Chladni patterns were discovered by Robert Hook and Ernst Chladni in the 18th and 19th centuries. They found that when they bowed a piece of glass covered in flour, (using an ordinary violin bow), the powder arranged itself in resonant patterns according to places of stillness and vibration. Today, Chladni plates are often electronically driven by tone generators and used in scientific demonstrations. With carefully sung notes and a transducer driving the plate, I'm able to explore the same resonances. Songs are then written based on sequences of patterns and their associated frequencies. An adaptation of this project was developed as a permanent exhibit for the Exploratorium in San Francisco, CA. It debuted in 2013. You can see resources and a history of this project here.
