Put a free metronome on your site
One line of HTML. No signup, no account, no API key, no fees, and nothing to maintain. It works on WordPress, Squarespace, Wix, Ghost, Notion and most LMS platforms — anywhere you can paste an embed code.
This is the actual widget
Not a screenshot. Press play — it's the same thing your visitors will get.
Audio starts only when someone presses play, and stops if the tab is hidden.

Preset it for your lesson
Add parameters to the embed URL so the widget opens ready for whatever you're teaching — a slow practice tempo, a waltz, a dark page.
| Parameter | Values | What it does |
|---|---|---|
bpm | 40–300 | Starting tempo. Defaults to 100. |
sig | 4, 3, 5, 6 | Time signature — 4/4, 3/4, 5/4 or 6/8. Defaults to 4/4. |
theme | light, dark, transparent | Match your page. transparent inherits your own background. |
Example — a 60 BPM waltz on a dark page: /embed?bpm=60&sig=3&theme=dark
What it costs
- Nothing. It's free to use on any site, including a commercial one.
- Keep the credit line. The snippet includes one small text link under the player. That link is the only thing asked in return — it's how people find the rest of the tools. Please don't remove it.
- No tracking of your visitors. No cookies, no analytics beacon, no personal data collected inside the widget.
- No account, ever. There is nothing to sign up for and nothing that can expire.
If the widget ever needs to change in a breaking way, the old URL keeps working. Embeds shouldn't rot.
