dominant chords.

Difficulty Rating 2/5: While the chromaticism requires some agility, the song remains firmly anchored in C major functional harmony without complex modulations.
