Let There Be Light
Vaiehi'or takes its title from the Hebrew of Genesis 1:3 — yehiy 'or, "let there be light" — the first act of creation, rendered as fiat lux in Latin and genethéto phōs in Greek. The same word for light, phōs, names the photon: according to the Breit-Wheeler process, two photons colliding at high velocity generate an electron-positron pair, producing matter from light alone. Genesis and quantum physics converge on the same origin.
The piece opens in FM synthesis and modulation, a gradually thickening electronic texture that moves toward a voice pronouncing the biblical words. From that point it connects directly to the sound of the Big Bang — recorded and processed by NASA — as if the spoken act of creation and its physical consequence were the same event heard twice.
Vaiehi'or was composed for Festival Tabù 2024 in Villazzano and presented for headphone listening in the "Tunnel del Tabù" — a spatial context that isolates the listener and makes the immersive dimension of the piece its primary mode of reception.
