Harmonic Highlights:

  • Features a characteristic secondary dominant E7 (V/ii) propelling the harmony towards Am7, a common jazz ii-V setup.
  • Includes a clear tonicization of the subdominant (IV) through the Dm7-G7-Cmaj7 (ii-V-I in C) progression.
  • Employs the C#07 diminished chord, functioning as a chromatic passing chord or leading-tone diminished to the dominant (D7).

Improvisation Focus: Navigating ii-V-I progressions and temporary modulations.

Difficulty Rating: 3 (Intermediate). It requires comfortable navigation of ii-V-I progressions and a temporary modulation to the subdominant.
