Harmonic Highlights

  • Utilizes a standard 12-bar blues form in Ab major, employing dominant 7th chords for both the I (Ab7) and IV (Db7) functions.
  • Bars 9-10 feature a classic ii-V7 turnaround (Bbm7 to Eb7), replacing the traditional V-IV movement common in earlier blues forms.
  • The harmony remains static on Ab7 for the first four bars, providing a stable foundation for the repetitive, riff-based melodic structure.

Improvisation Focus Ab Blues Scale (Ab, B, Db, D, Eb, Gb) and riff-based motivic development.

Difficulty Rating 2/5; the predictable 12-bar structure and standard ii-V cadence make it highly accessible for intermediate improvisers.
