Harmonic Highlights

  • Starts on the IV chord (Ebmaj7), delaying tonic arrival and creating immediate harmonic momentum.
  • Employs a classic subdominant minor resolution (IVmaj7 to ivm6) or a backdoor dominant (Ab7) to return to the I.
  • Features a robust “Ragtime” cycle of secondary dominants (VI7โ€“II7โ€“V7) through G7, C7, and F7.
  • Utilizes a iiโ€“V of IV (Fm7โ€“Bb7) to transition back to the top of the form, maintaining a cyclical flow.

Improvisation Focus Chromatic voice-leading, specifically targeting the descent from the natural 3rd of the IV chord to the flat 3rd of the iv chord.

Difficulty Rating 3/5: Navigating the non-tonic start and the fast-moving secondary dominants requires a solid grasp of guide-tone resolution.
