  • Prominent use of the I-VI-II-V progression (C6-A7-D7-G7) establishes a foundational jazz sound.
  • A iiø7-V7b9-i progression (F#m7b5-B7b9-Em7) briefly tonicizes the relative minor, adding harmonic tension and release.
  • An Eb07 functions as a chromatic diminished passing chord (Em7-Eb07-Dm7), creating distinctive voice leading and chromatic interest.
  • Temporary tonicization of the subdominant via C7-F6 briefly expands the harmonic landscape.

Improvisation Focus: Mastery of dominant 7th alterations and minor ii-V-i arpeggios.

Difficulty Rating: 3 (Intermediate) – While many changes are standard, the inclusion of iiø7-V7b9 and chromatic diminished chords requires a solid grasp of altered harmony.
