Pitch Accuracy Test

Test how accurately you sing in tune: hear a note, sing it back, and see how many cents you were off. This pitch accuracy test plays 6 notes in your range, scores each one against its target, and shows your average error, your sharp or flat pattern and tips to fix it. It is free and runs in your browser.

Hear lowest and highest

Practice mode shows a live tuning needle while you sing. Leave it off for a fair test.

Use headphones if you can. Then the microphone hears only you, not the tone. If you cannot hear the tone, turn the volume up.

Any octave counts: sing each note where it is comfortable, even an octave lower or higher than the tone.

Finish Step 2 to see how many cents each note was off, your average error and your sharp or flat pattern.

Cents measure pitch: 100 cents = 1 semitone. Each note is scored on its steady part (the first 0.25 s is skipped) against equal temperament with A4 = 440 Hz, in any octave. "Within 25 cents" and the five bands are this tool's own conventions, not a standard. This is a practice tool, not a medical or hearing test.

How to Read Your Pitch Accuracy Result

The big number is your average error: how many cents your sung notes were from the targets, on average. Lower is better. Zero means every note landed exactly on its target. The band next to it puts that number into words.

A cent is one hundredth of a semitone, so 100 cents is the step from one piano key to the next. The line under the number counts how many notes were within 25 cents of the target and turns that into a percentage.

Note by note, each target shows what you sang and how far off it was, as “12 cents sharp” (too high) or “8 cents flat” (too low). The bar marks the offset, and the green zone is plus or minus 25 cents. Press Hear to play the target, then your pitch in the same octave, so you can hear the gap.

The four facts below the notes show your pattern. Overall tendency is your average offset with its sign. Drift is how far your pitch moved from the start to the end of a held note. Wobble is the typical spread of your pitch inside one note.

What Is a Good Pitch Accuracy Score?

An average error of 30 cents or less counts as accurate on this test, and 15 cents or less as very accurate. These five bands are this site’s own convention, not a standard or a grade. The tool shows the thresholds on every result.

Average error	Band	What it means on the test
0 to 15 cents	Very accurate	Notes land very close to the targets
15 to 30 cents	Accurate	Most notes sit inside the 25-cent zone
30 to 50 cents	Fairly accurate	Right notes, often a quarter of a semitone off
50 to 100 cents	Often off target	Misses of up to a semitone
Over 100 cents	Far from the targets	Some notes were a semitone or more away

Compare your runs, not your score with other people. Use the same range and the same room, and watch the average error go down. The tool lists every run in the visit with the change, such as “12 cents closer than your previous run”.

How to Get an Accurate Result

Use headphones, a quiet room and a range that feels easy, and sing each note on a steady “ah”. The test can only score what the microphone hears clearly.

1. Pick an easy range. Press Hear lowest and highest. If either note strains, choose a lower or higher range, or pick your own first note.
2. Wear headphones. Then the microphone hears only your voice. If it picks up the reference tone, the result card says so.
3. Stay quiet for the first second. The tool measures the room noise before the first note.
4. Listen to the whole tone, then sing. Start when the panel says Sing now, and hold the note until the bar is full. The first quarter second of each note is skipped, so a small slide into the note does not count against you.
5. Sing a straight tone. Wide vibrato makes the pitch harder to pin down and shows up as wobble.
6. Keep practice mode off for a real test. The live needle helps you practise, but it also lets you correct each note while you sing.

Sharp, Flat or Drifting: What Your Pattern Means

The tips under your result come from the pattern of your errors, not from a single note. Each one names the numbers it is based on.

• Sharp on most notes: you tend to overshoot. Aim a little lower and settle onto the note.
• Flat on most notes: you tend to undershoot. Use a clear, medium-loud “ah” and aim a little higher.
• Misses in both directions: practise one note at a time. Play it, hum it quietly, then sing it.
• Drift down or up: the note moves while you hold it. Keep the same volume to the end of each note.
• Highest or lowest targets worst: the range is too wide for now. Try the next range down or up.

For exercises that target each pattern, read the guide on how to improve pitch accuracy, then take the test again and compare.

Pitch Accuracy Test, Perfect Pitch Test or Pitch Detector?

This test measures how well you match a note you just heard: pitch matching with your voice. It is a fine-grained pitch test, because it reports cents instead of right or wrong notes.

A perfect pitch test checks whether you can name a note without hearing a reference first. That is a listening skill, not a singing one. A pitch detector shows the note you are singing in real time, with no targets and no score. Use it for free practice, and use this test to measure your progress.

Frequently Asked Questions

How does the pitch accuracy test work?
The tool plays 6 target notes one at a time. After each tone you sing the note back for 3 seconds. The tool measures your pitch on the steady part of each note and compares it with the target in cents.

What is a cent in singing?
A cent is one hundredth of a semitone. There are 100 cents between two neighbouring piano keys and 1,200 cents in an octave. Cents let the test show small misses, such as 12 cents sharp, that a note name would hide.

Is 25 cents off still in tune?
On this test, a note within 25 cents of its target counts as in tune, because 25 cents is a quarter of a semitone. That line is this tool’s convention, not a standard, and the result always shows your exact cents as well.

Can I sing the notes in a lower octave?
Yes. The test ignores the octave, so a target sung an octave lower or higher counts as the same note. The note list marks those notes as octave lower or octave higher, and the cents are measured the same way.

Do I need headphones?
Headphones are best, because the microphone then hears only your voice. Speakers also work. If the microphone picks up the reference tone, the result says so. Your scores stay valid, because each note is measured after its tone stops.

Is my voice recorded or uploaded?
No. The audio is analysed in your browser while you sing, and nothing is uploaded or saved. Your runs stay on screen only while the page is open, so use Copy result to keep a result.

Why does my score change between runs?
Each run is a snapshot. Warm-up, tiredness, the range you pick, room noise and the microphone all move the numbers. Compare runs in the same range and room, and look at the trend over several runs.
