Perhaps the most important and possibly the least interesting aspect of electroacoustic composition is the provenance of sound sources. They're obviously important because without them you don't have any raw material but if too much is made about them they become fetishised and the work becomes about the objects or recordings and not about the eventual abstractions, modifications and transformations that produce make the eventual music, the latter being difficult to talk or write about (unlike the sources) or to generate images and other media that people might understand. But a photograph has its own value so here are some of the sound sources that have occupied me for the last few months, day after day, week after week (did I mention slow?).
Exciting? No. Apart from the frame drums and bristly toothbrushes which make a nice photo, the welding machine and oven are somewhat mundane. One could of course contextualise the interest in machines as a concern with the ethnography of technology but in all honesty I'm not in the least concerned with that here. At the time I heard and recorded these sounds I simply found them interesting and worthy of further examination.
Played well the frame drums or duffs are fine instruments but in my work I spend most of my initial preparations trying to eke out, often unconventionally, specific sounds for further treatment in this case the sounds of the skin being activated by wire brushes. Each duff has its own unique set of inner morphologies or sound-shapes determined by size, shape, mass and materials. The wire brushes tease out the sounds I wanted very well, offering shapes that ranged from the percussive to the quasi-melodic/harmonic as some of the activations released a rising harmonic series. The sounds of welding (in this project carried out by an actual welder) is somewhat predictable but there are all manner of subtleties as the metals and rods expand and contract, punctuated by near silences and the soft hiss of gases being released as the heat builds up.
So much for the initial recordings and I'll come to the oven sounds later but my last word on this first stage is that there is no rule that I've managed to set which determines how much time I should spend on this or that sound, then on the combinations, before it becomes evident that something isn't working as well as I thought it would. I therefore work slowly. My next activity involves two processes, both carried out in the digital domain, these being timestretching and filtering (or equalising) the recordings. That phase will form the subject of my next post on composition. Thanks for visiting.
