echolocation
history
The idea for Echolocation came whilst working on one such composition: my
gr0w sound installation for the
Hannah Peschar Sculpture Garden. Whilst devising this piece I
experimented with different ways of connecting with the garden's soundscape, including ultrasonic sound, and for which purpose I had
purchased a bat detector. As I sat in the garden one night picking up the bats' biosonar signals, I realised that what I was
holding in my hand was a potential musical instrument, and not only that, but what was being 'played' was the result of a collaboration
between the bats as well as myself.
Later on I developed this idea further with a sound installation proposal for the
London Wetland Centre. This large scale project took the form
of a musical composition for a ‘choir’ of bat detectors, located in optimum positions to receive the ultrasonic calls of the bats that
visit the reserve. These signals are then transmitted to a sound manipulating computer, which in turn records, processes and
sequences the sounds according to an algorithmic composition for an audience to listen to the following day. The proposal was
shortlisted for the 2008 New Music Award.
