Harmonic Highlights

  • Sophisticated use of Cm7/F and Dm7/F over a static F bass, creating Fsus7-like tension over the V chord.
  • A striking chromatic descent of highly altered dominant 7th chords (D7#9#11, Db7#9#11, C7#9#11) creates intense harmonic movement.
  • Frequent primary V-I cadences feature heavily altered F7 chords (F7#9#11, F7#5#9), adding significant color and tension to the resolution.
  • Standard ii-V-I sequences (e.g., Dm7-G7, Fm7-Bb7-Eb6) are integrated, indicating temporary modulations and secondary dominant functions.

Improvisation Focus Altered Scale (Super Locrian).

Difficulty Rating 5 (Advanced) - The pervasive use of complex altered dominant voicings and chromatic movements demands sophisticated harmonic understanding and improvisational agility.
