Harmonic Highlights:

  • Classic III-7 (Em7) to II-7 (Dm7) progression effectively uses a chromatic diminished passing chord (Eb07).
  • Frequent tonicization of the subdominant (F major) through standard ii-V-I movement (Gm7-C7-Fmaj7).
  • Features a dramatic chromatic modulation to Db major, initiated by an Ab chord resolving deceptively through an Abaug.

Improvisation Focus: Chord tones and guide tones.

Difficulty Rating: 3 (Intermediate). The tune combines standard ii-V-I progressions with notable chromaticism and a significant, abrupt modulation, requiring focused harmonic understanding.
