Sam Cooke
Vocal Range Researcher & Singing Tools Developer | Founder, SingingRangeTest.com
My name is Sam Cooke. I have spent the last five years researching vocal range science, singing technique, and the way the human voice organises itself across different registers — and building tools that help singers and curious listeners understand their own voice in practical, measurable terms.
SingingRangeTest.com exists because I grew frustrated with a specific problem: most singing range tests treat your voice as a single number. They tell you your range spans from C3 to A5 and leave you with nothing useful. No register breakdown. No explanation of where your chest voice ends and your head voice begins. No context for what the result actually means for singing.
The test on this site was built to fix that — to give singers a result they can actually use.
What I Research and Write About
My work on SingingRangeTest.com covers four areas:
Vocal register science. The human voice does not operate as a single continuous instrument — it moves through distinct registers, each with different physiological and acoustic characteristics. I research how chest voice, mixed voice, head voice, and falsetto interact, where the passaggio (transition zones) typically fall, and how register control affects a singer’s practical range. Every test on this site is built around this register-level understanding, not just a lowest-to-highest measurement.
Voice type classification. I research and document the standard voice type categories — soprano, mezzo-soprano, contralto, tenor, baritone, bass — and the acoustic and range criteria that define each one. The site’s singer vocal range articles all approach classification from this research framework: not just listing notes, but contextualising what those notes mean within established vocal typology.
Singer vocal range analysis. SingingRangeTest.com publishes documented vocal range analyses for well-known artists, researched from studio recordings, live performances, and verified sources. I distinguish between a singer’s comfortable working range and their documented extreme range — a distinction that matters enormously for accurate classification. Where sources conflict or range data is disputed, the article says so rather than presenting a single figure as fact.
Tool methodology and accuracy. Every tool on this site — from the full three-mode Singing Range Test to the Pitch Accuracy Test, High Note Test, Low Note Test, and Singing Note Detector — uses browser-based pitch detection via the Web Audio API. I document how each tool measures what it claims to measure, what the environmental and technical variables that affect accuracy are, and what the tools cannot do. Transparency about limitations is as important to me as explaining the capabilities.
Why I Built These Tools
The gap I was trying to close was not just measurement — it was meaning.
A singer who tests their range and gets back “E2 to B4” learns very little. A singer who finds out that their chest voice runs comfortably from E2 to D4, that their passaggio sits around E4 to F4, that their head voice extends from G4 to B4, and that this profile is consistent with a high baritone voice type — that singer leaves knowing something genuinely useful about their instrument.
That is the difference this site is built to provide. Not just a number, but a map.
My Research and Accuracy Standards
Every article and tool page on this site is held to the same standard before publication:
- Singer range data is cross-referenced from multiple recorded sources — not estimated or copied from other sites
- Voice type classifications are grounded in established vocal pedagogy and acoustic science
- Tool limitations are disclosed clearly on every relevant page — I do not claim browser-based pitch detection is a substitute for professional vocal assessment
- Educational articles are written to be genuinely useful to the reader, not padded to meet a word count
- Where research is uncertain or expert opinion varies, the content says so rather than overstating confidence
If you find an error anywhere on this site — a singer’s range listed incorrectly, a technical claim that does not hold up, a tool behaving unexpectedly — please report it via the Contact page. All corrections are reviewed personally and applied promptly.
Tools on This Site
The tools on SingingRangeTest.com are built around the real questions singers ask about their voice:
- Singing Range Test — full multi-register vocal assessment with Quick, Professional, and Guided test modes
- Vocal Range Calculator — measure your lowest and highest singable notes
- Pitch Accuracy Test — measure how consistently you hit and hold target pitches
- High Note Test — test the upper limit of your singing range
- Low Note Test — test the lower limit of your singing range
- Singing Note Detector — identify the note name of any pitch you sing
- Voice Type Test — estimate your voice classification based on your range
- Singer Comparison Tool — compare your range to documented singer ranges
- Perfect Pitch Test — test your ability to identify notes without a reference
All tools run in your browser. No audio is recorded, stored, or transmitted. When you close the page, your voice data is cleared.
