## Canonical Thesis
"Everything that can be heard has structure. Sonologium makes that structure visible—and audible. The score is not the performance. The recording is not the acoustic event. The waveform is not the listening experience. The sonification is not the underlying scientific phenomenon."

## The Three Intertwined Domains
- 1. Music Domain (Indigo #818cf8): Composition, score notation, physical instruments, organology, genre genealogies, and recording history.
- 2. Sound Domain (Cyan #38bdf8): Physical acoustics, longitudinal pressure waves, environmental soundscapes, marine bioacoustics, and noise profiles.
- 3. Listening Domain (Amber #f59e0b / Rose #f43f5e): Biological audition, cochlear tonotopy, psychoacoustic thresholds, CDC audiometry, accessibility mix, and data sonification.

## Authoritative Corpora Backbone
- Library of Congress National Jukebox: Pre-1925 historical public-domain recordings, matrices, acoustic signal metadata.
- Library of Congress Notated Music: Digitized sheet music, computational musicology, chord vocabulary, and rubato analysis.
- Smithsonian Open Access Collections: Musical instruments connecting Hornbostel-Sachs classes, body geometry, and resonant modes.
- NOAA Passive Acoustic Archive (NCEI): Deep sea underwater hydrophones, marine mammal vocalizations, and vessel cavitation noise.
- National Park Service Natural Sounds: 33 1/3-octave band sound pressure levels, 24-hour diurnal timelines, and the Quiet Atlas.
- NASA Data Sonifications: Multidimensional Chandra, Webb, and Hubble telescope mappings dispelling vacuum sound myths.
- CDC NHANES Pure-Tone Audiometry Surveys: Population hearing thresholds from 250 Hz to 8 kHz anchoring the Accessibility Mix.
