Harmonic Highlights

  • Employs standard ii-V-I progressions in Eb Major to establish a firm hard-bop tonal center.
  • Features a diatonic descending bass line (Eb–D–C–Bb) that provides linear motion through the tonic and submediant harmonies.
  • Utilizes a distinctive Abm(maj7) as a minor iv chord, introducing modal interchange and a sharp natural 7th (G) that pulls toward the tonic.
  • Incorporates a iii-VI-ii-V turnaround (Gm7–C7–Fm7–Bb7) to create cyclical momentum back to the head.

Improvisation Focus Applying the Ab Melodic Minor scale over the Abm(maj7) chord to highlight the tension between the minor 3rd and major 7th.

Difficulty Rating 3/5. While the ii-V-I foundations are accessible, the descending chromatic movement and the specific minor-major chord quality require precise harmonic navigation.
