Quadrivium - LEO Melody is activated each time a satellite passes overhead. Each musical instrument corresponds to a specific distance perimeter. Each instrument is associated with a wand that strikes the instrument when the perimeter is crossed by a satellite. The louder the instrument sounds, the smaller the perimeter and therefore the closer the satellite is to us. The drum is activated every time a piece of debris passes through the field of observation encoded in the programme.

The tools sent into space are the instruments that give us a better understanding of living things, at the same time as they are the source of their anxiety and destruction. The aim of this work is to explore the problem of the appropriation of space and its bulimic occupation as a public place: the observation of the earth from space, for the earth and its inhabitants, whatever the reasons and objectives, can only lead to issues of sovereignty and power that seem uncontrollable.

This work highlights, both literally and figuratively, the challenges posed by the growing number of satellites in our orbit, and seeks to reflect on the ambivalence produced by human beings: on the one hand, the extraordinary progress made throughout our history opens up an infinite number of new possibilities, fantasies and ambitions. But on the other hand, as the instruments of observation and knowledge become more complex, more sophisticated and more powerful, human beings seem to see their innate access to observing the sky with their own eyes diminish.

Quadrivium - LEO Melody becomes a trigger for receiving a vision of reality in real time. The aim of this work, and of the sound notes emitted by the various instruments, is to raise awareness of the 'silent' proximity of these satellites, of their increasing number in the Earth's orbit, and of the problems this creates.
