Harmonic Highlights:

  • The Bbm7-Eb7-Abmaj7 progression introduces a subdominant minor ii-V-I, temporarily modulating to the IV.
  • The A07 chord functions as a chromatic diminished chord, creating tension and leading to the Gm7.
  • Sustained Abm6 for two measures provides a distinctive minor iv sound, enriching the subdominant color.
  • The Cm - Cm/maj7 - Cm7 - F7 progression features a descending chromatic line within the vi chord, transitioning into a ii-V to the dominant.

Improvisation Focus: Navigating various II-V-I progressions and their associated modes.

Difficulty Rating: 3 (Intermediate). The tune incorporates standard jazz harmony with several non-diatonic chords and common temporary modulations, requiring moderate harmonic awareness.
