Harmonic Highlights

  • Employs an AABA “Rhythm Changes” framework in Ab, utilizing frequent ii-V-I turnarounds (Bbm7-Eb7-Abmaj7).
  • Features a chromatic B°7 passing chord between the Imaj7 and iim7, facilitating smooth ascending linear voice leading.
  • The bridge follows a standard cycle-of-fourths progression using secondary dominants (C7 to Fm, followed by Bb7 to Eb7) to reset the tonal center.

Improvisation Focus Ab Major Bebop Scale.

Difficulty Rating 3/5. While the harmonic vocabulary is foundational to swing, the typical brisk tempo and requirement for precise syncopation demand significant technical facility.
