Vocal Range Finder — Map Your Singing Range & Voice Type
This free vocal range finder lets you sing your lowest note and highest note into your microphone as a quick singing range test. The tool maps your range in musical notes and Hz, estimates your voice type using a built-in voice classifier, and shows a few famous-singer examples so you can find your range in context.
ℹ Hold each note steadily for a moment so it registers (brief glitches are ignored). Your range depends on warm-up, technique, health, and time of day, so this is a snapshot, not a verdict. Voice-type classification is approximate — real classification also considers tessitura and timbre, not just range. Your mic is analyzed live and never recorded or uploaded.
How It Works
The tool detects the pitch of your voice in real time with the YIN algorithm — a widely used time-domain pitch estimator — and converts it to a musical note. As you sing, it remembers the lowest and highest notes you hold steadily — a short stability check means a sustained note counts but a passing squeak or click doesn’t. Your range is the distance between those two notes, shown in note names, Hz, and octaves (for reference, one octave = 12 semitones). The voice type is a best-fit guess: it compares the centre of your range to the typical Fach ranges of bass, baritone, tenor, alto, mezzo-soprano, and soprano voices. For a more granular real-time pitch readout with cents deviation, the Pitch Detector works alongside this tool. Everything runs live on your device; nothing is recorded.
Treat the result as a fun snapshot. Your usable range shifts with warm-up, technique, vocal health, and the time of day, and trained singers extend it with falsetto, head voice, and whistle register (also called flageolet). Real voice classification by a teacher weighs tessitura (where your voice sits comfortably) and timbre — qualities like brightness, depth, and resonance placement — not just the extremes, so two people with the same measured range can be different voice types. The famous-singer examples are rough associations, not exact matches.

What Is Passaggio, and How Does It Affect Voice Type?
The passaggio (Italian for "passage") is the transition zone between vocal registers. Most singers have two: a primo passaggio (chest-to-middle) and a secondo passaggio (middle-to-head voice). These points typically feel like a slight gear-change or instability in the voice. Critically, where your passaggi fall is one of the factors voice teachers use to assign a Fach classification — a baritone and a tenor can share identical measured ranges yet have passaggi a third apart, placing them in entirely different voice categories.
This is why voice type is not decided by range alone. Tessitura — the part of your range where the voice sits effortlessly, with the best tone and least fatigue — matters as much as the top and bottom extremes. Two singers who both reach C3 to C5 may have completely different tesitura and timbre, and a trained ear would classify them differently. A browser pitch tool like this one, or the Pitch Detector, can help you notice where your voice feels strained versus easy — a rough clue to tessitura. To locate the specific notes where your register shifts, sing a scale slowly through your break while watching the Chromatic Tuner for cent-level precision. But for a definitive Fach assessment, a voice teacher remains the right call: they hear the timbre and resonance placement that no pitch algorithm captures.
