Thirteen readings of the same instruction, forty-two minutes long.
Each view of a data cube is quantised into eight brightness bands. The piece steps through those bands while the view itself advances in depth, weighted so that depth carrying more structure takes more time. That instruction never changes here. What changes is the tuning it lands on: struck gamelan bronze, real bell partials where the contrast of a band picks the size of the bell, quarter tones, a raga over a fixed drone, a just-intoned overtone series.
Two sources. A quasar host observed by JWST’s NIRSpec, and a slice of the DESI redshift survey.
Listen for the terraces, and for how differently they arrive when the scale underneath them changes. The next programme is about what those terraces are actually reporting.
