Voice tuner
The voice tuner shows, in real time, the note you are singing (in letters and in solfège), how many cents sharp or flat it is, and the line of your voice over time. The green band covers up to 20 cents; pick a target note on the keyboard and practise until the line turns green.

How to use it
Tap Start, allow the microphone and sing a vowel such as “aah”. The tuner shows the note you are singing, how many cents it is above or below the centre, and the voice line, which draws your pitch over time.
To practise a specific note, tap a key on the keyboard (or pick it in the selector): the note plays for a second and a half and becomes the target. The line turns green when you hit it and orange when you drift. Singing the same note an octave lower also counts — common when a man sings a note written for a female voice.
Without headphones, the microphone ignores the reference while it plays. Look after your voice: warm up first and don’t push the extremes.
Frequently asked questions
How do I know if I’m singing in tune?
Sing a long note and watch the needle and the voice line: within 20 cents either way (the green band) the note sounds in tune. If the line sits below the note you are singing flat; above it, sharp.
Why does the voice tuner allow more error than the instrument tuner?
The voice wavers naturally with vibrato and breathing, and in singing the ear accepts about 20 cents of difference. An instrument needs more precision: the instrument tuner only turns green within 5 cents.
What is the target note for?
For practising a specific note: tap the key, hear the reference and sing. The hint tells you how many semitones are left and which way to go, and the voice line turns green when you reach the note.
Does the microphone record my voice?
No. The sound is analysed on the fly, inside the browser, and is never recorded or sent anywhere.
