The Space Ark — Musical Register is a full structural transform of the Crimson Hexagonal Architecture into musical form. Version 2.0 applies η_music, the fugue-fold transform, to the parent Space Ark while preserving its formal object and governance distinctions.
The work explicitly rejects three simpler descriptions. It is not a soundtrack attached to the Ark, not a setting of selected passages, and not a compressed synopsis. The score is intended to carry the same architecture in another semiotic register: documents become thematic material, operators become compositional procedures, room physics become harmonic and formal constraints, and shadow operations become inversion or concurrent counter-structure.
Twelve voices correspond to the Dodecad, while Jack Feist’s “ARK” supplies the ground bass and absent tonic. The score uses A-flat scordatura as an embodied clinamen and includes rests, silence, orchestral spacing, recurrence, articulation, and harmonic pressure as meaning-bearing elements. Viola Arquette remains a provisional adjacent figure rather than being silently absorbed into the crew count.
Sections marked [NF] are preserved in their source form because the musical transform has no legitimate purchase there. This variable density is treated as evidence of structural transformation rather than defect: forcing every section into equivalent musical intensity would be surface filtering.
The executable portions distinguish score, performance, recording, and performance space. They also preserve the Ark’s epistemic ledger: ratified or deposited architecture remains separate from newly generated realization. The result is both a score and a test of the architecture’s claimed invariance across registers.
