Harmonic Highlights:

  • Frequent use of non-diatonic minor chords (e.g., Am7/Am11, Dm11) which are built on the major third and major sixth respectively of the F minor tonic, strongly implying F Dorian mode.
  • Chromatic upper structure on dominant functions, notably Abmaj7#5/Bb, which superimposes Ab Lydian Augmented harmony over a Bb bass pedal.
  • Extensive application of highly altered dominant chords (e.g., Eb7#5#9), providing maximal tension and rich harmonic color before resolutions.

Improvisation Focus: Lydian Chromatic Concept application, especially targeting non-diatonic chord tones and extensions.

Difficulty Rating: 5 (Advanced) - The complex modal shifts, non-diatonic substitutions, and sophisticated altered dominant voicings demand a high level of harmonic understanding and technical proficiency.
