Singing 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 the low and high notes you can sing comfortably, then see how far apart they are. The Singing Range Test supports guided microphone capture and manual entry of known notes. Its most useful result is a repeatable endpoint pair you can use when choosing practice material, rather than the widest span you can produce once.
If you searched for a singing test, begin by deciding what you want to learn. This page establishes boundaries and explains their span. Matching a target note, inspecting speaking frequency and completing a scored practice exercise are separate tasks. Knowing the difference helps you choose a useful next step instead of expecting one number to describe your whole voice.
Take a comfortable baseline measurement
Choose a time when your voice feels normal and rested. Move away from competing music, television and other speakers. A steady vowel or light hum is a better starting signal than a shouted word, a quick slide or a very breathy sound.
- Check an easy middle note. Start the microphone, allow access and sing one comfortable pitch. Make sure the display follows your voice before exploring the edges.
- Find a usable low note. Move downward gradually, pausing between attempts. Accept a pitch you can hold and repeat without pressing the voice.
- Wait for stability. The capture guide needs roughly 0.7 seconds of a sufficiently steady note. Crossing a pitch during a slide is not the same as sustaining it.
- Save the lower endpoint. Follow the low-note capture step, then move to the upper-note step.
- Explore upward conservatively. Return to an easy region before moving higher. Save a note that remains comfortable, rather than a single crack or squeak.
- Confirm the pair. After a short break, try both endpoints again. Keep the more repeatable boundary if the attempts disagree.
There is no need to raise loudness to make a high note count. Stop when the voice feels strained, painful or increasingly tired. Repeating an uncomfortable endpoint to change a browser result is not a useful practice goal. Ongoing voice symptoms need appropriate professional attention.
Use manual input when the notes are already known
You can select the low and high notes directly if a keyboard, teacher or previous careful test has identified them. Choose the full label, including the octave, then submit the pair. A manual result calculates the selected interval; it does not verify that you sang either note.
Middle C is C4 in this interface. C3 and C4 share a letter but are twelve semitones apart. B3 to C4, however, is just one semitone because the octave number changes at C. Checking the number is especially important when a result seems surprisingly wide.
Sharps and flats can name the same equal-tempered pitch, such as C-sharp and D-flat. That spelling choice is different from an octave error. If the piano reference sounds an octave away from your voice, resolve that mismatch before saving the endpoint.
Understand your semitone and octave span
A semitone is one step between neighboring chromatic piano notes. Twelve semitones make an octave. The test subtracts the lower note’s pitch number from the upper note’s number, then divides by twelve to express the distance in octaves.
| Endpoint pair | Distance | Octaves |
|---|---|---|
| E3 to B4 | 19 semitones | About 1.58 |
| A2 to A4 | 24 semitones | 2.00 |
| G3 to D5 | 19 semitones | About 1.58 |
E3-B4 and G3-D5 have the same distance but occupy different pitch regions. Their practical uses are therefore different even though the octave number agrees. Record the endpoints as well as the span; “1.58 octaves” alone leaves out where your voice sits.
Counting included keys gives another number. A2-A4 contains twenty-five chromatic pitch positions if both ends are counted, but the distance between them is twenty-four semitones. The result describes steps between pitches, not how many key labels appear in the interval.
Read reference labels as comparisons
The tool compares your span with seven illustrative vocal references: bass, baritone, tenor, countertenor, contralto, mezzo-soprano and soprano. They overlap because real singing categories cannot be reduced to non-overlapping strips on a piano.
The percentage compares the shared semitone interval with the total interval occupied by your pair and a reference. It is a geometric span match. It does not mean that a category is a certain percentage likely, or that your technique received a percentage grade.
A singer’s tessitura, or sustainable working region, can be more important to a part than the outermost notes. Two people with identical endpoints can find different phrases comfortable. Register transitions, tone and vocal weight also contribute context that this endpoint test does not measure.
Use the Voice Type Test to explore what those comparisons mean. The homepage does not match you to a famous singer or recommend songs from a database, and an overlapping reference does not assign a professional classification.
