Harmonic Highlights

  • Employs a recurring ii-V-i in A minor that frequently alternates with a II7 chord (D7), creating a strong A Dorian modal center.
  • Features sequential ii-V progressions (Dm7-G7 followed by Em7-A7) to navigate smoothly between A minor and the relative C major.
  • Utilizes a cyclical turnaround structure that relies on diatonic movement within the A minor/C major landscape, providing a stable but driving harmonic rhythm.

Improvisation Focus A Dorian Scale (A, B, C, D, E, F#, G).

Difficulty Rating 3/5: While the chord changes are repetitive and logical, the performer must shift fluidly between F natural and F# to accommodate the alternating minor and dominant functions.
