Harmonic Highlights

  • Frequent movement from I (Ebmaj7) to IV (Abmaj7) creates the characteristic “dreamy” subdominant atmosphere of the A section.
  • The bridge utilizes a classic minor ii-V-i sequence (Dm7b5 - G7b9 - Cm7) to shift the tonal center toward the relative minor.
  • Inclusion of the B7#11 acts as a chromatic approach or tritone substitute (subV/V), creating a sophisticated lead-in to the primary ii-V-I.
  • The harmony relies on standard diatonic cycling, primarily utilizing ii-V-I cells in Eb major to reinforce the home key.

Improvisation Focus Navigating the transition between Eb Major scales and C Harmonic Minor over the secondary ii-V-i progression.

Difficulty Rating 2/5: The tune follows a predictable AABA structure with standard secondary dominants, making it highly accessible for intermediate improvisers.
