What Is Soundgo?

Soundgo is a single-page web app that turns a webcam into a musical instrument. Under the hood it uses Google's MediaPipe Hands for real-time fingertip tracking and Tone.js for Web Audio synthesis — both loaded from the jsDelivr CDN, with the tracking running locally in the browser. The result is an instrument you play by moving your hands in the air, with no downloads and no hardware.

The interface shows two circular wheels on the video feed: a chord wheel and a melody wheel. Your fingertips act as cursors over them, and the app draws your hand skeleton on screen so you can see what you are pointing at. The controls cover two modes (Two-hand Chord, Melody + Chord), five scales (Major, Pentatonic, Minor, Blues, Chromatic), four waveforms (Sine, Triangle, Saw, Square), and three octave ranges (2, 3, 4). The code includes thoughtful details: smoothed fingertip positions to avoid misfires, and debounced chord switching so a fingertip resting on a boundary does not flicker between chords.

How to Use Soundgo

1. Open the official Soundgo website.
2. Click "Start" and allow camera access when prompted.
3. Choose a mode: Two-hand Chord or Melody + Chord.
4. Set the scale, waveform, and octave range.
5. Move your hands in front of the webcam — your fingertips hover over the on-screen wheels to play chords and melodies.

Is Soundgo Safe?

What can be verified about Soundgo: it is a static page on gojaehyun.com, the personal domain of developer Go Jaehyun. There is no registration, no third-party login, no payment, and no file upload. The app requires webcam access by design, and the hand tracking is processed client-side in the browser using MediaPipe; the page loads its libraries from the jsDelivr CDN. There are no ads or redirects. The only consideration is the camera permission itself — the app cannot work without it, so grant it only if you are comfortable with webcam use.

Why Is Soundgo Popular?

Soundgo appears to be gaining attention through direct sharing and word-of-mouth, although there is no clear public source showing where the trend originated. The concept is visually striking — playing music with your hands in the air looks like magic on video — and it fits the wave of gesture-based and AI-powered web experiments. As a polished personal project by a developer with a public portfolio, it is also easy to link and recommend.

Soundgo Not Working?

If Soundgo cannot be accessed, try:

1. Refresh the page.
2. Open it in another browser.
3. Allow camera access in the permission prompt — the app cannot work without it.
4. On mobile, rotate to landscape; the app requires landscape orientation.
5. Check whether the sound.gojaehyun.com site is still online.
