# Vocal Range Test

Record your lowest comfortable note, then your highest. The vocal range test names both notes, reports the span in semitones and octaves, and measures what you actually sang in this session.

## A vocal range test that measures what you sing

A range is not a fixed property of a voice: it moves with warm-up, with the time of day and with the song. Rather than ask you to type a comfortable low and high, the vocal range test listens to two takes and reads the pitches it actually heard.

### Two takes, low then high

Record your lowest comfortable note, then your highest. Each take listens for four seconds and keeps the pitch it heard.

### The span in semitones

The notes are compared as equal-tempered pitches, so the vocal range test reports the distance between them in semitones and in octaves.

### Glitches trimmed away

The extreme tenth of each take is discarded before the result is read, so one crack, click or chair creak cannot define your range.

## Measure a range in two takes

### Record the low end

Start the first take and sing your lowest comfortable note, holding it steady. The take finalizes itself after four seconds, or as soon as you stop it.

### Record the high end

Start the second take and sing your highest comfortable note, without forcing it higher than it wants to go.

### Read the range and reset

The vocal range test names both notes and reports the span. Reset clears both takes so a fresh measurement can start.

## Takes, span and naming

### One low, one high

One take for the lowest comfortable note and one for the highest, each listening on its own.

### 4 seconds

Long enough to settle on a note, short enough that a slide does not dominate the result.

### Semitones and octaves

The span is reported as a semitone count and divided by twelve as octaves to one decimal place.

### 50 Hz to 1500 Hz

The pitch band the vocal range test searches, which covers the common singing registers.

## Who measures a vocal range

### Singers picking a key

Find the low and high ends of what you can comfortably sing before choosing the key of a song.

### Writers casting a part

Check what a session singer delivered on the day rather than what a voice category is supposed to cover.

### Anyone curious about their range

Sing two takes and read the span in semitones and octaves without a teacher or a piano in the room.

## Vocal Range Test FAQ

### What does the vocal range test measure?

The vocal range test measures the lowest and highest pitches you actually sang in two short takes, then reports the distance between them in semitones and octaves. It is a measurement of a session, not a fixed property of a voice.

### How long should I hold each note?

Hold one steady comfortable note for a few seconds in each take. The vocal range test listens for four seconds, then finalizes that take on its own or as soon as you press stop.

### Why is my range different on another day?

A range moves with warm-up, with the time of day and with how tired a voice is, so the vocal range test can reasonably report a wider span on one day than on another. Compare takes from the same session rather than across weeks.

### What are the limits of the vocal range test?

The vocal range test needs microphone permission and a quiet room, and it hears one note at a time, so it cannot score a song. Its search band runs from 50 Hz to 1500 Hz, it names equal-tempered pitches with A4 at 440 Hz, and it measures the takes you sang rather than the full range a voice might reach.

### Does the vocal range test tell me my voice type?

No. The vocal range test reports the notes and the span you sang, and it does not assign a soprano, alto, tenor or bass label, because those categories depend on timbre and training as well as range and a four-second take cannot decide them.

### Does the vocal range test keep the recordings?

No. The vocal range test reads the microphone in the browser and keeps only the pitch it detects from each take; the audio itself is not recorded, uploaded or saved, and the detected notes are discarded on reset.

### How many credits does Vocal Range Test use?

Vocal Range Test runs in the browser and draws zero credits.
