The sculpture features hemispherical caps in painted fiberglass and a central section in durmast oak wood, crafted according to the golden ratio and mounted on a stainless steel base. Reminiscent of both industrial and organic forms, this archetypal and minimalist object encloses an internal void, hidden from the observer’s view. The sculpture thus acts as a membrane between a visible exterior and a mysterious interior.
As a form of abstract self-portrait, the concept of this sound sculpture draws from a fragment by the Portuguese poet Fernando Pessoa in The Book of Disquiet: “My soul is a hidden orchestra. […] I only know myself as a symphony”.
The energy of the acoustic vibration from an internal loudspeaker activates the sculpture, reproducing fragments of nine symphonic movements. These movements were specifically selected to match the sculpture’s unique acoustic properties. Consequently, the inner space of the work resonates, partially revealing its interiority to the outside world as the sound of a “mysterious orchestra.”
