Vocal Range Finder

The test takes about two minutes. You sing one low note and one high note, and the tool does the rest.

1. 01

   Allow microphone access

   Press Start microphone and accept the browser prompt. Nothing is recorded or uploaded; the pitch is read live on your device.

2. 02

   Sing your lowest comfortable note

   Slide down to a low note that still has a clear tone and hold it. When the stability bar fills (about 1.5 seconds), press "Use low note".

3. 03

   Sing your highest comfortable note

   Do the same at the top: hold a high note you could use in a song, then press "Use high note".

4. 04

   Read your range

   The tool shows your lowest note, highest note, and span in octaves, and lights up the range on a reference keyboard. Press Play my range to hear both ends.

Tips for a reliable result

• Warm up first. Five minutes of humming or lip trills will usually add a note or two at each end.
• Use one vowel."Ah" or "oo" gives the steadiest reading. Words make the pitch wobble.
• Keep the volume steady. Sing at a normal speaking-to-singing level. Very quiet notes may not register, and pushing for volume makes the pitch less steady.
• Watch the pitch line. The trace under the note display shows whether you are holding steady or sliding around.

Reliable notes vs extremes

Your extremes are the lowest growl and highest squeak you can produce once. Your reliable notes are the ones you can hit any day, at a normal volume, with a sound you would put in a song. The vocal range finder asks for reliable notes on purpose: those are the ones that decide which key a song should be in.

Comfortable range vs total range

Most untrained singers have a comfortable range of roughly an octave and a half, and a total range of two octaves or more. Melodies in pop and worship songs usually span about an octave to an octave and a half. If a song's melody fits inside your comfortable range, you can sing it for a whole set without tiring.

How voice types are assigned

Classical voice types are defined by range, by tessitura (where the voice sits most comfortably), and by tone colour. The tool shows your notes rather than assigning a label, because range alone can mislead. Use the table below as a guide: find the row whose range best overlaps your result.

Note names use scientific pitch notation: C4 is middle C, and C3 is one octave below it. A result of A2 to G4 fits the baritone row. A result of G3 to D5 fits the alto row and overlaps mezzo-soprano, which is common.

Choosing songs that fit their range

Compare your range with a song's lowest and highest melody notes. If both fit with a note or two to spare, the song is in a good key for you. If the chorus goes above your top note, the song needs a lower key.

Deciding when to transpose

When a song sits too high or too low, count how many semitones it is off, then move it by that amount in the chord transposer. Guitarists can then pick a capo fret so they keep easy chord shapes.

Tracking progress over time

Test once a week at the same time of day, after the same warm-up, and write the results down. Steady practice tends to add a few reliable notes at the top over a few months. Day-to-day changes of a note or two are just normal variation.

Use a slow metronome pulse to keep the timing of your comfortable warm-up patterns consistent between sessions.
