Harmonic Highlights:
- Frequent deployment of secondary dominants and tritone substitutions (e.g., E7 to Am7, Bb7#11 as sub for E7, Db9 as sub for G7).
- Extensive use of chromaticism and non-diatonic major chords (Fmaj7, Ebmaj7, Abmaj7), creating unexpected harmonic shifts.
- Altered dominant chords (A7#5, D7#11) are common, introducing significant tension and color.
- Ambiguous tonal centers with rapid modulations, demanding harmonic flexibility from the improviser.
Improvisation Focus: Navigating altered dominant harmony through appropriate scale choices and chromatic embellishment.
Difficulty Rating: 5 (Advanced) – The piece features rapid harmonic rhythm, complex chromaticism, and numerous non-diatonic changes requiring sophisticated harmonic understanding.
