Harmonic Highlights

  • Employs a minor ii-V-i (F#m7b5 - B7b9 - Em7) to tonicize the relative minor, providing a somber shift from the G major home key.
  • Features a secondary ii-V leading to the IV chord (Dm7 - G7 - Cmaj7), followed by a minor subdominant (Cm6) for classic “sentimental” chromaticism.
  • Utilizes chromatic passing chords like Bb°7 and the Eb7 tritone substitute to create smooth voice leading and linear bass motion between primary diatonic functions.

Improvisation Focus Major and Minor ii-V-I cell integration, specifically targeting the b6 (Eb) over the Cm6 chord to highlight the shift to the parallel minor.

Difficulty Rating 3/5; the progression follows logical functional harmony but requires navigating frequent modulations to the relative minor and the subdominant key areas.
