Singing in tune is a skill you can train like any other: hear a note, sing it back and get instant feedback on how close you came. This pitch matching game does exactly that. Your browser plays a note inside your vocal range, you sing it back, and as soon as you hold it within the tolerance, the round is yours. The score rewards accuracy in cents and how quickly you find the note.
Everything happens on your device: the microphone is analyzed by the browser itself and no audio is sent to a server. Take the vocal range test first and the game uses your range automatically; or pick low, medium or high.
How to use it
- Tap Turn on microphone and allow access. Wear headphones so the mic doesn't pick up the note being played.
- Pick a level. On easy the notes stay close together and singing in another octave counts; on hard the note name is hidden and the tolerance drops to 20 cents.
- Tap Start. The game plays the note for just over a second and then shows “sing now”.
- Sing the note on “ah” and hold it. The needle shows whether you are sharp or flat; once it stays green for about half a second, the round ends and your points appear.
- Need to hear it again? Tap Hear it again. Can't find the note? Skip moves on to the next one with no points.
- After ten rounds, check your score, your average error in cents and the list of notes. Your best score for each level is saved on your device.
How scoring works
Each round is worth up to 120 points: up to 100 for accuracy (the full 100 within 5 cents, dropping to zero at the level's tolerance limit) and up to 20 for speed (the faster you lock in, the bigger the bonus, down to nothing at six seconds). A perfect game scores 1,200. Your error is the average in cents over the time you held the note, so an off-pitch attack that you correct quickly costs very little.
Why it improves your pitch
Singing off-key is almost always an ear problem, not a throat problem: people don't notice they are a half step flat until someone points it out. Instant visual feedback closes that loop. With a few minutes a day, you start correcting the note on your own, before you even look at the screen. Start on easy, move up to medium once you score over 900, and go to hard when you can hit notes without seeing their names.
Tips
- Sing on “ah” or “oo” with your mouth open: closed vowels and breathy sounds confuse the detector.
- If the note played is out of your reach, change the range; untick “accept any octave” only when you want to train the exact octave.
- Don't push the volume: a steady, medium-loud note is detected better than a shout.
- Play with headphones. Without them, the mic hears the reference note and may score a hit before you even sing.
- Replay hard mode with the automatic range after retaking the vocal range test: your range grows with practice.
Frequently asked questions
Am I tone deaf if I can't match the pitch?
Probably not. True tone deafness (amusia) affects only a few percent of people; most people who think they are tone deaf have simply never had instant feedback on their own voice. That is what this game is for: start on easy, with a 50-cent tolerance and notes close together.
Can kids play this pitch matching game?
Yes. There is no sign-up and no need to read music: on easy and medium the note name is shown only as a reference, and on hard it is hidden on purpose to train the ear alone. Children's voices sit higher, so choose the high range or let the vocal range test set it.
What does “cents off” mean in my score?
A cent is one hundredth of a semitone (half step). “+12 cents” means you were slightly sharp, “−12” slightly flat. The tolerance is 50 cents on easy, 30 on medium and 20 on hard, and the closer you get to zero, the more points you score.
How does the game pick the notes?
With the automatic range, it uses the result of your last vocal range test, saved on your device, and picks random notes inside it. Without a test, it uses the medium range (C3 to G4). You can also choose low (E2 to A3) or high (G3 to E5).
Is my microphone audio recorded?
No. Pitch detection happens inside the browser, on your phone or computer. Nothing is uploaded or recorded; only your best scores and preferences are saved on your device.
Do I need headphones to play?
They are strongly recommended. Without them, the mic can pick up the reference note coming out of the speaker and end the round before you sing. The game only starts listening after the note stops, but headphones remove the problem entirely.
How is this different from the voice tuner?
The voice tuner shows whatever note you sing, freely, for working on a song or holding long notes. The game gives you random notes and scores you, which trains how fast your ear reacts.
