It changes significantly over its 5 or so hours. He developes small
harmonic motifs throughout, only occasionally revisiting previous ones.
The rhythmic and dynamic material is pretty similar, though. A friend of
mine aptly compared it to a Wagner opera because of its epic proportion
and its use of the small "leitmotives".
