Vocal range test and pitch detector

Note

The nearest note to the pitch you're singing, named with its octave. Middle C is C4.

Frequency

How many times per second the sound wave repeats, in hertz. A4, the A above middle C, is 440 Hz.

Sharp and flat

How far you are from the exact note, in cents. A semitone is 100 cents. Within 5 cents reads as in tune.

Range

Your lowest and highest held notes. A note only counts once you hold it for about half a second, so a slip or a crack doesn't stretch your range.

Common questions

How do I find my vocal range?

Choose Vocal range test, allow the microphone, then sing or hum your lowest comfortable note and hold it for about half a second. Do the same with your highest note without straining. The test shows the two notes, how far apart they are, and the closest voice type.

What voice type am I?

The test compares the middle of your range with six common voice types: bass, baritone, tenor, alto, mezzo-soprano and soprano. It's a rough guide. Singing teachers also listen to the tone of your voice and where it feels most comfortable, and your range grows with warm-up and practice.

What are the vocal ranges for each voice type?

The ranges usually quoted for choir singers are: bass E2 to E4, baritone A2 to A4, tenor C3 to C5, alto F3 to F5, mezzo-soprano A3 to A5, and soprano C4 to C6. Many singers reach beyond these, and the types overlap a lot.

How does the pitch detector work?

It listens to your microphone in the browser and looks for the repeating pattern in the sound wave. The length of one repeat gives the frequency in hertz, which is converted to the nearest note with A4 tuned to 440 Hz. It shows how many cents sharp or flat you are, where 100 cents is one semitone.

Why does the pitch detector show nothing or jump around?

It needs one clear note at a time. Speech, chords, a breathy or whispered voice, and loud background noise don't have a single steady pitch, so the detector waits rather than guess. Sing or hum a steady vowel such as ah, a little closer to the microphone.

Is my voice recorded or uploaded?

No. The sound is analyzed in your browser and never leaves your device, and nothing is recorded. The microphone turns off when you press Stop or leave the page.

Can I use it to tune an instrument?

Yes, for instruments that play one note at a time, such as a guitar string, violin, flute or your voice. Play a single note and watch the cents reading: In tune means you are within 5 cents of the note.
