Vocal Range Test
- 1 Comfortable low
- 2 Comfortable high
- 3 Your range
Use one clear sound in a quiet room. Your audio stays in this browser.
Warm up gently. Save only notes you can repeat comfortably; stop if singing feels strained.
Reference ranges overlap. These comparisons describe note-range similarity, not a definitive voice classification, probability or assessment of tessitura and tone.
Settings & measurement notes
Microphone input is analyzed in memory; audio is never recorded or uploaded by this plugin. Stopping, hiding or leaving the page releases the microphone. Reference tones temporarily pause analysis.
Pitch estimates can be affected by breathy or irregular sounds, harmonics and microphone processing. This is a single-note tool, not a medical or professional voice assessment.
A4 defaults to 440 Hz. One octave doubles frequency; one semitone is 1/12 of an octave. The detector uses the McLeod pitch method with clarity and stable-note filtering.

Find your lowest and highest comfortable singing notes, then see the span between them in semitones and octaves. Start the Vocal Range Test with your microphone or enter endpoints you already know. The result gives you a practical range record and approximate reference comparisons, not a final judgment of voice type or singing ability.
The useful question is not how far you can push your voice once. It is which notes you can repeat clearly and comfortably. Use those endpoints as a starting point for song selection, practice and discussion with a singing teacher, while keeping tessitura and register in mind.
Take the vocal range test
- Begin gently. Warm up in an easy register and use a quiet place without a backing track.
- Choose microphone input. Start the microphone and allow access. Select the intended device in Settings if necessary.
- Find a comfortable low. Move downward gradually, then hold a clear note while the stable-note indicator fills.
- Save the low endpoint. Check its note name and octave before continuing.
- Find and save a comfortable high. Work upward without forcing; repeat an uncertain result instead of accepting a brief spike.
- Review the range. Read the two notes, interval distance, frequencies and reference-span comparisons.
The hold indicator asks for about 0.7 seconds of stable input. That helps distinguish a sustained detection from a momentary extreme, but it cannot feel whether you are straining. Your comfort and ability to repeat the sound remain part of the decision.
If a step is uncertain, redo it. A carefully checked smaller range is a better baseline than an impressive-looking result caused by a tracking error or an uncomfortable sound.
Enter known notes without microphone access
Manual mode calculates from selected low and high notes. Use it when you have checked your endpoints on an instrument or with another reliable note reference. Reference playback can help locate a selected pitch, but choosing a note is not evidence that you sang it.
Keep the octave number. G3 and G4 share a letter but are an octave apart. A correct letter with an incorrect octave changes the result substantially. The Vocal Range Calculator provides a focused explanation of this known-endpoint workflow.
You do not need microphone permission for manual calculation. If you later share the result, preserve whether it came from measured endpoints or entries you supplied. That distinction helps another person understand what was actually checked.
Understand semitones, octaves and endpoint counting
The tool measures the distance between endpoints on a twelve-tone equal-tempered grid. Twelve semitones make one octave. Subtract the low note’s MIDI number from the high note’s number, then divide by twelve for octaves.
For an illustrative pair, G3 is MIDI 55 and E5 is MIDI 76. The difference is 21 semitones, or 1.75 octaves. There are 22 chromatic note positions when you count both endpoints, but the distance between them is still 21 semitones.
Frequency follows ratios rather than fixed hertz steps. At A4 = 440 Hz, G3 is about 195.998 Hz and E5 about 659.255 Hz. A change of one octave doubles frequency. The same hertz difference in another register would not necessarily describe the same musical interval.
The Octave Range Test concentrates on reading these interval results. A fractional octave is meaningful; your range does not need to end at matching letter names to be described in octaves.
Read reference voice ranges as comparisons
The result compares your endpoints with seven illustrative reference spans. They overlap and are not universal boundaries. A span match describes interval overlap with the selected reference, not the probability that you belong to a professional category.
| Reference | Illustrative endpoints |
|---|---|
| Bass | E2–E4 |
| Baritone | A2–A4 |
| Tenor | C3–C5 |
| Countertenor | E3–E5 |
| Contralto | F3–F5 |
| Mezzo-soprano | A3–A5 |
| Soprano | C4–C6 |
A singer can reach outside a reference span and still find its usual repertoire comfortable, or match its extremes while finding that repertoire tiring. The Voice Type Test explains those limits in more detail. Use the label as context rather than a restriction on what you may learn.
