Short answers about the singing range test and the other tools on SingingRangeTest.com. For the exact rules of each tool, see Testing Methodology; for what can affect a result, Accuracy & Limitations; for a step-by-step walk-through, How the Singing Range Test Works.
Using the tools
What does the singing range test measure?
The lowest and highest stable pitches accepted during your session, and the span between them in semitones and octaves. Depending on the mode it may add educational estimates such as a broad voice type. It shows what was detected in that session, not your permanent maximum or your full usable range.
Which tool should I use?
Use the homepage range test for your lowest and highest notes. For narrower questions: the Pitch Accuracy Test for how in tune you are, the Singing Grader for a 1 to 10 grade, the Voice Frequency Test for your pitch in Hz, the Note Finder for the notes in a phrase or audio file, the Voice Quality Test for one held vowel, and the Vocal Pitch Changer to shift a recording. The tools page lists them all.
Which homepage test mode should I use?
The homepage currently offers Quick, Professional and Guided modes. Quick is the simplest range check, Professional is more structured, and Guided gives step-by-step instructions. The live interface is the source for what each mode does, because features can change.
Do I need an account or a download?
No. The tools run in your browser; you open a page, allow the microphone when asked, and follow the on-screen steps.
Does it work on phones?
The tools are built for current desktop and mobile browsers, but the rebuilt tools have so far been tested only with simulated browsers and a fake microphone (Chrome and Edge engines), not on real phones, Safari or Firefox. If a tool will not start or misbehaves, try a current version of Chrome or Edge, and tell us the device and browser through Contact Us.
What if my microphone does not work?
Check that your browser has permission to use it, that the right input device is selected, that no other app is using it, and your device privacy settings; then reload. If you opened the page inside another app (social media, for example), open it in your normal browser instead. If it still fails, contact us with your device, browser and the tool URL.
Is my voice recorded or stored?
For the ten specialised tools, we searched the code for network, storage and recording calls and found none that send audio anywhere; the audio is analysed in your browser. Two details: Note Finder saves four settings in your browser, and the Vocal Pitch Changer records your take into your device’s memory when you press Record. The homepage range test has not had this code review yet, so we cannot make the same statement for it. The Privacy Policy covers cookies, analytics and other data practices.
Understanding your results
What is vocal range?
The span between the lowest and highest pitches a person can produce. A measured range can include notes you reach only briefly, so it is not the same as your comfortable singing range.
What is a good vocal range?
There is no octave count that makes a good singer. Control, pitch accuracy, consistency, tone and expression matter too, and a smaller comfortable range used well can beat a wider one made of forced notes. See the vocal range chart for typical ranges.
Why does my range change between tests?
Microphone and device, background noise, pitch stability, how you sing, temporary vocal condition, microphone position and browser behaviour all play a part. Compare sessions under similar conditions.
What if one note looks obviously wrong?
Repeat it. Pitch detectors can make octave errors or react to background sound and harmonics. A surprising extreme that you cannot reproduce should not be trusted.
Does a wider range make me a better singer?
No. Two singers with the same range can differ greatly in pitch accuracy, control, tone, tessitura, stamina and expression.
Can I improve my range?
Usable range can change with training, coordination and experience, and progress varies. Aim to develop notes with control rather than forcing extremes; these exercises that can help extend your range are a starting point.
How often should I retest?
There is no schedule. Retest when it is useful, ideally under similar conditions, and avoid testing extreme notes repeatedly in one sitting.
Scores, grades and estimates
How is the Singing Grader score calculated?
It finds the notes you hold for at least 0.4 seconds (at least three are needed), then combines four sub-scores: 60% centring on the semitone grid, 20% steadiness, 10% clear-pitch time and 10% range used, each from 0 to 10. The result shows the sum with your own numbers. It does not score rhythm, timing, tone or whether you sang the right notes of a song, and its cut-offs are our own decisions, not calibrated on real voices.
What does the Pitch Accuracy Test score mean?
Each note earns 100 points if you are within 5 cents of the target, falling in a straight line to 0 at 50 cents or more; missed notes score 0, and the score is the average. The ±30, ±20 or ±10 cent setting only decides whether a note counts as “in tune”. The wording of the verdict (excellent, good, fair) is the tool’s own.
How is the voice type worked out?
The three-note voice type estimate compares your lowest, highest and optional easiest note with six fixed textbook ranges and shows the closest match. It is an estimate: voice classification also involves tessitura, timbre, vocal weight, register transitions, technique and repertoire. See the voice types guide.
Can a tool tell my register, passaggio or tessitura?
No. Pitch alone cannot show which register produced a note, and no tool detects a passaggio. The voice type estimate shows a comfortable zone by a fixed rule (your lowest note plus two semitones up to your highest minus five), which is an approximation, not a measurement of comfort.
Why does the Voice Frequency Test say my voice is low, middle or high?
It compares your median pitch with the tool’s own bands (for example under 100 Hz “very low”, 150–199 Hz “middle”, 260 Hz and above “very high”). Adult voices overlap widely, pitch is not the only thing that makes a voice sound deep, and the tool draws no conclusion about gender, age or health.
Can it detect chords or a song with music?
No. All the note-detecting tools follow one note at a time. Chords and backing music give no reading or a wrong one; on generated chords, C4 plus E4 was read as C2.
Accuracy and vocal safety
How accurate is it?
We do not publish an accuracy percentage. The rebuilt tools were tested with generated signals, and detectors were within about 2 cents on clean generated tones, but they have not been tested with real voices or microphones, and the homepage test has not had that review. Real accuracy depends on your microphone, room and how you sing. See Accuracy & Limitations.
Can the test tell if I am straining or if my voice is healthy?
No. It can tell that a pitch was stable, not whether it was comfortable, strained or healthy. No tool here inspects the vocal folds or diagnoses anything. Stop if a note hurts, and see our vocal health tips.
Should I test while hoarse or ill?
Avoid forcing extreme notes when your voice is hoarse, painful or tired; a result then may not represent your normal voice. Persistent pain, recurring voice loss or unexplained hoarseness should be discussed with a qualified healthcare professional.
Should I warm up first?
Many singers start gently with comfortable sounds before exploring extremes. There is no universal warm-up length that guarantees a perfect result.
Is this a medical assessment?
No. SingingRangeTest.com does not diagnose voice disorders, injuries or medical conditions.
About SingingRangeTest.com
Who runs the site?
SingingRangeTest.com is created and maintained by Sam Cooke, who researches vocal-range topics, maintains the tools and content, and reviews corrections. See the Author page and About Us.
How are singer vocal ranges researched?
Singer-range claims are checked against identifiable recordings, documented live performances, primary material and reputable published sources where possible. We separate representative range from isolated extreme notes when the evidence allows, and qualify disputed information. The full process is in the Editorial Guidelines.
Does the site use AI to create content?
AI tools may assist with drafting, editing, organisation or research workflow. AI output is not treated as factual evidence, and published content is reviewed and edited under the Editorial Guidelines.
How are errors corrected, and how do I report a problem?
If you report a factual, technical or singer-range error, we review the evidence and correct confirmed errors where appropriate. Use Contact Us and include the tool or page URL, your device and browser, what happened, what you expected, and a screenshot if helpful. You can suggest tools, topics or singers the same way.
