Painting on Music was my second project “Liquid Art”
I have used a heavy bass-speaker to make short “boom” sound. The sound went to a piece of a ballon on which small paintdrops were placed (sometimes with tiny waterdrops also). The sound makes the ballon tremble by which the paintdrops fly into the air. The drops flew up to 30 cm into the sky (and i just had refurbished our floor in the livingroom …)
I used a Cognisys which registrates sound and after a few milliseconds fires the connected flashes.
It took about 3 days to get the right settings, also because not every paintcolor had the same viscosity. (How thicker the paint, how slower it reacts)
In between every shot, the surface had to be completely cleaned, and new paint and waterdrops to be placed.
