What This Site Is
VocalRangeFinder.com is a free, browser-based tool that measures your singing range by detecting the pitch of notes you sustain into your microphone, tracking your lowest and highest confirmed notes across a session, and mapping the resulting range against established voice type classification criteria — with a full explanation of what the measurement means and what it cannot tell you on its own.
The site is built and maintained by Nance, vocal range researcher and voice health educator. Every tool, every explanation, and every piece of educational content on this site is Nance’s direct work. There are no advertisers, no sponsored recommendations, and no third-party contributors shaping what appears here.
Why This Site Exists
Most singers have sung their lowest and highest notes thousands of times. Very few have measured them. Knowing that you “have a big voice” or “can hit high notes” is different from knowing that your confirmed range spans B2 to B4 — 24 semitones, 2 octaves — which sits squarely in baritone territory by standard classification. The difference matters for repertoire selection, choral voice part assignment, understanding your instrument, and having informed conversations with a voice teacher.
The problem is access. Professional vocal range assessment requires a trained voice teacher and an in-person session. Consumer pitch apps typically measure a single note at a time rather than tracking a full range session. Browser tools exist but almost none of them document their measurement methodology — which notes were confirmed, over what duration threshold, against what classification references.
VocalRangeFinder.com was built to close that gap: a browser-based range tool that measures by confirming sustained notes from lowest to highest, displays the result in musical notation and Hz, classifies the range against documented voice type boundaries, and is transparent about every methodological choice and limitation. The complete measurement methodology is documented on the Methodology page.
What This Site Provides
The Vocal Range Finder A browser-based vocal range measurement tool. You sing notes from your lowest to your highest into your microphone. The tool detects the fundamental frequency of each note using YIN/FFT pitch analysis, confirms each note when held for the required duration, tracks your lowest and highest confirmed pitches across the session, and maps the resulting range against soprano, mezzo-soprano, alto, tenor, baritone, and bass classification boundaries. All processing is local — nothing is transmitted. See the Data Security page for the full explanation.
Educational Content Articles and explainers covering singing range science, vocal register classification, the relationship between Hz frequency and voice type, voice health and range preservation, how range changes with training and age, and how to measure your range accurately and safely. All content is written to be scientifically grounded and genuinely useful.
Accuracy and Limitations Documentation Every result and accuracy claim on this site includes an honest account of what the measurement captures and what it does not. Range measurement accuracy, note confirmation logic, and the reasons why range alone cannot produce a definitive Fach classification are all documented explicitly. The FAQ covers the most common questions about range measurement results.
Who This Site Is For
Singers wanting a documented range measurement Whether you are a beginner exploring your voice, an intermediate singer preparing for auditions, or an experienced performer wanting a precise reference point, VocalRangeFinder.com gives you a measured range with the scientific context to understand it.
Choral singers and voice part assignment Choral directors and singers use range as the primary criterion for voice part assignment. A documented, measured range is a more reliable reference than a self-reported one.
Voice students preparing for teacher consultations Arriving at a lesson with a measured range — rather than a vague sense of your voice — gives a teacher useful data to work with from the first session.
Adults curious about their voice type Voice type is not just a professional musician’s concern. Understanding where your voice sits in the standard classification system, and why, is interesting and useful regardless of your musical background.
Voice health educators and researchers VocalRangeFinder.com provides documented technical reference material on browser-based vocal range measurement, including methodology, accuracy figures, and known measurement limitations.
Accuracy and Transparency
Nance does not publish range boundaries, voice type references, or measurement accuracy figures without traceable sources. All content is cross-referenced against published vocal science literature and the W3C Web Audio API specification. Limitations are documented on every relevant page.
