Commentary

Arborescences (Listen)

Arborescences is a stereo acousmatic composition. The sound material derives from particular resonances and timbres produced by striking, rubbing and scraping an assortment of Gamelan instruments. Most of the sonic images in the piece are not recognisable as instrumental sounds because of the extended processing, which focuses on developing particular gestures and textures based on micro elements and groups of partials extracted from the recorded events.

The composition explores temporal syntax based on my research on timescales. Timescales at various points in the piece move at different pace, so that arborescent temporal structures move apart and then meet again. Periodicities turn into erratic behaviour and the opposite, undergoing a number of processes of change at the same time.

Arborescences received a special mention in the Métamorphoses 2008 international acousmatic composition competition, and was presented in various concerts, conferences and festivals around the world, including SMC in Portugal, ICMC in Canada, the Sonoimágenes festival in Argentina, the Sonic Rain concert series in Oregon USA, the international exhibition at the Byte Gallery in Lexington USA, and the ISCM World New Music Days festival in Sydney, Australia.
