Chrome Music Lab
musiclab.chromeexperiments.com
A collection of browser-based experiments from Google that make music creation and sound visualization accessible through interactive visual tools.
Why it is useful
Each experiment teaches something real about music theory or acoustics through direct interaction — the spectrogram shows you what sound looks like, the arpeggio builder makes music theory tangible, and the shared piano lets multiple people play together over a URL. Designed to be accessible for children but genuinely interesting to adults. Works on any modern browser, no account needed.
