Harmonic Highlights

  • Utilizes a modified 12-bar blues framework in Eb Major that prioritizes dominant 7th functionality on the I, IV, and V chords for a traditional blues-bop aesthetic.
  • Features an extended turnaround sequence via a cycle of fourths (Dm7โ€“Gm7โ€“Cm7โ€“F7), functioning as a series of secondary ii-V progressions that intensify the resolution to the dominant.
  • Employs frequent movement between the tonic (Eb7) and subdominant (Ab7), requiring smooth voice leading of the b7 to the 3rd during transitions.

Improvisation Focus

The Eb Major Bebop Scale (or combining Eb Mixolydian with the Eb Blues scale) to navigate the dominant cycles.

Difficulty Rating

3/5: While the underlying blues form is accessible, the rapid tempo and chromatic turnarounds require intermediate-level technical facility and precise harmonic targeting.
