How the vocal range test works
The page listens to your voice and works out the note you're singing many times a second. A note only counts towards your range once you've held it steadily for about half a second, so brief cracks, breaths and background noise are ignored. Your lowest and highest steady notes give your range, shown in notes and in octaves (12 semitones make one octave).
Your range is then compared with the usual ranges of the six main voice types. It's a rough guide: trained singers are classed by the tone and comfort of their voice, not just the notes they can reach.
Typical voice ranges
- Soprano: about C4 to C6
- Mezzo-soprano: about A3 to A5
- Alto (contralto): about F3 to F5
- Tenor: about C3 to C5
- Baritone: about A2 to A4
- Bass: about E2 to E4
Most untrained voices cover around one and a half to two octaves. Middle C on a piano is C4.
Getting an accurate result
- Use a quiet room and turn off music, so the test only hears you.
- Sing vowels like "ah" or "oo"; they give a clearer pitch than words or humming with your mouth closed.
- Test at different times. Most voices are lower in the morning and reach higher once warmed up.
Frequently asked questions
Why did it record a note I didn't mean to sing?
A loud, steady background sound can count as a note. Press Reset in a quieter spot and try again.
Can I see the note I'm singing without the range?
Yes, use the pitch detector, which also draws a graph of your pitch.
Is my voice recorded?
No. The sound is analysed live in your browser and is never saved or sent anywhere.