Range is different from tessitura and register
Total range is the distance between your chosen endpoints. Tessitura concerns the region in which a phrase or song spends its time and where a voice can work comfortably. A melody may lie inside your extremes yet remain demanding because it stays near one edge.
Register choices and transitions also matter. The detector measures pitch, not whether you used chest voice, head voice, falsetto or another production strategy. Record that context yourself when it matters to your practice. A briefly reached extreme in one register is not automatically a comfortable sustained note for every style.
Two people with identical endpoints can have different tone, stamina, transitions and musical needs. The range result does not assess resonance, expression, breath management or vocal health. It should support useful questions rather than replace a fuller listening assessment.
Use the result to check a song
Compare the melody’s actual lowest and highest notes with your repeatable range. Then inspect its sustained and repeated passages, not only the single highest note. The key printed on a chart does not by itself tell you how high the melody lies.
The Song Key Finder estimates tonal candidates from a recording, but key and vocal range are different properties. A song in C can be arranged in several octaves and can suit different voices in different versions.
The Singer Comparison Tool compares your interval with reported singer spans. It does not show that you sound like a particular singer or can comfortably perform all of that singer’s songs. Use an actual melody and arrangement for the final practical check.
Turn the endpoints into a useful practice note
Write down the two notes, how you produced them and whether each one felt repeatable. A record such as “comfortable low after a gentle warm-up; upper endpoint in a lighter register” preserves information that an interval alone cannot explain.
Keep an easy working area inside those endpoints for repeated phrases. If a passage becomes tiring despite fitting numerically, the range calculation has not failed: it simply does not measure how long you can sustain that passage or how you navigate its transitions.
When a later result differs, compare the conditions before treating it as a gain or loss. You may have used another vowel, register, room or microphone. Recheck the same endpoint on another comfortable attempt and retain the uncertainty if the two readings disagree.
A useful next step can be as small as confirming the octave of one doubtful note. You do not need a new label or a larger span every time you test. The goal is a reliable reference for the singing you actually want to do.
Keep endpoint tracking believable
A harmonic can make the detector show an octave above the intended fundamental. Irregular low sounds or a noisy attack can also produce misleading readings. Repeat an unexpected extreme and compare its note with a reference before saving it.
A single-note microphone method is not a full-song transcription system. Background accompaniment, another singer or reference audio from speakers can compete with your voice. Reduce those sources and use one clear comfortable sound.
Calibrate room noise while the microphone is active and you are quiet. This adjusts the noise gate, not laboratory pitch accuracy. Raising the gate too far can reject a quiet intended note. The Note Detector can help check an individual note separately.
Save and share the range deliberately
Copy and CSV preserve result information. On this homepage, Download result card creates a PNG reference, while Copy result link carries the selected endpoints and A4 reference in the URL fragment. The link does not contain an audio recording; anyone you share it with can see the represented values.
A shared manual result is not proof of a newly measured performance. Keep the test conditions and origin with your own record. If you want to compare progress, repeat the same task under similar microphone and room conditions instead of interpreting every small daily difference as a lasting change.
Microphone analysis happens in browser memory without this plugin recording or uploading the voice. Stop, hide or leave the page to release input. These statements describe the tool’s processing, not the behavior of every unrelated service on the website.
Choose the next task after finding your endpoints
For deliberate target-note work inside your comfortable range, use the Pitch Test or Singing Test. They measure defined pitch attempts rather than assuming a wider range means better singing.
For a short speaking-frequency sample, use the Voice Frequency Test. Speaking pitch, target accuracy and total singing range answer different questions. Keeping them separate makes each result easier to use honestly.
Frequently asked questions
How do I find my vocal range online?
Capture a comfortable stable low and high note, verify their octaves and calculate the distance. Repeat doubtful endpoints rather than forcing extremes.
Can I test without a microphone?
Yes. Enter notes manually, while recognizing that the calculation cannot verify which notes you can sing.
Does a wide range mean a better singer?
No. Range does not measure rhythm, expression, technique, tone or the suitability of a performance.
Will the result tell me my exact voice type?
It gives approximate span comparisons. Tessitura, register behavior and other musical context are not determined by two endpoints.
Should I count a note that hurts or feels forced?
No. Stop an uncomfortable attempt and use repeatable comfortable notes for this baseline.
Does the result link share my voice recording?
No recording is created by this workflow. The link represents endpoint and tuning values, which the recipient can read.
