Voice Classification Reference

All Seven Vocal Range Types Explained

The Western classical voice classification system divides singers into seven main types based on their vocal range, timbre, and tessitura. Use this free online vocal range test to find which category fits you — no registration required.

👩

Soprano

C4 – C6 (261 – 1047 Hz)

The highest female voice type. Sopranos typically sing melody lines in choirs and are cast as the romantic lead in opera. The most common female voice type, subdivided into coloratura, lyric, and dramatic soprano. Test yours free — no registration needed.

Mariah CareyCeline DionWhitney HoustonMaria Callas

🎤

Mezzo-Soprano

A3 – A5 (220 – 880 Hz)

The middle female voice, darker and richer than soprano. Mezzo-sopranos often play mothers, villains, or witches in opera. The second most common female voice type with a warmer, fuller tone quality that sits naturally in the mid-range.

AdeleAmy WinehouseJessye Norman

🎵

Contralto (Alto)

F3 – F5 (175 – 698 Hz)

The lowest female voice type, with a rich, deep, and resonant quality. True contraltos are relatively rare. In choirs, the alto section includes both mezzo-sopranos and contraltos. Known for a distinctive dark, chest-dominant tone color.

CherTracy ChapmanNina Simone

👨

Tenor

C3 – C5 (130 – 523 Hz)

The highest common male voice type. Tenors sing the romantic lead in opera and typically carry the melody in male-voice choral writing. Known for brilliant, ringing high notes. Subdivided into lyric, dramatic, and heldentenor categories.

PavarottiEd SheeranBruno MarsFreddie Mercury

🎶

Baritone

G2 – G4 (98 – 392 Hz)

The middle male voice type — the most common male classification. Baritones blend the brightness of tenor with the depth of bass, making them extremely versatile. The most common male voice type found in popular music, folk, and choral singing.

Johnny CashElvis PresleyFrank SinatraDavid Bowie

🎸

Bass-Baritone

E2 – E4 (82 – 330 Hz)

A transitional voice type between bass and baritone, possessing both the power of bass in the lower register and the agility of baritone in the upper register. Often cast as authority figures, kings, or gods in operatic repertoire.

Barry WhiteNick CaveLeonard Cohen

🎼

Bass

E2 – E4 (82 – 330 Hz)

The lowest male voice type, characterized by a profound, deep, and resonant tone quality. True basses are relatively rare. Subdivided into bass-profundo (deepest possible) and basso cantante (singing bass). Essential in choral harmony foundations.

Vocal Test Tips

How to Get the Most Accurate Vocal Range Results

Getting accurate results from this free online vocal range test takes a little preparation. Follow these tips to ensure your pitch is detected correctly and your range is measured to its true extent — no registration required.

Warm Up First

Never test your range cold. Spend 5–10 minutes on gentle vocal warm-ups — lip trills, humming scales, and vowel sirens from comfortable mid-range. Cold voices are restricted by 3–5 semitones at both ends of the range, giving inaccurate results.

Use a Sustained Vowel

Hold a sustained "ahhh" or "eee" vowel on each note rather than speaking or singing words. Consistent vowels give the pitch detector a clean, stable fundamental frequency to analyse — consonants and transitions create false readings.

Start in the Middle

Begin testing from your comfortable middle register, then slide gradually downward to find your lowest supportable note, then start again from the middle and slide upward. This prevents vocal strain and gives the most accurate extremes.

Include Both Registers

Male singers: include both chest voice and falsetto. Female singers: include both chest and head voice. Your full range includes all phonation modes. Note separately if you want to measure chest-only range versus full range including head voice.

Stay 15–20cm from Mic

Position your mouth 15–20cm from your microphone — close enough for clear pickup but far enough to avoid plosive distortion on low notes and breath noise on high notes. Angling slightly off-axis reduces plosive interference.

