Tropos timbral and temporal qualities are composed in order to acoustically blend within an outdoor soundscape. The strategy adopted here was to work initially with sounds which are plausible1 in this context, and then to explore the boundary between the plausible and implausible. The sonic qualities of Tropos might then recall either natural sounds (crowing, howling, chirping, blowing, etc.) or artificial sounds (motors and other kinds of static noises), which are usually found in an outdoor city context, but with a kind of electronic coloration. In this way, Tropos can sonically blend with a city soundscape while still being recognisable as an aesthetic sound intervention.
1. The term "plausible" refers back to Max Neuhaus and his creation of a permanent public sound work carefully designed to blend with its auditory environment. Max Neuhaus, "Notes on Place and Moment".
