  • Prominent use of diatonic ii-V-I progressions in Eb major, establishing a strong tonal center.
  • Incorporates a direct Imaj7 to IVmaj7 movement (Ebmaj7-Abmaj7).
  • Features a bvim6 - bII7 chord progression (Abm6-Db7), adding chromatic color and backdoor dominant possibilities.
  • Employs a descending secondary dominant chain Dm7-G7-C7, suggesting temporary tonicization away from Eb.

Improvisation Focus: Eb Major Scale

Difficulty Rating: 3 (Intermediate) – The blend of standard ii-V-I with chromatic substitutions and sequential dominant extensions requires a solid grasp of fundamental harmony and voicings.
