In preparing devices for performance I have begun thinking of Gilbert Simondon and beginning to realise his influence over many of the phrases used in this sprawling text so far. Initially, thoughts were based around his writing on ‘transduction’ – use of physical transducers on wooden surfaces is part of the development work I am doing on the drone machines. Feeding the audio signal back into the materials that are generating the sound but through physical vibration – this is still sound and can be heard by our ears but exploring a more visceral connection the materials. ‘Transduction is a process where a disparity or a difference is topologically or temporally restructured across some interface. It mediates different organizations of energy.’ (Simondon, Transductions) Don’t want this to merge into interface studies. The use of transducers in the work brings into question all materials at use – it engages them all in sound / noise making practice. All in the aim for stable resonance between emerging sound and parts – as the mathematician Rene Thom stated ‘All interaction rest, in the last analysis, upon a phenomenon of resonance.’ Rene thom has now appeared again in The Birth of Physics by Serres – first encountered him through Deleuze and Guattari.
