  • Clear minor ii-V-i progressions, exemplified by Bm7b5 - E7b13 - Am7, establishing a strong temporary tonicization of the submediant minor.
  • Rich harmonic color from extensions like Fmaj7#11, B7#9, and E7b13, adding tension and contemporary flavor.

Improvisation Focus: Altered Scale

Difficulty Rating: 4 (Advanced Intermediate) - Requires precise navigation of multiple temporary tonicizations and proficient use of altered dominant scales.
