The study of particles moving to reveal the resonant structures of a plate at different frequencies. It’s an interesting field, and searching for it in youtube, I can watch many of the videos over and over because they are mesmerizing.

Nigel Stanford apparently took notice of this and he created a music video that is mesmerizing involving a number of different physical phenomenon. I highly recommend you watch the video. It’s a study of what you can do by taking something that is mesmerizing (Cymatics in the field of science) and applying it to another field, in this case music.
