Fantasy no. 5, from 10 Fantasies for Organ.
For performers: take note of fermati over rests to allow the room acoustic to have the music for a moment. Analyze the score for repeated passages and play them on the same registration. In this way the architecture is delineated for the listener and the re-appearance of a sound event reasserts a contextual awareness. This is music about architecture, symmetry, contradiction, and dialog. Do not rush.
