Make a useful estimate
- Choose a clear, steady passage in the music you are hearing.
- Tap the button on each beat. On a keyboard, focus the button and press Space.
- Keep tapping for 8–16 beats. If you miss a beat, start again.
- If the number seems twice or half what you expected, tap a different pulse: music can support more than one counting level.
Why four taps are a start

What this is not
This is a manual tempo estimate, not automatic audio analysis. No microphone is used and no sound file is uploaded. A changing tempo needs a new measurement; a number does not describe a song’s mood, key or genre.
