The project incorporates sound ecology and bioacoustic music. The first involves a sound environment that is almost non-existent for humans because we often cannot hear it, while the second allows us to explore the possibility of composing bioacoustic music with sounds that are both audible and inaudible to humans. This kind of composition consists of humanly audible nocturnal sounds combined with bat sounds in the ultrasonic spectrum, suitably processed and shifted into a frequency range that we can perceive. This sound event will be set in the area around the Rihemberk castle above Brnik.
