Harmonic Highlights

  • Employs standard I-VI-ii-V cycling in Eb Major, frequently utilizing secondary dominants like G7b13 to create tension leading to the vi (Cm7).
  • Incorporates a ii-V-I modulation into the subdominant key (Bbm7-Eb7-Abmaj7), shifting the tonal center briefly to IV.
  • Features a prominent “Backdoor” resolution via Abm7-Db7 (iv-bVII7) to Ebmaj7, utilizing subdominant minor colors for a smooth return to the tonic.

Improvisation Focus Guide tone mapping over functional ii-V-I cells.

Difficulty Rating 2/5: The progression follows predictable functional harmony and common cycles, making it accessible for players familiar with basic secondary dominants and subdominant minor changes.
