- Extended Modal Stasis: The opening 16 bars utilize prolonged Bb7sus and G7sus chords, emphasizing a post-bop modal aesthetic rather than functional dominant-to-tonic resolution.
- Tertian Root Movement: The transition from Bb7sus to G7sus moves by a minor third, creating a modern, non-diatonic shift common in Jimmy Heath’s compositions.
- Modulatory Bridge: The sequence Bm7–E7–Amaj7 introduces a remote II-V-I in A major, necessitating a rapid chromatic shift back to the Bbm7/Bb major tonal center.
Improvisation Focus Mixolydian and Sus-Pentatonic vocabulary to navigate the extended dominant pedal points.
Difficulty Rating 3/5: The long modal sections are accessible for developing soloists, but the bridge’s sudden modulations into distant keys require precise harmonic targeting.
