Four minutes of wax per epic

Claim (verbatim)

The first sound archive of Oceania was made in 1898, when the Cambridge Anthropological Expedition to Torres Straits carried a phonograph and wax cylinders to Mer and Mabuiag — over a hundred cylinders, now held in the British Library's sound collections, the earliest field audio of the region. A cylinder holds a few minutes; the repertoire did not. The expedition's own Reports (the music analysed by C. S. Myers) describe ceremonial song series run in sequence through whole nights of performance. So the founding audio record of Pacific orature was cut to the grain of its medium: performances entered the archive as excerpts, long-form genres as fragments or not at all, short genres whole — a truncation systematic enough to masquerade, ever after, as the shape of the repertoire itself. The bias is measurable from inside the collection, because the documentation records what the items were cut from: match the cylinder contents and durations against the Reports' genre descriptions, and the medium's fingerprint — duration ceiling, excerpt marking, genre skew — should stand out against any hypothesis that the recording sampled the repertoire evenly. What the expedition preserved is real and precious; what it silently established is a four-minute unit of record for traditions that did not come in units — the first instance of a sampling grain every later recording technology re-imposed. Prediction: in the digitized Haddon expedition cylinders, over half of the song items will be excerpts of longer performances (cut at the medium's limit or documented in the Reports as portions of series), the median recorded item will run under three minutes, and the genres the Reports describe as multi-hour ceremonial series will appear only in fragment form (primary clause: the over-one-half excerpt share; the verdict follows it). Kill: the Haddon Torres Strait cylinder collection in the British Library sound archive, its catalogue durations and item notes read against the music and ceremony descriptions in the Reports of the Cambridge Anthropological Expedition to Torres Straits (Cambridge, 1901–1935).

Novelty / leakage triage

anticipated in the literature — this exact test has never been run

The 1898 Torres Strait cylinders (British Library) and the expedition Reports with C. S. Myers's music analysis are published, and the physical duration ceiling of a wax cylinder is a known fact of the medium — so the 'median under three minutes' sub-clause is nearly guaranteed. But the primary clause is an excerpt-share census: over half of the recorded song items shown to be excerpts of longer performances by matching cylinder contents and durations against the Reports' genre descriptions. That item-by-item collation was not located as ever having been performed. Materials in print, arithmetic un-run. Adjacent.
