  • Sophisticated tonic minor development through Cm, Cmb6, Cm6, and Cm7, employing chromatic inner-voice movement for varied harmonic color.
  • Clear modulation to the relative major via the prominent Fm7-Bb7-Ebmaj7 ii-V-I progression.
  • Extensive use of altered dominants (G7b9, C7b9, D7b9) and iiø-V progressions, creating tension and leading to various temporary tonal centers.
  • Intriguing chromaticism in sequences like Em7b5 to Eb7#11, hinting at tritone substitution or temporary shifts.

Improvisation Focus: C Harmonic Minor and its related modes/altered scales.

Difficulty Rating: 4 (Advanced). Its frequent use of altered dominants, iiø-V progressions to temporary tonal centers, and unexpected substitutions demands a strong grasp of harmonic flexibility.
