- Utilizes a foundational I-vi-ii-V progression in Bb major, integrating altered dominants (F7#9) to infuse blues-oriented dissonance into the lyrical structure.
- Employs frequent tritone substitutions and backdoor dominants (Ab7 to Gm7 or Bb), facilitating smooth chromatic descending basslines and sophisticated voice leading.
- Features sudden tonicization of remote keys, such as the modulation to Db major, demonstrating Gershwin’s characteristic use of chromatic mediant relationships.
- Incorporate minor ii-V sequences (Em7b5 to Eb7 to Dm7) that provide a poignant, modal interchange quality typical of the Great American Songbook.
Improvisation Focus Chord Tone Soloing (Arpeggiation) to accurately navigate the rapid shifts in tonal centers and non-diatonic substitutions.
Difficulty Rating 4/5: The dense harmonic rhythm, frequent modulations, and use of altered extensions require an advanced understanding of functional harmony and precise melodic targeting.
