Harmonic Highlights:
- Alternating tonicizations between F minor (Fm/maj7) and its relative major (Abmaj7) and subtonic major (Dbmaj7) via ii-V-I progressions.
- Prominent use of the Fm/maj7 chord establishing a poignant minor tonic, a Mingus signature.
- Frequent application of altered dominant 7th chords (e.g., C7b13, C7#9, Eb7b13) and tritone substitutions (Db7sus) for chromatic tension.
- Unconventional chromatic dominant shifts (e.g., B13-Bb7) introducing momentary harmonic ambiguity and unexpected turns.
Improvisation Focus: Navigating frequent temporary tonicizations and complex altered dominant harmonies.
Difficulty Rating: 4 (Advanced). The rapid, non-diatonic harmonic shifts, specific minor-major voicings, and numerous altered chords demand sophisticated melodic and harmonic understanding.
