Harmonic Highlights

  • The progression utilizes Ab7 (bVI7) as a common-tone substitute or chromatic approach leading into the Dm7-G7 (ii-V) turnaround, creating sophisticated tension.
  • The shift to Bbm7-Eb7-Abmaj7 represents a brief modulation to the subdominant major key, typical of sophisticated ballads to vary the harmonic landscape.
  • The Am7-D7#11 sequence acts as a secondary dominant (V/V) that introduces a Lydian Dominant color before resolving back toward the tonic center.
  • Frequent use of Cm6 and Am7b5 highlights a minor-major harmonic relationship, emphasizing the C Melodic Minor tonality over the C minor tonic.

Improvisation Focus C Melodic Minor and G Altered scales to effectively bridge the gap between the dark minor tonic and the chromatic dominant resolutions.

Difficulty Rating 3/5 โ€“ Navigating the quick transitions between minor ii-V-I sequences and the subdominant modulation requires precise linear voice leading.
