What's puzzling me is the nature of his exotic harmony. The melody is memorable, or at least seems it. It is very modal, and clearly centred on E. The middle section prolongs in the same way that any classical binary movement would (taking to new places, harmonic exhoration, disruption, etc). I think the E is prolonged through harmonic disruptions right from the start. The cadences are more harmonically coercive. What's the difference?
- A coercion is about enforcing a disposition: a regular rhythm, a clear harmony, a repeated motif.
- A disruption suggests extending/enlarging a disposition: A new motif, a strange harmony, an unexpected rhythm.
- An exhortation transforms a disposition: a new key, new theme, new mood
