The Desktop Instrument
Built for science enthusiasts, artists, and seekers.
Quantum physics shows that matter is simply a certain vibratory rate of energy. Watch it happen: a mathematically accurate tonoscope that turns any frequency into living Chladni patterns — right in your browser, free.
No download. No signup. Works on your phone.
Every frequency has a shape. Find yours.
Drag the frequency slider and watch the plate reorganize — sand view, color field, or full 3D surface. Explore the ancient Solfeggio tones (396, 417, 528, 639, 741, 852 Hz), OM at 136.1 Hz, piano notes, or any frequency from 1 to 10,000 Hz. Turn on sound to hear the tone you're seeing.

A century of making sound visible.
The study of visible sound and vibration — how frequency organizes matter into geometric form.
Ernst Chladni's 18th-century discovery: sand on a vibrating plate gathers along the silent nodal lines.
The six-tone scale — 396 to 852 Hz — used in sacred music, each with its own distinctive pattern.
The Swiss physician who coined "cymatics" and photographed the hidden geometry of sound.
Quick answers.
A tonoscope makes sound visible: a plate vibrated at a specific frequency organizes a medium like sand into geometric patterns called Chladni figures. Software Tonoscope simulates this mathematically — any frequency, no hardware.
Yes. It runs free in your browser, no download or signup — 1 to 10,000 Hz, twelve color visualizations, sand and 3D views, live tone playback, PNG save.
The Windows desktop version ($35 one-time) doubles the frequency range and adds expanded color visualizations, instrument sound types, deep zoom, expanded plate mediums, and pro export — PSD, TIFF, EPS, RAW and more.
The ancient Solfeggio tones (396, 417, 528, 639, 741, 852 Hz), OM at 136.1 Hz, and 432 Hz are favorites. Every frequency has its own distinctive pattern.
