Harmonic Highlights

  • Prominent use of the Db7 (bII7) as a tritone substitution for the V7, frequently appearing immediately after the tonic, creating a strong chromatic pull.
  • The extended F7sus progression generates prolonged dominant tension, delaying resolution and contributing to harmonic ambiguity.
  • Unconventional dominant relationships, such as Db7 followed by A7, and the C13 to A7 leading to Dmaj7, introduce sudden modulations or parallel major shifts.

Improvisation Focus Navigating tritone substitutions and chromatic alterations.

Difficulty Rating 5 (Advanced) due to frequent, often abrupt, modulations and unconventional dominant relationships demanding precise scale and arpeggio application.
