What is experimental music today? This book offers an up to date survey of this field for anyone with an interest from seasoned practitioners to curious readers This book takes the stance that experimental music is not a limited historical event but is a proliferation of approaches to sound that reveals much about present-day experience An experimental work is not identifiable by its sound alone but by the nature of the questions it poses & its openness to the sounding event Experimentation is a way of working It pushes past that which is known to discover what lies beyond it finding new knowledge forms & relationships or accepting a state of uncertainty For each of these composers & sound artists craft is developed & transformed in response to the questions they bring to their work Scientific perceptual or social phenomena become catalysts in the operation of the work These practices are not presented according to a chronology a set of techniques or social groupings Instead they are organized according to the content areas that are their subjects including resonance harmony objects shapes perception language interaction sites & histories Musical materials may be subject among other treatments to systemization observation examination magnification fragmentation translation or destabilization These restless & exploratory modes of engagement have continued to develop over recent decades expanding the scope of both musical practice & listening