Quiet Environment

Background noise confuses pitch detection algorithms. Use this free vocal range test in a quiet room with the door closed. Turn off fans, AC, and TV. Even moderate background noise can cause false note detections that skew your range measurement.

Don't Strain

Your range for this free test should be your comfortable singable range — notes you could sustain for a musical phrase, not strained extremes squeezed out once. The most useful range data for voice type classification is your tessitura, not your absolute limits.

Test Multiple Times

Vocal range varies with time of day (lower in morning), hydration, fatigue, and illness. For the most accurate results, test this free vocal range tool on multiple days at different times of day. Average the results for a more representative measurement of your true range.

Step-by-Step Guide

How the Free Vocal Range Test Works

This free online vocal range tool uses real-time pitch detection powered by the Web Audio API. No plugins, no downloads, no registration. Here's exactly what happens during your free vocal range test — start to finish in under 2 minutes.

Click Start Vocal Test

Clicking Start activates the Web Audio API in your browser. No software is installed, no audio is sent to any server. The tool connects to your microphone entirely within your browser session. 100% free, no registration needed.

Allow Microphone Access

Grant microphone permission in your browser's permission popup. The vocal range test needs access to your microphone to detect your pitch in real time. All audio processing is local — your voice is never transmitted or stored anywhere.

Warm Up & Start Singing

Warm up your voice for 5 minutes, then sing a sustained vowel into your microphone. The YIN pitch detection algorithm analyses your audio signal in real time and identifies the fundamental frequency of your voice within milliseconds.

Find Your Lowest Note

Slide your voice downward gradually, holding each note for 2–3 seconds. Watch the piano keyboard — the detected note lights up in real time. When you reach your lowest comfortable note, click "Mark as Lowest" to record it as your range floor.

Find Your Highest Note

Return to a comfortable middle note, then slide upward through your range. Include head voice or falsetto if you wish. When you reach your highest comfortable note, click "Mark as Highest" to record the ceiling of your vocal range.

View Your Piano Map

Your entire vocal range is highlighted in green on the interactive piano keyboard. Your lowest note shows in blue, highest in orange, and the current singing note lights up in bright orange. Scroll the keyboard to see your full range in context of the piano.

Check Your Voice Type

Frequently Asked Questions

Vocal Range Test FAQ

Everything you need to know about using this free online vocal range test and pitch detector — no registration required for any feature.

What is a vocal range and how is it measured?

A vocal range is the complete span of pitches a singer can produce — from their lowest note to their highest note. It is measured in semitones (the smallest interval in Western music, equivalent to one piano key) or octaves (12 semitones). An average untrained adult voice spans 1.5–2 octaves (18–24 semitones). Trained singers often achieve 2.5–3 octaves or more. Our free online vocal range test measures this span instantly using real-time pitch detection — no registration required, results in under 60 seconds.

How accurate is this free online vocal range test?

This free vocal range tester uses the YIN pitch detection algorithm, which achieves approximately 95–98% accuracy on sustained vowel sounds with a good quality microphone. Accuracy depends on microphone quality, background noise levels, and how clearly and sustainedly you sing each note. For best results: use a quality microphone, sing sustained "ahhh" vowels, ensure a quiet environment, and use a confidence threshold setting of 85%+. The free tool is accurate enough for voice type classification and general range measurement — for clinical voice assessment, a professional voice pathologist evaluation is recommended.

What is the average vocal range for males and females?

Average vocal ranges by voice type: Soprano: C4–C6 (2 octaves) — highest female voice. Mezzo-Soprano: A3–A5 (2 octaves) — middle female voice. Contralto: F3–F5 (2 octaves) — lowest female voice. Tenor: C3–C5 (2 octaves) — highest male voice. Baritone: G2–G4 (2 octaves) — most common male voice. Bass: E2–E4 (2 octaves) — lowest male voice. Untrained adult singers typically span 1.5 octaves comfortably. Use this free online vocal range test to check exactly where your voice sits — no registration required.

