Harmonic Highlights

  • Utilizes a 12-bar blues framework featuring a chromatic #IV diminished chord (Bยฐ7) to bridge the IV7 (Bb7) back to the tonic.
  • Employs an extended turnaround sequence (Am7โ€“D7โ€“Gm7โ€“C7) using secondary dominants to create a functional cycle of fourths movement.
  • Integrates blues-inflected Mixolydian harmony with standard bebop ii-V-I cells, characteristic of the hard bop era’s approach to the blues.

Improvisation Focus F Major Blues scale combined with chord-tone targeting (3rds and 7ths) to navigate the rapid turnaround.

Difficulty Rating 2/5; the structure is a familiar blues variant, though the secondary dominants require basic proficiency in navigating quick ii-V-I substitutions.