Make register choices explicit
Some singers can extend a result with a comfortable head-voice or falsetto pitch that they would not use in the same way as their modal notes. You can explore that extension, but note which registers the pair includes. Comparing a modal-only test with a later combined-register test mixes two definitions of range.
For practical singing, ask whether you can enter and leave the note, sustain it at an appropriate dynamic and use it in a phrase. A label that appears once does not establish those abilities. You may want a conservative working pair for repertoire and a separately noted exploratory extension.
The High Note Test gives more detail on checking an upper boundary. Its current interface uses the same low-then-high range workflow, so the low endpoint remains part of that result even when your main interest is the top note.
Resolve a surprising microphone result
The detector seeks a repeating fundamental frequency from one sound. A voice also has harmonics. When an overtone dominates, the estimate can jump an octave; a rough low signal can also lead to an implausible label. Background music or reference playback may be the sound detected instead of your voice.
First repeat an easy middle note. Stop any reference tone before singing, and consider headphones to keep playback separate from the microphone. Check the selected input device and keep a consistent distance. An overloaded or very faint signal is not improved simply by trying a more extreme pitch.
The microphone search covers approximately 50-2,000 Hz. That is different from the full range of note labels that can be selected or generated as references. A device, an unclear signal and the analysis limits can all affect extreme readings; the selector is not a guarantee of detection at every pitch.
If you need to see an individual note, use the Singing Note Detector. Its detected span includes whatever occurred in the sample, whereas this guided test asks you to confirm comfortable boundaries.
Choose the next tool from the question
For pitch matching, use the Pitch Accuracy Test and start with a comfortable target. A stable wrong note can be held beautifully while missing the intended melody. Range and target accuracy therefore provide different information.
For a scored exercise, the Singing Grader combines an entered span with five measured attempts using a disclosed custom formula. It does not judge a complete song. For ordinary speech in hertz, the Voice Frequency Test describes a timed speech sample rather than singing endpoints.
To rehearse a recording in a more suitable register, the Vocal Pitch Changer can shift a local file. The tool changes audio, not your physical voice. Check the transposed melody’s repeated high and low phrases instead of assuming an octave-span match guarantees comfort.
Keep a useful result record
Copy the summary or download CSV measurements. The range interface also provides a result image and a share link containing numeric values in the URL fragment. These are snapshots you can keep yourself, not a persistent account history or a saved audio recording.
Record the date, input method, tuning reference, register choices and whether the endpoints were repeatable. Small day-to-day differences can reflect conditions or sampling rather than lasting progress. Local microphone analysis does not upload a performance for a server to judge; that tool-specific statement does not describe unrelated website analytics or hosting activity.
Frequently asked questions
Can I take the range test without a microphone?
Yes. Enter a pair of notes identified with a reliable reference. The tool calculates their span and comparisons. Manual entry is not independent evidence that those pitches are comfortable for you.
Does a large range mean I am a good singer?
A wide pair describes boundaries. Control, rhythm, phrasing, expression and sustainable tessitura are different aspects of singing. A reliable smaller working range can be more useful than strained extremes.
Why did my result change on another day?
Your voice, register choices, microphone and room can differ. Repeat with a consistent procedure and compare the actual notes. One changed endpoint does not prove a lasting gain or loss.
Can speaking normally reveal my whole singing range?
No. Speech uses a different task and pitch distribution. A speaking median or low syllable cannot replace separate comfortable singing endpoints. Use the frequency tool for that speech question.
Should I include a high note that appeared for an instant?
Check it carefully. A slide, harmonic or crack can create a brief label. A repeatable stable note is more useful than the highest instantaneous reading, especially if the sound felt strained.
Will the test diagnose a vocal problem?
No. It measures pitch behavior for an informal singing task. It cannot diagnose a condition or explain continuing pain or hoarseness. Stop uncomfortable testing and seek appropriate help for persistent concerns.
