In Nomine Tenebris is something of a “through the looking glass” homage to Scelsi’s late period. The work takes Scelsi’s short organ work In Nomine Lucis (1974) as a “sound object” and subjects it to radical transformation and distortion. The compositional process involved visualising the work as a sonogram, stretching, warping and distorting the image and then resonifying it. The resonification was then visualised a second time and used as the basis of a score for the five acoustic instruments. The final work combines the acoustic instruments and the electronic sonification. The contours of the instrumental parts are used to control spatialisation and audio processing that expands and compresses the acoustic instrumental timbres in a manner analogous to the distortion of the visual image, but in real-time. Like many of Scelsi’s late works, In Nomine Tenebris focuses almost exclusively on timbre and the transitory nature of sonic spectra.
