Free online pitch test: are you singing in tune?
Sing one note into your mic and see instantly whether you are in tune, and how many cents sharp or flat. Free, no sign-up, nothing recorded.
Tap start and sing any comfortable note on an “ah” vowel.
This number is how much of the time your voice stayed within 15 cents of the center of the note. Want to train it every day with exercises that level up?

The test listens through your phone or computer microphone and measures the frequency of the note you are singing, many times per second. It then compares it to the nearest note on the scale and shows the difference in cents.
- 0 cents is the exact center of the note.
- Within 15 cents sharp or flat, most listeners hear the note as in tune.
- Beyond 30 cents it starts to sound off to the people listening.
- 100 cents is one full half step, from C to C#, for example.
After 8 seconds you get a percentage: how much of the time your voice stayed inside the in-tune zone. Holding a steady note is harder than it sounds, which is why this number says a lot about your control.
Getting an accurate result
- Find a quiet spot with no music or TV in the background.
- Hold your phone about 8 inches from your mouth.
- Sing an open vowel like "ah" at roughly speaking volume. No need to belt.
- Pick a comfortable note, not too low and not too high.
- For a harder test, choose a reference note, tap "Hear the note" and try to match it exactly. Any octave counts: men and women can sing the same note at different heights.
What your score means
| Score | What it means |
|---|---|
| 70% or higher | You have solid pitch control. Next step: keep it through melodies, leaps and higher notes. |
| 40% to 69% | The note drifts in and out of center. This is the most common result and improves quickly with a few minutes of daily practice. |
| Under 40% | Your voice is not finding the center of the note yet. This is almost always a coordination skill that has not been trained, not a lack of talent. True tone deafness is rare. |
