Harmonic Highlights

  • Frequent modal interchange between the C minor verse and the C major chorus, creating a sophisticated push-pull of tonality.
  • Integration of the Neapolitan (bII) chord (Db major) functioning as a chromatic predominant leading toward the V7.
  • Extensive use of secondary dominants (C7 to Fm; D7 to G7) that reinforce temporary tonal centers before returning to the tonic.
  • Chromatic approach chords and cycle-of-fifths movement bridge the gap between the minor-heavy introduction and major-centric sections.

Improvisation Focus Modal Interchange Navigation: Mastery of switching fluently between C Aeolian/Dorian scales and the C Major/Ionian landscape.

Difficulty Rating 3/5: The challenge lies in managing the rapid shifts between parallel keys and navigating the specific chromaticism typical of Cole Porterโ€™s compositional style.
