Harmonic Highlights

  • Extensive use of secondary ii-V chains (iii-VI7 to ii-V7) creates cyclical momentum typical of Benny Golson’s sophisticated Hard Bop arrangements.
  • Minor ii-V interpolations (Bm7b5–E7b9) provide chromatic coloration and functional pull toward the ii chord (Am7).
  • The juxtaposition of C#m7b5 and Am7b5 utilizes half-diminished structures to bridge tonic and dominant areas via chromatic root movement.

Improvisation Focus Continuous voice leading through ii-V-I chains, specifically targeting 3rds and 7ths to navigate the rapid secondary dominant shifts.

Difficulty Rating 3/5: While the G major tonal center is stable, the frequent secondary dominants and minor ii-V substitutions require precise navigation of chromatic alterations.
