Cymatics

The study of visible patterns and shapes created when sound vibrations pass through physical media such as water, sand, or metal plates. Cymatic patterns are deterministic — the same frequency produces the same pattern — creating a predictable visual representation of sound. In accessibility and therapeutic contexts, cymatics-based visualisations have been used to provide real-time audio-visual feedback in music therapy for people with autism, leveraging the predictable cause-and-effect relationship between sound and visual output to strengthen sense of agency and encourage communicative behaviours.
