Reverb-selected chant

Status: Prior

Status is derived only from the shepherd-authored triage/prediction data above -- community submissions and claims are a separate overlay and can never change it (see the participation panel below).

This is a proposed connection between two domains, generated by a language model. It is not an article and not evidence: it sits below the evidence/publication boundary. A quantitative prediction and a named kill-dataset are attached (when registered) so the claim stays falsifiable rather than merely evocative.

Claim (verbatim)

Reverb-selected chant. Nave RT60 and repertoire co-evolved: long-reverb churches correlate with slower, more melismatic chant and early organum. Falsify: acoustic measurement of Romanesque/Gothic naves vs local repertoire.

Kill-dataset (verbatim)

acoustic measurement of Romanesque/Gothic naves vs local repertoire.

Provenance

Run: Imported conversation (verbatim harvest) · model: claude-fable-5

Origin: operator conversation with Claude Fable 5 at max effort, conducted 2026-07-03, relayed verbatim by the operator into the shepherd session on 2026-07-04. No ModelRun exists for the original generation (it happened outside the pipeline); this transcript file is the canonical capture. Transcript path: docs/generated/conjecture_harvest_fablemax_20260703.md. Model (operator-attested, not pipeline-recorded): claude-fable-5. Novelty disclaimer (verbatim, load-bearing -- rule 4): "Same caveat as before, doubled: at 100 items across all of archaeology and history, some of these will have cousins in the literature I can't check. What I can guarantee is the format — each links two things not normally linked, and each names the dataset or measurement that would kill it."

Novelty / leakage triage

Leaked (already exists in the literature)

An explicit literature exists on the coevolution of reverberant church interiors and chant: acoustic studies argue liturgy adapted to high reverberation (chant replacing speech), that long reverberation constrains tempo and note duration, and that specific spaces (e.g., Cluny) exalted Gregorian chant — substantially the harvest claim including its directionality.

'Why does the acoustic space of churches exalt Gregorian chant?' (ICMC 2005) — Direct acoustic-repertoire study
'Acoustics, Liturgy and Architecture in the Early Christian Church' — Liturgy adapting to reverberation
'Word and Mystery: The Acoustics of Cultural Transmission During the Protestant Reformation' (PMC) — Architecture-liturgy acoustic coevolution frame

Its literature citations feed the frontier as source leads (3 leads below the evidence/publication boundary, not yet reviewed).
