Harmonic Highlights

  • Frequent use of I-VI-ii-V cycles (Ebmaj7-C7-Fm7-Bb7) provides a stable, rhythmic foundation typical of early 20th-century standards.
  • The Abm7 chord functions as a minor subdominant (iv), creating a characteristic chromatic pull (Cb to Bb) toward the tonic.
  • A modulation to C major (via G7) introduces a temporary shift to the parallel major of the relative minor, requiring a distinct pivot in tonal orientation.

Improvisation Focus Eb Major Bebop scale.

Difficulty Rating 2/5: The predictable turnaround structure and clearly prepared modulations make it highly accessible for intermediate soloists.
