Owing to the style of the piece, the concert was cancelled by the conservatory faculty in defiance of the invitation of leading Dutch composers. The work was subsequently revised in 1996, and it is in this form that it will be performed. The revisions had nothing to do with the conflcts, but rather with refinements to the flow of the musical structure. The alternating figure which propels the movement suggests the opening of the chant, and this figure appears in augmentation about a minute in. Succeeding phrases of the chant are woven into the bass in a kind of cantus firmus at important nodal points in the movement, but the listener is barely aware of its presence.
Some melodic development suggests the contours of inner phrases of the chant.
It serves as an introduction to the Finale as a kind of balance to the Movement I-II set. At the opening of Movement V the chant is heard in its entirety, separated by a portculus chord which is a verticalization of a section of the chant.
