This voice tuner shows, as you sing, which note is coming out, how many cents it sits above or below the center and whether you are holding it steady. Play a guide note, sing along and keep your pitch line in the green band: a vocal pitch monitor for practicing on your own, warming up before choir or worship team rehearsal, or finding out where you tend to drift.
It is not Auto-Tune: nothing is corrected, recorded or uploaded. Your microphone is analyzed inside the browser, with no sign-up and no app to install.
How to use it
- Tap Turn on microphone, allow access and sing a comfortable note.
- Pick a Guide note, tap Play guide and sing along. Wear headphones, or the mic will pick up the guide.
- Needle centered and green dots on the pitch line: in tune. Yellow is close, red is off; the hint under the needle says whether to go up or down.
- Change the guide with −1/+1 (one semitone) and −8ve/+8ve (one octave), or tap use the note I'm singing.
- Guide too high or too low? Leave accept other octave checked and sing the same note an octave lower or higher.
What cents mean for singers
Each semitone, or half step, such as C to C♯, is 100 cents. Up to about 25 cents off, a note sounds in tune to almost everyone, so the needle stays green up to ±25, turns yellow up to ±50 and red beyond that. Negative means flat, positive means sharp. It is common to go flat at the end of phrases and sharp on high notes sung with force.
Stability and sustain
Stability is the share of the last two seconds in which your pitch moved less than 30 cents; above 70% is a steady voice. Sustain counts the seconds in a row you stay within 25 cents of the note (or of the guide), and best sustain keeps your record for the session. Session range shows the lowest and highest notes you sang steadily.
A 5-minute daily routine
1 min: set the guide to a comfortable note and hold it for 5 seconds with the needle still; repeat. 2 min: raise the guide with +1, one semitone at a time, landing on each note without sliding into it. 1 min: stop the guide, sing the note from memory and only then check. 1 min: on a slightly higher note, try to beat your best sustain without straining. Five minutes every day beats an hour on the weekend.
Tips
- Stay about 8 inches (20 cm) from the mic, away from fans and TV: noise makes the reading jump.
- Practice on open vowels (“ah”, “oh”), which the detector reads best.
- Start in your speaking range. To find out how far your voice goes, take the vocal range test.
- With vibrato the needle swings around the center: what counts is the middle of the swing.
- Sing first, listen, and only then look at the screen. The goal is to hit the note without the tuner.
Frequently asked questions
How can I tell if I'm singing in tune?
Sing a note and watch the needle: green, within ±25 cents, means in tune. Better still, play a guide note and match it; the dots on the pitch line show whether you land on it, scoop up to it or drift away.
What is a vocal pitch monitor?
A tool that draws the pitch of your voice over time, so you can see every note, slide and wobble as you sing. This page combines one with a tuner needle and guide notes, right in the browser.
Why does my pitch line wobble?
A gentle, regular wave is vibrato, which is normal: aim for the middle of it. An irregular wobble usually comes from running out of breath, tension or a note at the edge of your range. Background noise can also make the line jump.
Can a tuner help me stop singing flat?
Yes. Singing flat is rarely a lack of talent: usually you can't hear yourself well, the song sits outside your range, you run out of air or you tense up on high notes. Practicing against a guide note trains your ear to compare and correct; at 5 to 10 minutes a day, most people notice a difference within a month.
Is a voice tuner the same as Auto-Tune?
No. Auto-Tune and other vocal tuner plugins correct a recording; this tuner only shows your note so you can practice. Your voice is never recorded, changed or uploaded.
Can I use it with headphones or earbuds?
Yes, and you should whenever the guide is playing: otherwise the mic hears the guide mixed with your voice. Wired is ideal; Bluetooth adds delay but works for long notes.
Do I need perfect pitch?
No. Singing in tune relies on relative pitch, comparing your voice with a reference, and that is exactly what the guide note trains, whether you sing in a choir, at church or at karaoke.
