Harmonic Highlights:

  • Frequent I-VI-ii-V turnarounds utilize the C7b9 secondary dominant to intensify the resolution to the ii chord (Fm7).
  • A chromatic descending line (Gm7 - Gb7 - Fm7) functions via a tritone substitution (Gb7 replacing C7) for smooth voice leading.
  • Inclusion of the IV7 (Ab7) provides “backdoor” dominant flavor, momentarily pulling away from the purely diatonic Eb major center.
  1. Improvisation Focus: Eb Major Bebop scale to bridge the gap between diatonic stability and the frequent dominant-to-minor resolutions.

  2. Difficulty Rating: 2/5; the tune relies on standard jazz clichés and predictable cadences, making it approachable for developing improvisers.
