Harmonic Highlights

  • Uses a prominent minor plagal cadence (Abm6) to create a soulful, gospel-inflected resolution back to the Eb tonic.
  • Features a secondary ii-V-i progression (Am7b5 โ€“ D7b9 โ€“ Gm7) that briefly tonicizes the mediant minor, shifting the tonal center away from Eb major.
  • Employs chromatic voice-leading via a tritone substitute (Gb7 for C7) during the turnaround, facilitating a smooth descent from the iii chord to the ii-V.

Improvisation Focus

The Eb Blues scale, integrated with G Harmonic Minor to navigate the secondary ii-V-i modulations.

Difficulty Rating

3/5 โ€“ The piece blends straightforward diatonic melodies with sophisticated minor-key excursions and tritone substitutions that require precise harmonic targeting.
