Harmonic Highlights
- Prolonged B7sus establishes an initial modal ambiguity, delaying typical dominant resolution.
- Non-functional polychords like Db7/B and Cmaj7/B introduce dense, dissonant harmony over a sustained B pedal point.
- Sharp chromatic descent of dominant 7th chords (B7-Bb7-A7) creates a dramatic and propulsive harmonic sequence.
- Abrupt modulation to the parallel minor (F#7#9 to Bm) is followed by unexpected shifts, demanding agile harmonic reorientation.
Improvisation Focus Navigating non-functional pedal-point harmonies and rapid chromatic dominant cycles.
Difficulty Rating 5 (Advanced) – Requires sophisticated understanding of polychords, modal superimposition, and fluent chromatic voice-leading.
