Vocal Range Test - Find Your Lowest & Highest Note
Sing into your microphone to capture your lowest and highest notes, measure your range in octaves and semitones, and see your likely voice type from bass to soprano.
Press Start test, sing your lowest comfortable note and hold it steady, then do the same with your highest. The tester tracks your pitch live, captures each note once you hold it for about half a second, and reports your range, its span, and the closest standard voice type. No microphone? Pick your notes from the two selectors below and get the same result.
Vocal Range Test - Find Your Lowest & Highest Note

You will sing two notes: first your lowest comfortable note, then your highest.

Standard voice types and their ranges
Typical comfortable ranges for the six classical voice types. Trained singers often exceed these; the classifier picks whichever range sits closest to your endpoints.
| Voice type | Typical range | Approximate frequencies |
|---|---|---|
| Bass | E2 – E4 | 82 – 330 Hz |
| Baritone | A2 – A4 | 110 – 440 Hz |
| Tenor | C3 – C5 | 131 – 523 Hz |
| Contralto | F3 – F5 | 175 – 698 Hz |
| Mezzo-soprano | A3 – A5 | 220 – 880 Hz |
| Soprano | C4 – C6 | 262 – 1,047 Hz |
About this vocal range test
Your vocal range is the distance between the lowest and the highest note you can sing with a steady, controlled tone — not a squeak or a growl, but a note you could actually hold in a song. This test measures it directly: the microphone signal is analyzed in your browser with an autocorrelation pitch detector (the same normalized method used in tuning apps), each detection is median-smoothed, and a note is only captured once you hold the same pitch for at least six tenths of a second. That stability rule matters, because scoops, vibrato onsets, and breathy attacks all produce momentary false readings that a naive tester would happily record as your range.
The test runs in two passes. First sing downward to your lowest comfortable note — a relaxed, dark vowel like "ah" works best — and hold it until the display captures it. After a short pause, sing upward to your highest comfortable note and hold that. Falsetto counts if you can sustain it musically, but most classifications are based on the modal (chest and head) voice, so try both and compare. The result shows your range as note names, the exact frequencies, and the span in octaves and semitones; an octave is twelve semitones, and a typical untrained singer spans around one and a half to two octaves.
The voice-type suggestion compares your endpoints against the six standard classical ranges: Bass E2 to E4, Baritone A2 to A4, Tenor C3 to C5, Contralto F3 to F5, Mezzo-soprano A3 to A5, and Soprano C4 to C6. The classifier is a nearest-match: for every type it adds the distance in semitones between your lowest note and that type's lowest note to the distance between your highest note and its highest note, and picks the type with the smallest total; a tie goes to the lower voice type. So a G2 to A4 range lands on Baritone because it misses that range by only two semitones, while it misses Bass and Tenor by eight. Treat the label as a starting point, not a verdict — real classification also weighs where your voice sounds fullest (the tessitura), your comfortable passaggio points, and timbre, which is a job for a voice teacher.
Everything happens locally: the audio never leaves your device, nothing is recorded, and the manual note selectors give the identical calculation when you already know your notes from a piano or cannot use a microphone.
Example ranges and classifications
Sample results and how the nearest-match classifier reads them.
| Sung range | Result | Why |
|---|---|---|
| E2 to E4 | Bass, 2 octaves | Matches the standard bass range exactly — total distance of zero semitones. |
| G2 to A4 | Baritone, 2 octaves 2 semitones | Two semitones from the baritone endpoints, eight from bass and tenor — baritone wins. |
| D3 to F5 | Contralto, 2 octaves 3 semitones | Three semitones from the contralto endpoints in total, seven from tenor — contralto is the closest fit. |
| C4 to C6 | Soprano, 2 octaves | Matches the standard soprano range exactly. |
| A3 to A5 | Mezzo-soprano, 2 octaves | Matches the standard mezzo-soprano range exactly. |
How to test your vocal range
- Warm up for a minute or two first — hum a few scales. Cold vocal cords understate your range and strain more easily.
- Press Start test and allow microphone access. Sing your lowest comfortable note on an open vowel and hold it steady until the tester captures it.
- When prompted, slide up to your highest comfortable note — head voice or sustained falsetto both work — and hold it until it is captured.
- Read your result: the range as note names and frequencies, the span in octaves and semitones, and the nearest standard voice type.
- Repeat a couple of times, or enter notes with the manual selectors to compare — your usable range varies with warm-up, time of day, and technique.
Vocal range test FAQ
How does the test decide my voice type?
By nearest match against the six standard ranges (Bass E2 to E4, Baritone A2 to A4, Tenor C3 to C5, Contralto F3 to F5, Mezzo-soprano A3 to A5, Soprano C4 to C6). It sums, in semitones, how far your lowest note is from each type's lowest and your highest from its highest, and picks the smallest total. It is a useful first estimate, but real voice classification also depends on tessitura and timbre, which need a teacher's ear.
Why does the tester ignore some notes I sing?
A note is only captured after you hold the same pitch steadily for about 0.6 seconds. Scoops, cracks, vibrato onsets, and breathy attacks produce unstable readings that are deliberately discarded, and very quiet singing falls below the noise gate. Sing a clear, sustained vowel at normal volume and the capture is quick.
Should I include falsetto or vocal fry in my range?
Convention says count what you can sustain musically. A controlled, resonant falsetto note is usually accepted at the top, while a whistle-register squeak or a vocal fry rumble at the bottom is normally quoted separately. This tester detects from about C2 up to beyond C6, so extreme fry below that range will not register anyway — test both with and without falsetto and quote whichever is honest for your singing.
What is a normal vocal range?
Most untrained adults manage about 1.5 to 2 octaves comfortably; trained singers commonly reach 2.5 to 3 octaves, and exceptional voices go further. Span matters less than where the voice sits — two singers can both span two octaves yet be a bass and a tenor. Range also grows with technique, so retest after a few months of practice.
The test says Tenor but my choir calls me a Baritone. Which is right?
Both can be. Range endpoints put you near a category boundary, but choirs assign parts by tessitura — where your voice stays comfortable for a whole rehearsal — plus blend and timbre. If your extremes reach tenor territory yet your voice tires above E4, a baritone part is the right call. Use this result as data, not a contract.
Is my singing recorded or sent anywhere?
No. The microphone stream is analyzed frame by frame in your browser with the Web Audio API and discarded immediately — nothing is saved or uploaded, and the page works offline once loaded. The manual note selectors use no microphone at all.
