CYMATICS
The image of sound
When you toss a stone at the surface of a pond of water you can see the waves created by he disturbance of he original balance.
In the same way, if you generate a sound at a certain frequency, you can visualize the waves created by its vibration on the surface of a liquid. You are seeing sound!
Lots of experiments were made, inspired by this possibility. One of them is the Rubens tube, we talked about long ago.
Other drawings can be made with powder like salt or in a hard surface, which behaves like swarf in an electromagnetic field.
There are many ways to create cymatic performances. This video, created by Nigel Stanford is very impressive. Not only the visuals are great, so is the music.
Enjoy.
