Harmonic Highlights

  • Utilization of secondary dominants (D7b9, G7b9) to create strong resolution paths toward the ii chord (Gm7) and the ii-V of the IV (Cm7-F7).
  • A strategic modulation to the subdominant (Bbmaj7) via a pivot ii-V, mirroring the harmonic skeleton of the Gershwin contrafact “Strike Up the Band.”
  • Frequent use of altered extensions (b9, #9, #11) which heightens the tension/release cycle within a standard AABA-derived framework.

Improvisation Focus Targeting guide tones (3rds and 7ths) to navigate the rapid secondary dominant transitions and chromatic voice leading.

Difficulty Rating 4/5: The combination of secondary dominants and the characteristically fast tempo of Lee Konitz compositions requires advanced facility with altered scales and melodic displacement.
