Stellated octahedron

The sculptural object shown is actually a sound object.

The geometric figure is pure, in solid wood and free of any technological device;

Vibrant, it transmits sound in a unique way thanks to its physical and geometric characteristics.

Silent when taken individually, it starts to resonate once in contact with a source of vibration transmitted by the pedestal. In the latter is inserted the technological device useful to play music from devices, via bluetooth, cable or wi-fi. The base, without the structure, would lose its amplification and you could hear sounds at low volume (like those of a turntable not connected to the installation). The effect is that of the tuning fork, whose sound is amplified by the surface (or structure) on which it rests. 


The choice of a harmonic geometry (and not random) as a means of diffusion takes place to better study and observe how the geometry of the sound frequencies interacts with the geometry of the form. Specifically it is a structure studied and used in art and mathematics for its harmonic properties. From Kepler, to Leonardo da Vinci to Luca Paccioli and more recently to Escher. The choice is due to its autodual and multiple geometric (and sonic) properties that enclose more harmonic polyhedra in one, allowing the sound to find numerous geometries with which to dialogue. The solid offers different geometric interpretations depending on the point of view, it can be an octangula star, an increased octahedron, two tetrahedra intersected in their center of gravity, or a cube whose faces are X’s. Visually it is necessary to change perspective to appreciate its characteristics, an exercise that also serves to reinterpret the sound through this type of fruition.

The structure resonates with any music and sound giving its own spatial interpretation. Each frequency, taken individually, is static at the point of greatest resonance of the structure. The set of frequencies that make up a music are in motion with the variation of the music. Spatialization results in a natural effect and expression of the physical phenomenon. The project does not consist in imposing a sound spatialization, but in discovering how this happens as a phenomenon with the variation of the investigated form and matter.
