echo 1
Along the River Cherwell (at the side of the Botanic Garden) were
placed a
series of bat detectors, each tuned in to the frequencies of the
particular bats that visit in the evening in search of food. As the bats flew past, their
signals were picked up by the bat detectors, and sent to a central
computer hosting a collection of virtual instruments created
in order to respond to the incoming bat calls. These different
instruments took the volume, pitch and bandwidth information
inherent in the different calls to create different voicings in the
music and were then sequenced by a controlling score in order to
shape the composition's harmonic depth and overall form.
The resulting composition took the form of a four-dimensional experience, where
listeners listened to the composition through multiple speakers, experiencing the
different sounds as they moved around the space. As well as this, sections of the bats
flight paths along the river were
illuminated providing a dynamic visual stimulus to the sounds and allowing the audience
to make the connection between the corresponding music and the bat
behaviour.
As I worked on my various sound installations for the Botanic Garden and created the Echo 1 piece I also wrote a blog documenting
some of my process. You can read it here. It is also
possible to listen to an extract of Echo 1 by going to my
Listen page, where you
will also find a short radio review of the work.
