# Moshe's Digital Instruments > Five real instruments, synthesized live in your browser — a steelpan, a theremin, a kalimba, a glass harp and a lever harp. No samples, no installs, fifteen songs with a follow-along guide. Everything runs in the browser with the Web Audio API: free, no sign-up, no downloads. Each song page loads the instrument with the song ready, offers Listen and Play along (the next note lights up until you play it), and prints every note in the instrument's own notation. All songs are public domain or traditional. ## Instruments - [Steelpan](https://moshejs.github.io/digital-instruments/steelpan/): Play a Caribbean steel drum in your browser. 25 hammered chrome note pads in the authentic circle-of-fifths layout, synthesized live with Web Audio, plus fifteen songs with a follow-the-lights play-along guide. - [Aetherwave — Theremin](https://moshejs.github.io/digital-instruments/theremin/): Play a theremin in your browser: glide your cursor for pitch and volume, or tilt and shake your phone.
