Play an online theremin in your browser

playtheremin.grok.me

Visit

An online theremin for the browser: hold the pitch field and glide, left to right for pitch and higher for louder. Arrow keys or WASD play it too, and on a phone two fingers split volume and pitch. Pick sine, triangle, saw or square waves, snap to chromatic, pentatonic or major scales, and tune glide, tone, space and volume with knobs. A live scope shows the waveform as you play.

Play solfeggio frequency tones and colors

resonance-atlas.grok.me

Visit

Player for seven solfeggio frequency tones from 174 to 963 Hz as pure sine waves, each shown with its nearest note and chart color. Each tone can be layered over a 440 Hz reference to hear the interval, and a bench covers pi, primes and the golden ratio. The app labels the traditional meanings as contemplative readings rather than science, so it works as a simple frequency tone generator.

Visit

Like a chord progression generator, it copies the chords as text or exports four MIDI loops for a DAW. Built with Grok.
