The singing range test listens to your voice through the microphone, estimates the pitch many times a second, turns each stable pitch into a note name, and works out the distance between the lowest and highest notes it accepted. That distance, in semitones and octaves, is your measured range for that session.
It shows what you produced during one test. It does not judge how well you sing, diagnose your voice or give a final voice type. To run it, start on the singing range test on the homepage. For the exact rules of every tool, see Testing Methodology; for what can go wrong, Accuracy & Limitations.
The short version
- You allow microphone access when you start.
- You sing comfortable notes, then move gradually lower and higher.
- The tool estimates the pitch of your voice, ignores readings that are too short, quiet or unstable, and converts the rest to notes.
- It reports your lowest and highest accepted notes and the span between them.
What the test measures, and what it does not
Depending on the mode, a result can include your lowest and highest accepted notes, the semitone and octave span, and educational estimates such as a broad voice type. A frequency becomes a note by calculation; a voice type needs interpretation, and one extreme note cannot decide it.
A range test cannot tell you how good a singer you are. It does not measure vocal health, pain or strain, expression, tone quality, stamina, repertoire suitability, your future range or a definitive classical voice type. Two people can share the same lowest and highest notes and still differ in tessitura, timbre, technique and comfort.
Choose a test mode
The homepage test offers modes for different levels of guidance, currently labelled Quick, Professional and Guided. The live interface is always the source for what a mode does, because the features can change.
- Quick: a fast snapshot of your lowest and highest detected notes.
- Professional: a more structured session. “Professional” describes the mode, not a professional assessment.
- Guided: step-by-step instructions that make sessions easier to repeat. It does not guarantee laboratory accuracy.
How the test works, step by step
1. Allow microphone access
Your browser asks for permission when you start. If you refuse, the tool cannot hear you. If nothing is heard, check the browser permission, your device privacy settings, whether another app is using the microphone, and that the right input is selected. In-app browsers from social apps sometimes block the microphone; open the page in your normal browser instead.
2. Start with comfortable notes
Begin where singing is easy. You do not need to start at the very bottom or top, and starting gently helps you avoid forcing extremes.
3. Explore lower and higher
As you move down or up, the tool looks for pitches that are steady enough to count. Very brief, noisy or unstable readings may be left out, depending on the filtering in the tool you are using. Aim for clear, sustainable notes, not the widest possible number, and stop if a note hurts.
4. Pitch becomes a note
Pitch detectors estimate a frequency in hertz, then convert it to the nearest note with A4 = 440 Hz as the reference: about 261.63 Hz is C4, 440 Hz is A4 and about 880 Hz is A5. The formula and the detection methods of each specialised tool are on the methodology page.
5. The range is calculated
One octave is 12 semitones. Lowest note C3 and highest note C5 is 24 semitones, which is 2 octaves. That is the measured span between the two accepted notes.
6. Results and estimates are shown
The result screen can mix calculations (notes, span) with estimates (voice type). Treat the estimates with more caution than the calculations.
How to read a result
Suppose your lowest accepted note is A2 and your highest is A4: that is 24 semitones, or 2 octaves. It means the test accepted pitches across two octaves in that session. It does not mean every note between is comfortable, that A4 is sustainable in a song, or that your voice type follows from those two notes alone.
Which tool answers which question
The homepage test answers “what is my range?”. Ten other tools each answer a narrower question, and each states its rules, limits and privacy behaviour on the methodology page.
| If you want to know… | Use | You get |
|---|---|---|
| How in tune you are | Pitch Accuracy Test | A score out of 100 and your average error in cents on target notes. |
| A quick grade for a short take | Singing Grader | A 1 to 10 grade with the formula shown. It does not judge rhythm or tone. |
| How high you can sing on demand | the top-note climb | The highest target you hold for one second, up to C7. |
| The pitch of your speaking or singing voice | Voice Frequency Test | Median pitch in Hz, nearest note, and variation. |
| Which note you are singing right now | the live note readout | Note, Hz and cents live, plus a log of held notes. |
| Your voice type | the three-note voice type estimate | A closest match from your lowest, highest and easiest notes, with a chart. An estimate, not a classification. |
| The notes in a phrase or recording | Note Finder | Notes in order on a staff and keyboard, from the microphone or an audio file. |
| How steady and clear one vowel is | Voice Quality Test | Separate readouts, no score, no health claims. |
| Which scale you are singing in | the scale-matching tool | The best-fitting of 72 scales for the notes you hold. |
| What your recording sounds like shifted | Vocal Pitch Changer | Your take moved up or down and saved as WAV or MP3. |

| Detected pitch | Estimated from the microphone signal |
| Musical note, semitone and octave span | Calculated from the detected frequency |
| Lowest and highest note | Taken from the pitches the tool accepted |
| Voice type, comfortable zone | Estimate from fixed rules; educational only |
| Register or passaggio notes | Reference text; not detected from your audio |
How accurate is it?
We do not publish an accuracy percentage. The specialised tools were tested with generated signals and simulated browsers, not with real voices, real microphones, Safari, Firefox or phones, and the homepage test has not had that review. Microphone processing, background noise, unstable pitch and your voice on the day all change results; use the same device and conditions when you compare sessions. The details are on Accuracy & Limitations.
If a result looks wrong
- A note looks far too high or low: repeat it; a harmonic, background sound or an octave error is likely.
- The range looks too narrow: check that the microphone hears you, sing steady notes, reduce background sound and test when your voice feels normal.
- The voice type looks wrong: lowest and highest notes cannot define it; use it as a starting point, and see the voice types guide.
Microphone use and privacy
Your browser controls microphone permission, and you can withdraw it in browser or device settings. The code of the ten specialised tools was searched for network, storage and recording calls and none that upload audio were found; that review has not been done for the homepage test yet. Cookies, analytics and other site technology are covered in the Privacy Policy, which is the source for data handling.
Use your result well
Treat a result as context, not a score. Record your measured range, compare later sessions under similar conditions, and use the vocal range chart for general reference. Do not force very high or low notes to widen it; persistent hoarseness, pain or unexplained voice changes need a qualified professional, and our vocal health tips cover general safety.
