Harmonic Highlights

  • The use of Dbm7 functions as a non-diatonic bvii7, providing a striking modal interchange that creates the song’s signature “Spanish” or exotic color within Eb major.
  • Standard ii-V-I resolutions (Fm7 to Bb7 to Ebmaj7) anchor the harmonic structure, ensuring a traditional jazz vocabulary despite the chromatic excursions.
  • The secondary dominant C7b9 (V/ii) introduces tension and reinforces the move to the supertonic (Fm7), a classic bebop device for navigating the diatonic landscape.

Improvisation Focus Modal shifting: Transitioning between Eb Major and Db Dorian (over the Dbm7) to accurately capture the characteristic chromatic lift of the melody.

Difficulty Rating 2/5: The tune is largely diatonic and follows standard functional harmony, with only the brief non-diatonic Dbm7 requiring specific modal attention.
