Harmonic Highlights

  • Uses a standard I-vi-ii-V cycle in Eb major to anchor the tonality before transitioning to the subdominant.
  • Incorporates a ii-V to the IV chord (Bbm7-Eb7 to Ab6) followed by a backdoor dominant (Db7) for a sophisticated blues-inflected resolution.
  • Employs chromatic diminished passing chords (Edim7, Adim7) to bridge diatonic gaps and facilitate smooth voice leading.
  • Utilizes a bVI7 (B7) substitute dominant to create a strong chromatic approach to the primary V7 (Bb7).

Improvisation Focus Eb Major Pentatonic and Blues scales, emphasizing chord tones during the ii-V-I cadences.

Difficulty Rating 2/5: The harmonic structure is largely diatonic with predictable secondary dominants, making it highly accessible for developing players at its typical ballad tempo.
