Harmonic Highlights:
- The primary ostinato between C7#9 (V7) and Db7#9 (bII7 or chromatic dominant) establishes a dense, chromatically rich minor tonality.
- Frequent use of secondary dominants, such as F7 (V7/iv) and A7b5b9 (V7/vi), enriches the harmonic landscape beyond simple diatonicism.
- Complex ii-V progressions like Dm7-G7sus and Fm7-Bb7 indicate temporary modulations, moving through various tonal centers before returning to F minor.
Improvisation Focus: Altered scales, particularly Phrygian Dominant or Altered scale, are crucial for navigating the prevalent #9 and altered dominant voicings.
Difficulty Rating: 4 (Advanced Intermediate). The constant harmonic movement, altered dominants, and rapid key center shifts require a strong understanding of substitution and modal interchange.
