Harmonic Highlights

  • Frequent use of tonic prolongations (C, C6, Cmaj7) establishes a clear C major tonality with added color.
  • The progression heavily relies on the foundational II-V-I (Dm7-G7-C) in C major, appearing multiple times.
  • A C#° diminished 7th chord provides a brief, non-diatonic moment, functioning as a vii°7/ii leading to Dm7.
  • The harmony is predominantly diatonic, making it highly accessible yet melodically rich.

Improvisation Focus C Major scale and its diatonic modes (Dorian over Dm7, Mixolydian over G7).

Difficulty Rating 2 (Beginner-Intermediate) - The clear II-V-I movements and C major key are accessible, with the C#° chord introducing a common chromatic embellishment.
