Harmonic Highlights:

  • The opening progression heavily features Ebmaj7 followed by Fm7/Bb, functioning as a repeated Imaj7 - V7sus4 movement in Eb major, creating a gentle, swaying rhythm.
  • A distinct ii-V-I progression (Bbm7 - Eb7 - Abmaj7) temporarily tonicizes the IV chord (Ab major), adding a common jazz harmonic embellishment.
  • The appearance of Db7 leading back to Ebmaj7 serves as a bVII7 dominant, providing a smooth, blues-inflected re-entry to the tonic.

Improvisation Focus: Eb Major Scale and its diatonic modes (e.g., Eb Lydian over Ebmaj7, F Dorian over Fm7, Bb Mixolydian over Bb7 implications).

Difficulty Rating: 3 (Intermediate) - While containing standard ii-V-I movements, the frequent V7sus4 voicings and bVII7 dominant require a nuanced harmonic understanding for effective improvisation.
