Harmonic Highlights

  • The progression relies heavily on tonic expansion, cycling through C, C6, and Cmaj7 to create harmonic movement while remaining centered on the I chord.
  • The harmony utilizes a series of repeated ii-V cells (Dm7 - G7), providing a steady rhythmic and functional pulse characteristic of early 20th-century pop and jazz.
  • A chromatic passing diminished chord (C#°7) functions as a secondary leading-tone chord (vii°7/ii), creating a smooth voice-leading bridge from the I chord to the ii chord.

Improvisation Focus C Major Diatonicism (emphasizing the Major 6th and Major 7th intervals to match the shifting tonic colors).

Difficulty Rating 1/5 (Beginner): The structure is almost entirely diatonic with predictable cadences and a slow harmonic rhythm, making it highly accessible.
