Am I a mezzo-soprano? Sing two notes and see.
Mezzo-soprano sits between the two labels most singers are handed, and it is where a large share of adult female voices actually belong. This page measures both ends of your voice, names them, and shows how much of the A3 to A5 span you cover. It runs in the tab and nothing is uploaded.
Two sweeps, about a minute each. Your browser will ask for the microphone. The audio is analysed in the page and never sent anywhere.
Step 1 of 2, your lowest note
Your result
One end of your range went past what this page can measure. Below 65 Hz, roughly a C2, the detector stops giving a number it can stand behind, so your real low note is at or below the one shown. It says so rather than printing a guess.
What the microphone actually heard
Low sweep. The dashed line is the note that was kept.
High sweep. The reading is drawn raw, before any octave correction, so you can see what the detector saw.
Open the trainer, level 1 free
Or keep it. This range test and all six levels of the trainer are two files that run with the internet switched off, 9.99 on the store. One price, once, nothing to unlock afterwards. Everything on this page stays free to use here, what you pay for is keeping it.
Same measurement, no type chosen in advance. It names the closest of the six for you.
The type that gets skipped over
Choirs mostly need two female lines, so singers get sorted into soprano or alto and the middle disappears. Mezzo is the type that sorting has no room for, which is why so many people arrive at it late and by elimination, after the soprano part felt permanently high and the alto part felt permanently dull.
The span this page measures against is A3 to A5. It overlaps the soprano range above and the alto range below by most of their length, so expect your reading to touch all three. That is the normal result, not a failed test.
What separates a mezzo-soprano from a soprano
Not the top note, which is the assumption almost everyone starts with. A trained mezzo will often reach the same high notes a soprano does, and a soprano who has never worked on her lower range will measure shorter at the bottom than a mezzo does.
The difference that actually holds up is where the voice is comfortable for a long time, and what it sounds like in the middle. A mezzo tends to have more body and colour in the middle of her range and finds sustained singing at the very top more costly. A soprano is lighter through the middle and gains rather than spends energy as she goes up.
Both of those are qualities of sound rather than frequencies, and a microphone reading in a browser tab cannot see either. That is the honest limit of this measurement, and it is why the page names a closest type instead of handing down a verdict. Compare with the soprano page if your result sits on the boundary.
Why one measurement is not enough
Range is not a constant. It is wider once you are warmed up, noticeably narrower first thing in the morning, and it widens with training, usually at the top and usually slowly. A single sweep taken cold will under-report you at both ends.
Take the test twice, once cold and once after ten minutes of warming up, and the gap between the two readings will tell you more about your voice than either number does alone.
Getting a result you can trust
The test listens for a note you hold. A note that flashes past on the way through is not counted, because a single frame at the end of a sweep is almost always the detector slipping an octave rather than you singing. Hold each end for about three seconds and you will see it lock on.
- Sing an open ah, out loud. Humming is quieter and the low end of a hum is often too breathy to read.
- Start on a note that feels easy, then slide. Do not jump to the extreme, you will strain and the number will be worse.
- At the bottom, stop before it turns into a creak. Vocal fry has almost no pitch in it.
- Quiet room, microphone not too close. A phone at arm's length works fine.
Where the number comes from
The pitch detector is the same one that runs the live monitor and the trainer. It is a YIN detector with a correction pass, and it used to read every note sharp, by 2.6 cents at a concert A and by nearly 30 at the bottom of a bass range. That failure and its fix are written up with the before and after measurements in my pitch detector read every note sharp. An earlier version of the octave correction folded good readings away one frame at a time, and that one is written up in an octave correction that could not tell a glitch from a soprano.
Nothing is uploaded
The microphone stream is analysed inside the page. There is no server, no account, no upload and no cookie for this test. Close the tab and the whole thing is gone. The only file that ever leaves your machine is the result image, and only when you click the button that makes it.
The other five voice types
Each one has its own page, with the same test and the reference range for that type. Bass, Baritone, Tenor, Alto, Soprano. If you would rather not pick a type first, the general vocal range test measures your voice and names the closest of the six for you, and the vocal range chart shows all six drawn on one axis before you sing a note.
