Resonance
Speaker, 30 x 40 cm Aluminum plate, Black glass powder, Frequency generator, motion detector, Video, Sound

Every material resonates at specific material inherent frequencies, which depend on size, shape and thickness of each material. Ernst Chladni was the first to visualize such frequencies on a flat surface by sprinkling sand on it and striking it with a violin bow. When the plate starts vibrating at the resonant frequencies, the sand will move and form patterns. Today a metal plate and a speaker are producing those visible sound formations. For this piece I replaced the sand with glass powder, which vibrates into the patterns and is then fused a kiln into its solid shapes. The metal plate used in this project has approx. 200 resonant frequencies within the audible range. If the metal plate is vibrated at non- resonant frequency, no patterns will form.
The project was about to visualize vibrations so that what is audible would also become visible. The cloud formation of the glass patterns represent all the tones existing in the particular material used to create them, which in this case was a 30 x 40 cm 1,18 mm thick sheet of Aluminum.
