of Nature and Things - de Stronk / the Trunk
Instead of the field proximity capacitive sensing used in the other works of mine, in The Trunk I've used close proximity capacitive sensing. This enables the audience to use the water as a water percussion instrument, inspired on the water percussion performed by native tribes of Brasil. To illustrate this sonically I used samples of the splashing sound of water and divided the samples into two parts. The sounding part of immersion in the water and of the withdrawal from the water. While in the water the first part of the splash sound is fed into a feedback delay line. The feedback line is interrupted when you withdrawal from the water. Subsequently you'll hear the second part of the splash sound. For the design of the ceramic trays, they look a bit like exploded chocolate cakes, I was inspired by the melted geometry by Salvador Dali.
The wooden trunk itself can be used as a percussion instrument. Therefor, on the bottom side of the Trunk there are three piezo microphones. Their signals are fed into three separated resonating filter banks that attenuate the spectrum of the wood in three registers. A high tone spectrum, a low one and a mid range spectrum. The base frequency of these filter banks is slightly modulated with a LFO.
