Pitch Matching Test — can you sing in tune? (mic, cents accuracy)
Hear a note, sing it back, and see how many cents off you are. Eight notes in a lower or higher range, echo or memory mode, a 0–100 score, per-note error and wobble, any octave accepted — all measured in your browser with nothing recorded, plus a shareable challenge with the same notes.
🔒 Runs entirely in your browser. Your input and output are never sent to a server or stored — fully private.
🎤 Uses your microphone only while the test runs. Nothing is recorded or uploaded — the pitch is measured in this browser.
100 cents = 1 semitone. Each note scores 100 minus your error in cents, so 20 cents off scores 80. Any octave counts — sing where it is comfortable. A quiet room and a steady "ah" give the cleanest reading.
About this tool
This pitch matching test checks how accurately you can sing a note you have just heard. Press Start, allow the microphone, and for each of eight notes listen to the tone and then sing it back on a steady "ah". The tool tracks your pitch live on a needle, ignores the first moment while your voice settles, and takes the median of the rest, so you get the error in cents for every note, how much your voice wobbled, and an overall score out of 100. Pick a lower or higher range, choose Echo or the harder Memory mode with two seconds of silence first, and sing in whatever octave suits you. Nothing is recorded or uploaded — the pitch is measured in your browser — and you can share a link that gives a friend the same notes.
Frequently asked questions
What is a cent, and how close is "in tune"?
A cent is one hundredth of a semitone, so 100 cents separate neighbouring piano keys. Differences of roughly 10–20 cents are often noticeable to an attentive listener, especially against a chord, while a quarter tone (50 cents) sounds clearly wrong. Holding sustained notes within about ±20 cents is a solid result; trained singers aim tighter on long notes. Each note here scores 100 minus its error in cents, so the score reads directly as accuracy.
I scored badly — am I tone deaf?
Probably not. True tone deafness — congenital amusia, difficulty hearing pitch differences at all — is estimated to affect only a small percentage of people. Research suggests that many more people who call themselves tone deaf hear pitch differences fine but have trouble steering their voice to the right note, which is a coordination skill that improves with practice. If you can tell which of two notes is higher, try singing slowly with a tuner or this test and focus on matching rather than performing.
Why can I sing the note in a different octave?
Because notes an octave apart share the same name and blend so closely that matching them is the natural thing to do — men routinely sing a melody an octave below women and children. The test folds your pitch into the nearest octave of the target before measuring, so singing an A2 against an A3 counts as exact. Choose the range closest to your speaking voice so the notes stay comfortable; straining at the top or bottom of your range is what usually pulls the pitch off.
How do I get an accurate reading?
Sing a steady open vowel like "ah" at a comfortable, moderate volume, about an arm's length from the microphone, in a quiet room. Hold the note for the whole singing window — the first moment is ignored, and the result is the median of the rest, so a slight scoop at the start or a little vibrato does not hurt. Background music, a fan or a TV can confuse the detector. If a note shows "no voice detected", sing a little louder or move closer.
What is the difference between Echo and Memory mode?
Echo lets you sing straight after the note, while it is still fresh — this measures pitch matching. Memory inserts two seconds of silence first, so you must hold the pitch in your head before singing, which is what choir singers do when they take a starting note from a piano and what you need to sing a melody back accurately. Most people score a little lower in Memory mode; the gap between the two shows how stable your pitch memory is.
