Headphones give a cleaner replay.

Uses your microphone to hear your pitch. If the box is ticked, your voice is also recorded into a replay clip, in this browser only. Nothing is uploaded. The clip is gone when you close the page, unless you save or share it.

What this is

A note plays. You sing or hum it back, in any octave, and a lime dot shows how close you are. Hold the dot in the white band for a second to clear the note. Eight notes make a run.

How to use it

  1. Press Start and allow the microphone when your browser asks.
  2. Listen to the note, then sing or hum it in any octave. Move the lime dot into the white band.
  3. Hold the dot inside the band for one second to clear the note. Eight notes make a run.

Questions

Do I need to be a singer?

No. Humming works as well as singing. The game only measures pitch, not tone or style.

Does the octave matter?

No. Only the note name is compared, so sing in whatever octave suits your voice.

Why is my dot jumping?

Usually background noise or a breathy tone. Try humming closer to the microphone in a quiet room.

Is my voice recorded?

Only if you leave "Include my voice in the replay clip" ticked. Then it is recorded in this browser, to make the clip you see at the end. It is not uploaded. It is gone when you close or reload the page, unless you save or share it. The mic is still used to measure pitch if you untick the box.

Does it work on a phone?

It is built for current mobile browsers. Low notes are harder for phone mics, so a low voice may need to hold the phone closer.

What is Do Re Mi?

Two things share those words. In many countries Do Re Mi are simply the names of the notes, with Do always meaning C. In ear training, Do can instead mean the home note of a key, and the other names count steps from it. This page has both: a switch for the note names, and a mode where you sing a step from Do. As note names, the note B is called Si. As steps of a scale, the seventh step is called Ti. They are two systems, so both appear on this page.
