Harmonic Highlights

  • Employs a $iii โ€“ bIIIยฐ7 โ€“ ii$ chromatic progression (Em7 โ€“ Ebยฐ7 โ€“ Dm7), providing a smooth bridge from the mediant back to the supertonic via voice-leading.
  • Features frequent use of $V/ii$ (secondary dominant A7b13) to create strong directional movement and tension toward the Dm7 chord.
  • Incorporates the Ab7#11 as a tritone substitute ($subV7/V$), adding sophisticated non-diatonic color through the Lydian Dominant sound.
  • Maintains a strong tonal center through repetitive $ii-V-I$ patterns, grounding the chromaticism within a functional C major framework.

Improvisation Focus C Major scale navigation with specific emphasis on chromatic voice-leading and targeting chord tones during the diminished and secondary dominant passages.

Difficulty Rating 2: The progression stays rooted in C major with predictable functional movements, making it an ideal study for intermediate players to practice basic substitutions.
