- The repetitive Imaj7 to IV7 (Fmaj7 to Bb7) movement creates a blues-inflected tonic expansion, necessitating a melodic shift from the major 7th (E) to the minor 7th (Eb).
- Functional ii-V-I sequences (Gm7 - C7 - Fmaj7) ground the extended 72-bar form in traditional diatonic tonality.
- The Bb7 functions as a subdominant minor substitute or Lydian Dominant color, providing a sophisticated “backdoor” flavor to the primary F major key center.
Improvisation Focus The F Major Bebop Scale is essential for navigating the transition between the natural 7th on Fmaj7 and the flatted 7th on the Bb7 chord.
Difficulty Rating 2/5; the harmonic rhythm is slow and the changes are largely diatonic, though the unusual 72-bar length requires disciplined structural awareness.
