About SingingRangeTest

SingingRangeTest.com is an independent educational website for singers who want to understand their vocal range, voice type, pitch and registers. It pairs free browser-based voice tools with guides that explain what a result means, what can affect it and where it stops being useful.

The site was created and is maintained by Sam Cooke. The Author page explains what that work involves.

Why the site exists

A vocal range result on its own does not tell the whole story. Two singers can reach the same notes and still differ in comfortable range, tone, register transitions and control, and one unusually high or low note does not decide a voice type. The site exists to put results in context. It aims to help you:

  • measure and explore your vocal range;
  • tell the difference between the notes you can reach and the notes you can sing comfortably;
  • see how voice types are generally classified;
  • understand what can change a test result;
  • use singing tools with realistic expectations.

The site is for education and personal exploration. It is not a professional or clinical voice assessment.

The tools on this site

Tools that listen ask for microphone permission when you start them. The main range test is on the homepage; the ten tools below each do one job. Browse them all in the tools directory.

  • Singing Range Test (homepage): sing your lowest and highest notes to find your range.
  • Pitch Accuracy Test: hear a note, sing it back and see how many cents sharp or flat you were, with a score out of 100. It also has a listening test where you judge whether a second note is higher or lower.
  • Singing Grader: sing anything, hum or sing a scale for 15, 20 or 30 seconds and get a grade out of 10 with sub-scores for how close your held notes were to a note, how steady they were and how much of the take had a clear pitch.
  • a climbing game for your top note: sing target notes that step upward and see the highest note you held. It does not measure your lowest note or your whole range.
  • Voice Frequency Test: measure the fundamental frequency of your speaking or singing voice in Hz over 10, 20 or 30 seconds.
  • a live note readout: see the note, frequency and cents sharp or flat as you sing one note at a time. It cannot read chords or a song with backing music.
  • a voice type estimate: enter or sing your lowest, highest and easiest notes and compare them with a chart of typical ranges. The result is an estimate, not a classification.
  • Note Finder: see the notes you sing on a staff and a keyboard, or open a recording to list the notes in it.
  • Voice Quality Test: measure acoustic properties of a held vowel, such as jitter, shimmer and harmonics-to-noise ratio. It is for curiosity and does not assess health.
  • a scale matcher for your melody: sing a melody and see which scales it fits, with the notes of each scale and a playback.
  • Vocal Pitch Changer: change the pitch of a recording you make or open, compare before and after, and export MP3 or WAV (up to 100 MB and 6 minutes).

A tool can measure a frequency directly. A voice type, a grade or a scale match is an interpretation of that measurement, and each tool page says which is which.

How the tools were checked

Before release, the tool code was reviewed and run through automated tests using synthetic test tones, a simulated microphone and automated browsers. That is not the same as real-world testing. The ten tools above have not yet been tested with real voices on real microphones, in Safari or Firefox, or on phones and tablets, so this site does not publish accuracy percentages for them. Results can differ from one microphone, room and browser to the next.

You can read the technical principles in the Testing Methodology, a plainer walk-through in How It Works, and the factors that affect results on Accuracy & Limitations.

Guides and singer research

The guides cover topics such as voice types, how tessitura differs from range, typical ranges by voice and how to find your vocal range. They try to separate commonly repeated rules from what is more nuanced in real singing. Reaching one note does not make someone a tenor, soprano, alto or bass; classification also depends on comfortable range, tone, register behaviour, training and musical context.

The site also publishes vocal-range profiles of well-known singers. Published ranges vary by source because they may count studio or live recordings, backing vocals, falsetto, effects or single extreme notes. Where the evidence allows, the profiles separate reported extremes from a singer’s more representative range and name their sources.

Sources and editorial standards

For claims about vocal science, anatomy, acoustics or health, the site aims to use credible sources, and to cross-check singer ranges rather than repeat a single unsourced figure. Some drafting and research uses AI-assisted tools; content is reviewed and edited before publication. The full process, including corrections and updates, is in the Editorial Guidelines.

Accuracy, limits and vocal safety

A test records what you produce in one session. It should not be treated as your permanent maximum range or a professional voice classification. Microphone quality, background noise, room acoustics, warm-up, fatigue and how strongly you sing a note all affect results.

Singing should not need persistent pain or strain, so do not force extreme notes to improve a result (see Vocal Health Tips). The site does not diagnose vocal injuries, disorders or medical conditions. If you have persistent pain, hoarseness or voice loss, speak to a qualified healthcare professional.

Privacy and microphone use

For the ten tools listed above, the code was reviewed for network requests, storage and recording. Audio is read from the microphone into the browser’s audio analyser and analysed in memory, and the tool code makes no network requests, so no audio is uploaded. Two details: Vocal Pitch Changer keeps a recording or opened file in your browser’s memory so it can change the pitch, and Note Finder saves a few settings, such as the reference pitch, in your browser’s local storage. This was checked by reading the code and running automated checks, not by watching network traffic in a real browser, and the statement does not yet cover the homepage range test.

Cookies, analytics and other data practices are separate from the tools. The Privacy Policy is the controlling source for current details.

Independence

SingingRangeTest.com is an independent website. It is not a music school, record label, artist-management company or medical provider, and it is not a substitute for a qualified vocal professional. Advertising, affiliate links or other commercial relationships, where they appear, are not allowed to determine factual conclusions or change editorial standards.

Corrections and contact

If you find a wrong note or frequency, an unsupported singer-range claim, outdated information, a broken tool, an accessibility problem or a privacy concern, tell us through the Contact page. Credible corrections and stronger evidence lead to a review and, where appropriate, an update.
