A free vocal range test that runs on your device
This vocal range test listens while you sing from your lowest note to your highest and shows the result as note names (A2, E4…), frequencies, the span in octaves and semitones, and the typical voice type your range is closest to — bass, baritone, tenor, contralto, mezzo-soprano or soprano.
Pitch detection runs in your browser: microphone frames are analysed and thrown away, never recorded or uploaded. No microphone, or singing in a noisy room? Use the by-ear mode: play reference notes one at a time and mark the lowest and highest you can sing comfortably.
How to use the Vocal Range Test
- Warm up for a minute with gentle humming or lip trills.
- Press Start microphone and allow access. Sit about an arm’s length from the microphone.
- Sing “ah” on your lowest comfortable note and hold it for a second; then do the same on your highest. The note name appears as you sing and the range bar grows.
- Read Lowest note, Highest note, Range and Closest voice type, and compare your bar with the typical ranges below it.
- Without a microphone, step through notes with the arrows or the keyboard, press Play note, and mark This is my lowest and This is my highest.
Vocal Range Test features
On-device pitch detection
The YIN algorithm finds the fundamental of your voice about 25 times a second, from about 60 Hz to 1,200 Hz (B1 to D6), to within a few cents on a steady tone.
Only sustained notes count
A note joins your range after you hold it within about half a semitone for 0.4 seconds, so cracks, breaths and background noises are ignored.
Voice type comparison
Your lowest and highest notes are compared with six typical ranges, the closest is highlighted, and the table shows how much of each range you cover.
By-ear mode
Reference notes from C2 to C6, played with Web Audio only when you press a button, for marking your range without a microphone.
Live note display
A big note name with frequency and cents, a marker on the range chart and the matching key lit on the keyboard.
Typical voice-type ranges
These are the ranges given for classical voice types by James McKinney, The Diagnosis and Correction of Vocal Faults (1994), and for bass by Richard Boldrey, Guide to Operatic Roles and Arias (1994), as summarised in the Wikipedia article “Voice type” (checked 19 October 2026). Notes use scientific pitch, where C4 is middle C. Choir parts are often narrower, and pop singers are not classified this way at all.
| Voice type | Typical range | Frequency |
|---|---|---|
| Soprano | C4–C6 | 262–1,047 Hz |
| Mezzo-soprano | A3–A5 | 220–880 Hz |
| Contralto (alto) | F3–F5 | 175–698 Hz |
| Tenor | C3–C5 | 131–523 Hz |
| Baritone | A2–A4 | 110–440 Hz |
| Bass | E2–E4 | 82–330 Hz |
What a range test can and cannot tell you
Range is only one clue. Teachers also listen to tessitura (where your voice is most comfortable for long stretches), timbre (how heavy or bright it sounds) and where your voice changes register. A baritone and a tenor can share most notes; the tenor is usually more at ease near the top. So read “closest voice type” as a starting point, not a verdict, and expect your range to grow a few notes with practice and warm-up.
Sing only what feels easy. Never push or shout for an extra note — if singing hurts, or hoarseness lasts more than a couple of weeks, stop and see a doctor or a speech-language therapist.
How the pitch detection works
Each frame of about 43 ms is compared with delayed copies of itself. The YIN method (de Cheveigné and Kawahara, 2002) normalises that difference, picks the first delay that falls under a threshold, and refines it between samples, which avoids most of the octave jumps simpler detectors make. Frequencies become notes with A4 = 440 Hz: note = 69 + 12 × log₂(f ÷ 440). The selftest feeds the detector computer-generated sine and sawtooth waves at known pitches. To check one note against a steady needle, use the online tuner; to name the notes of a song in Indian notation, try the western notes to sargam converter.
Vocal Range Test FAQ
How do I test my vocal range online?
Press Start microphone, sing your lowest comfortable note and hold it for a second, then your highest. This vocal range test records the lowest and highest notes you sustain and shows your range and the closest voice type.
Is this vocal range test free and private?
Yes. It is free with no sign-up, and the sound is analysed inside your browser and immediately discarded — nothing is recorded or uploaded.
What is a good vocal range?
Most untrained adults can sing about an octave and a half; many trained singers manage two octaves or more. A bigger range is not better in itself — what matters is singing your songs comfortably and in tune.
Why does the test not pick up my low notes?
Laptop and phone microphones are weak below about 100 Hz. Move closer, sing a little louder and hold the note longer, or mark your lowest note by ear.
Does falsetto count?
It counts if you can hold it steadily. Many singers note their chest-voice range and their full range separately, and so can you: test once in chest voice, then again including falsetto.
Am I a tenor or a baritone?
Compare your top: tenors usually reach C5 comfortably and sit higher, while baritones usually top out around A4 and have stronger low notes. The table shows how much of each typical range you cover.
