Vocal range test
Find your vocal range
Sing your lowest steady note, then your highest. The page counts every note you hold for a full second and gives the span in notes and semitones, beside the conventional voice-type ranges.
The range test
The microphone is off. Nothing on this page listens until you press Start microphone.

Your range beside the conventional voice types
Bars: the typical range of each voice type as given by Wikipedia, Voice type. Axis: C2 to D6, the span this page measures.
| Voice type | Typical range | Hz at A4 = 440 | Notes | Your range covers | A second source gives |
|---|---|---|---|---|---|
| Soprano | C4 – C6 | 261.6 – 1046.5 | 25 | — | C4 – G6 |
| Mezzo-soprano | A3 – A5 | 220.0 – 880.0 | 25 | — | A3 – G5 |
| Contralto | F3 – F5 | 174.6 – 698.5 | 25 | — | F3 – C5 |
| Tenor | C3 – C5 | 130.8 – 523.3 | 25 | — | D3 – A4 |
| Baritone | A2 – A4 | 110.0 – 440.0 | 25 | — | B2 – F4 |
| Bass | E2 – E4 | 82.4 – 329.6 | 25 | — | G2 – C4 |
Typical range: Wikipedia, Voice type. A second source: Wikipedia, Vocal range, which gives different approximations for the same six types. Hertz and note counts are computed from the note names.
How the vocal range test works
Start the microphone and sing downwards one note at a time, holding each note for a second, until a note will not hold. Then do the same going up. Every note you hold steadily for one full second is counted. The lowest and the highest counted notes are your range.
Steady has an exact meaning here. The centre of your pitch over the last third of a second has to stay nearest the same note, the swing over that third of a second has to stay under 150 cents, and that has to go on for one second without a gap longer than a quarter of a second. A slide through a note does not count. A note held with vibrato does.
The page cannot tell a sung note from any other steady pitch in the room. If it counts a cough, a hum or a note you would not call singing, press Discard the lowest or Discard the highest. That note is removed and is not counted again until you press Start again.
Reading the result
The range is given in semitones, the distance from one key of a piano to the next. Twelve semitones make an octave (Wikipedia, Cent (music)), so a range of 24 semitones is two octaves and covers 25 notes counting both ends. The frequencies follow your A4 setting.
Voice types are conventions
The bars show the typical ranges that Wikipedia, Voice type gives for 6 voice types. They are conventions from European classical singing, not measurements of anybody, and sources do not agree on them: Wikipedia, Vocal range lists different figures for the same six types, shown in the last column of the table.
The same article says that range on its own does not decide a singer’s voice type, and that where the voice is most comfortable and how it sounds matter more. So this page reports how many notes of each conventional range your measured range covers, and does not name a voice type for you.
What this test does not do
It measures C2 to D6 and cannot count a note below or above that. It measures pitch and not quality: a note counts if it was steady, whether or not it sounded good. It is not an assessment of a voice and not vocal or medical advice.
The range is kept in this browser so that the pitch matching page can offer it. It is not sent anywhere, and Start again removes it. To see the pitch you are on as you sing, go back to the vocal pitch monitor.

How it measures, and what it keeps
The pitch comes from a detector that runs inside this page: the normalised square difference method of McLeod and Wyvill, tuned for a voice from C2 to D6. It was measured on 7,344 synthesised tones, not on recorded singers and not on your microphone; the method page has the tables and says what they do not cover.
The sound from your microphone goes to that detector and nowhere else: it is not recorded, stored or sent. This browser keeps three settings for the trainer’s pages, under labs.sing.a4, labs.sing.solfege and labs.sing.range. The musical facts (note names, cents, scales, intervals, voice types) are read from thirteen published articles, each listed on the method page with its revision and the date it was read.
