Harmonic Highlights

  • Employs a classic I - #i°7 - ii movement (Ebmaj7 - E°7 - Fm7), utilizing the diminished chord as a functional chromatic connector.
  • Features a secondary dominant transition to the subdominant (Eb7 to Abmaj7), immediately followed by a #IV°7 (A°7) passing chord for chromatic lift.
  • Relies on repetitive I-vi-ii-V7 cycles in Eb major, providing a highly stable diatonic framework typical of the Great American Songbook.

Improvisation Focus Eb Major Bebop Scale.

Difficulty Rating 2/5. The progression uses standard functional harmony and predictable chromatic passing tones, making it an accessible entry point for mastering basic jazz vocabulary.
