This video is entitled ‘Cymatics,’ and cymatics is the science of creating visualizations of audio frequencies.
On his website, Nigel Stanford, a musician from New Zealand explains how he became interested in visualizing sound:
“In 1999 I watched a documentary on ‘Synesthesia’ – a disorder that effects the audio and visual functions of the brain. People with the disorder hear a sound when they see bright colors, or see a color when they hear various sounds. I don’t have it (I don’t think), but I have always felt that bass frequencies are red, and treble frequencies are white.This got me thinking that it would be cool to make a music video where every time a sound plays, you see a corresponding visual element. Many years later, I saw some videos about Cymatics – the science of visualizing audio frequencies, and the idea for the video was born.”
Cymatics (from Greek: κῦμα “wave”) is the study of visible sound co vibration, a subset of modal phenomena.
