Harmonic Highlights

  • Utilizes a deceptive resolution of G7 (V7/vi) to Ab7 (IV7), creating a gospel-inflected “side-step” motion rather than a standard resolution to Cm.
  • Features a chromatic ii-V descent (Bbm7 to Am7b5 to Ab7) that facilitates smooth voice-leading toward the subdominant area.
  • Incorporates a minor line cliché (Cm - Cm/maj7 - Cm7) that provides internal melodic movement over a static vi chord.
  • Frequent use of non-functional dominant 7ths (I7, IV7) blends traditional 32-bar form with a sophisticated hard-bop blues language.

Improvisation Focus Eb Major Blues scale combined with chord-tone targeting to navigate the frequent secondary dominant shifts.

Difficulty Rating 3/5: The moderate tempo is accessible, but the non-diatonic shifts and chromatic sequences require precise harmonic awareness beyond basic scale patterns.
