Pitch matching exercises: hear a note, sing it back
The most basic exercise for singing in tune is also the most effective one: hearing a note and matching it with your voice. A note plays on the piano, you sing it and hold it inside a green band, and you see in real time whether you're sharp or flat. It's the place to start if you feel you sing off-key.
How it works
- Tap Start, allow microphone access and listen to the note.
- Sing it right away on a comfortable vowel and hold it until the bar fills up.
- If you stay inside the band, the note counts as in tune and you move on. If not, you can see which way you drifted and hear the note again.
Notes are picked inside your vocal range. Choose Male or Female voice in Settings and you won't get notes you can't reach.
Levels: tolerance and range
Difficulty sets how close you need to be and how long to hold:
- Easy: ±70 cents. Forgiving, so you can start without frustration.
- Medium: ±40 cents. A bit tighter than the average error of an untrained singer.
- Strict: ±25 cents, close to what a trained ear can tell apart.
Range sets how far apart the notes can be: from 3 neighboring notes up to a fifth, an octave or 10 notes. You can also choose which of the 12 notes are in play.
Tips to learn to sing in tune faster
- Sing as soon as you hear the note. Accuracy drops the longer you wait between hearing and singing.
- Start in the middle of your voice and widen the range little by little. Pushing your extremes doesn't help your pitch.
- Don't stay in a range that's too narrow. A 2025 study found that training across a full octave improved pitch accuracy more than training in a small range.
- Practice little and often. Ten minutes a day beats an hour once a week.
Am I tone deaf, or can I learn?
Most people who sing off-key aren't tone deaf: they hear the difference between notes just fine, but their voice hasn't yet learned to land on the note they imagine. That's trainable by singing and comparing, one note at a time. Once single notes feel easy, move on to intervals.
Frequently asked questions
How long does it take to improve pitch?
It varies, but with daily practice many people notice a difference within a few weeks. Consistency matters more than session length.
Which vowel should I sing?
Whichever feels most comfortable; "ah", "oh" or "oo" usually work well. You can also use "ma" or "mo".
Is my voice recorded?
No. The microphone audio is analyzed inside your browser to detect the note, and it is never recorded or sent to any server.
Is it free?
Yes, and you don't need an account. The free version includes some practice time every day; if you want unlimited practice you can upgrade to c4nta Pro.
