Harmonic Highlights:

  • Utilizes a dominant II7 (E7#9) in place of the standard half-diminished ii chord, creating a stronger secondary dominant pull toward the A7b9.
  • Features a direct modulation to the submediant (Bb Major) via a standard ii-V-I progression (Cm7 - F7 - Bbmaj7).
  • Employs chromatic dominant substitutions (Db7) to facilitate smooth voice leading and bridge the gap between disparate tonal centers.
  1. Improvisation Focus: The Altered Scale (Super Locrian) for navigating dominant chords to highlight b9 and #9 tensions before resolving to D minor.

  2. Difficulty Rating: 3/5: While the tempo is often brisk, the harmonic shifts are logical, requiring intermediate-level knowledge of minor-key functional harmony and modulation.
