Harmonic Highlights:

  • The prominent use of Cm/maj7 as the tonic creates a distinct minor sound with a major 7th, suggesting a C melodic minor tonality.
  • Recurring D7-G7b13-Cm/maj7 progressions firmly establish C minor as a primary, though modified, harmonic destination.
  • A clear modulation to Ab major is presented via a Bbm7-Eb7-Abmaj7 II-V-I, adding significant harmonic depth and contrast.
  • The Db7 functions as an out-of-key dominant, potentially a tritone substitute for G7 or a V/Gb.

Improvisation Focus: C Melodic Minor scale.

Difficulty Rating: 4 (Advanced Intermediate) - The blend of minor/major tonality and clear modulations requires strong modal and altered scale proficiency.
