– the latin term to pass through, penetrate, reach – is a set of works
that use changes in local environmental conditions to generate and
structure musical material. Influenced by Brian Eno's ambient music
concept, works of the series all use sensors to poll data from the
surrounding environment and create a soundscape that is unique to the
current locale. Sensors include photoresistors, thermistors, PIR motion
sensors and humidity sensors. Data from these are mapped various
parameters that control rhythmic, melodic, harmonic, timbral, textural
and structural elements of the work.
The first work in the pervado series, quartet
creates ambient music that is structurally controlled by changing
environmental conditions. Data from photoresistors, thermistors and
motion sensors is continually polled to a Pure Data patch, where a
network of intricate mappings is used to control the development and
movement of the music. The project files can be accessed at Bitbucket; they
