In short: Every page on VocalRangeTest.com should help you understand or use your voice, say how sure we are, and be corrected when it is wrong. Pages are written or reviewed by Erika Parker, tools are tested before release, and ads and affiliate links never decide what we say.
Who Writes and Reviews Content
Pages are written or reviewed by Erika Parker, who runs the site. Nothing is published automatically: each page and each tool release is checked before it goes live. More about the site is on the about page.
We use AI assistants for parts of the work, such as organizing research, drafting and writing tool code. AI output is never published as it comes: facts, numbers and note names are checked, and tools go through the tests described on the methodology page. We don’t use automation to publish large numbers of near-identical pages.
What We Publish
- Tools that measure range, pitch and voice type, listed on the tools page.
- Guides that explain the results, such as how to find your vocal range and the voice types guide.
- Singer profiles: the documented range of well-known singers, collected in famous singers’ vocal ranges.
- Singing resources, including a few pages about online lessons (see Commercial Relationships below).
Sources We Rely On
We prefer the source closest to the fact:
- For singers: the recordings and filmed performances themselves, and interviews in which the singer talks about their voice.
- For voice science: published research and reference books. For example, the speaking-pitch bands in our Voice Frequency Test (about 90–155 Hz for adult men and 165–255 Hz for adult women) come from R. J. Baken’s Clinical Measurement of Speech and Voice.
- For tool methods: published algorithms, such as the YIN pitch detector (de Cheveigné and Kawahara, 2002) that our tools use.
- For music theory: the equal-tempered scale with A4 = 440 Hz, which fixes every note’s frequency.
A popular claim repeated on many websites is not evidence. When good sources disagree, we say so instead of picking the most exciting number.
Singer Vocal Range Standards
Singer ranges are easy to exaggerate, so these pages follow extra rules:
- A note counts only if it is clearly audible and clearly the singer’s, not a backing vocal or studio effect.
- We say how a note was produced when it matters: chest voice, falsetto, whistle register or vocal fry. Whether those notes count is a choice, explained in does falsetto count in vocal range.
- Total range is kept apart from tessitura, the area a singer uses most. One extreme note does not define a voice type.
- The Singer Comparison Tool uses one checked range per singer, taken from that singer’s page, so the tool and the page agree.
While building that tool in September 2026 we found singer pages whose title, body and FAQ gave different ranges. Those pages are flagged for correction, and the tool excludes singers whose page has no clear full range.
Tool Standards
A tool is released only after a written test report: known reference notes and synthetic voices through a simulated microphone, manual input checks, mobile layouts, error messages and microphone clean-up. The report also lists what could not be tested. The results are on the methodology page. The text around a tool must describe what the tool really does, in the same terms.
Health and Safety Content
Articles about warm-ups, strain and vocal health are general education. They don’t diagnose anything, and they don’t push readers to force high or low notes. When symptoms such as pain, hoarseness lasting weeks or sudden voice loss come up, we point readers to a doctor, an ENT specialist or a speech-language pathologist. See the disclaimer.
Commercial Relationships
The site is funded by display ads served by Journey by Mediavine and by one affiliate partner, the online course 30 Day Singer. Four pages link to its free trial through affiliate links: the 30 Day Singer review, best online singing lessons, beginner singing lessons and free singing course. If you start a paid membership through one of those links, we may earn a commission at no extra cost to you.
- Each of those pages carries a disclosure at the top, and the links are marked as sponsored.
- The commission doesn’t change what we recommend, and those pages also cover free options and other ways to learn.
- We don’t publish star ratings, invented testimonials or claims of personal results we can’t back up.
- Advertisers have no influence on our content or tool results, and an ad on the site is not an endorsement.
Corrections and Updates
If a page is wrong, we fix the page itself: the wrong statement is corrected, context is added, or a singer’s range is revised with the evidence. When a tool’s result was affected, the tool is fixed and retested, and the check that would have caught the problem is added to its tests. The “last updated” date changes only for real changes, not to make a page look new. Spelling fixes don’t get a notice.
To report an error, email info@vocalrangetest.com or use the contact page, with the page address and the statement or result in question. A source or the time stamp of a recording helps most.
Privacy and Accessibility
What we say about privacy must match what the tools do. They analyze audio in your browser and don’t record or upload it; the details are in our privacy policy. We also try to keep every tool usable without a microphone and with a keyboard; see our accessibility statement.
