Harmonic Highlights:

  • The D7 chord acts as a secondary dominant (V7/ii), creating a strong pull to the Gm7 (ii minor) before the ii-V-I.
  • A chromatic C#0 diminished chord provides tension, functioning as a leading-tone diminished to Dm7 (iii minor).
  • The Dm7-G7-C7 progression serves as an extended turnaround, utilizing the V7/V (G7) before the primary dominant (C7).

Improvisation Focus: Arpeggios and chord tones to clearly outline the functional harmony of each chord.

Difficulty Rating: 3 (Intermediate) – It features common ii-V-I progressions alongside secondary dominants and a chromatic diminished chord, requiring moderate harmonic understanding.
