Harmonic Highlights

  • Secondary dominant movement (III7 to VI7) creates a strong chromatic pull from the I chord (Ebmaj7) toward the ii chord (Fm7).
  • A chromatic passing diminished chord (Gb°7) is utilized to bridge the gap between the iii (Gm7) and the ii (Fm7).
  • The progression features classic functional harmony, relying on prolonged ii-V-I cadences in Eb major to anchor the tonality.

Improvisation Focus Applying the Mixolydian scale (or Lydian b7) over the secondary dominants to emphasize the non-diatonic thirds.

Difficulty Rating 2/5: The tune follows predictable functional patterns and standard jazz turnarounds, making it highly accessible for intermediate improvisers.
