Harmonic Highlights

  • Employs a sequence of ii-V-I modulations to distant centers, shifting from the tonic G minor to the bVI (Eb major) and the Neapolitan bII (Ab major).
  • Utilizes chromatic dominant approach chords, such as Eb7 moving to the primary D7b9, creating tension through side-slipping.
  • Anchors the tonality with standard minor ii-V-i turnarounds (Am7b5โ€“D7b9โ€“Gm7) between modulatory sections.
  • Follows the harmonic architecture of “You Stepped Out of a Dream,” requiring navigation of major-third and half-step key relationships.

Improvisation Focus Targeting chord tones (3rds and 7ths) to define rapid modulations across shifting key centers.

Difficulty Rating 4/5: The frequent, rapid shifts to distant keys like Ab major require high-level harmonic awareness and melodic precision at typical bebop tempos.