Can I test my vocal range without singing — just speaking?

The free vocal range test is optimised for sustained singing, not speech. Speech uses a different and narrower pitch range than singing — typically just 3–6 semitones around your speaking fundamental frequency. For accurate vocal range results, you should sing sustained vowels ("ahhh", "eee") on each note. However, the pitch detector will still identify spoken pitches, so you can use it to check your speaking voice fundamental frequency (the note your voice naturally resonates on when speaking), which typically sits around E3–A3 for men and A3–D4 for women.

Should I include head voice and falsetto in my vocal range test?

This depends on your purpose. Full range: Include all phonation modes — chest voice, mixed voice, head voice, and falsetto. This gives your complete physiological range. Chest voice only: Exclude falsetto and head voice for a more conservative measurement relevant to speaking voice and belting. Classical training: Include both modal and head voice as classical technique requires seamless passaggio crossing. When using this free vocal range test for voice type classification, we recommend testing your full range including head voice, as all seven classical voice types account for the full register. Use the "Mark as Lowest" and "Mark as Highest" buttons to record each extreme as you reach it.

What is the difference between tessitura and vocal range?

Vocal range is the complete span from lowest to highest singable note. Tessitura is the comfortable, sustainable center of that range — where your voice sounds its best and can sing for extended periods without fatigue. A soprano may have a range from G3 to D6, but her tessitura might be C4–G5. Voice type classification in classical music is based primarily on tessitura and timbre, not extreme range limits. Our free vocal range test measures your full range, but for accurate voice type classification, the notes you can sustain comfortably (your tessitura) are more relevant than one-off extremes. No registration needed to use the free tool.

Why does the pitch detector sometimes give wrong notes?

The most common causes of inaccurate pitch detection in this free vocal range test are: 1) Background noise — even moderate ambient sound confuses pitch algorithms; use in a quiet room. 2) Inconsistent phonation — breathy, strained, or whispered notes lack clear fundamental frequencies. Sing with good breath support and clear tone. 3) Microphone quality — very cheap microphones colour the sound and may not accurately reproduce your voice's fundamental frequency. 4) Harmonics detection — occasionally the algorithm latches onto an overtone instead of the fundamental; lower the confidence threshold or increase sensitivity. 5) Confidence threshold too low — raise the minimum confidence setting to 90% to eliminate weak detections.

How many octaves should a singer have?

There is no minimum or ideal number of octaves for singing. Professional singers typically possess 2–2.5 octaves of comfortable range, though some famous singers have 3–4 octaves (Mariah Carey, Freddie Mercury). Beginners often start with 1–1.5 octaves that expands with training. Most pop and rock songs require only 1–1.5 octaves. Opera roles typically span 1.5–2 octaves. More important than raw range is having good tone quality, breath control, and consistency throughout your range. Use this free online vocal range test regularly to track your range as it develops with training — no registration needed, completely free.

Is this free vocal range test safe to use? Does it record my voice?

Completely safe. No audio is recorded, stored, or transmitted when you use this free vocal range test. All pitch detection processing happens entirely within your browser using the Web Audio API — your voice never leaves your device. When you navigate away from the page, all processing stops immediately and no voice data is retained. We do not require registration, do not collect personal data, and do not send any information to external servers. The tool downloads an optional report only if you explicitly click Export — that file goes directly to your device, not to us.

Can I use this free vocal range test on my phone?

Yes — this free online vocal range test works on mobile devices. iOS (Safari 14.5+) and Android (Chrome) both support the Web Audio API required for pitch detection. Mobile microphones are generally lower quality than dedicated microphones, so you may experience slightly less accurate pitch detection on mobile, especially at the extreme ends of your range. For best results on mobile: use Chrome on Android or Safari on iOS, find a quiet environment, hold the phone 15–20cm from your mouth at a slight angle, and increase the sensitivity slightly if notes are not being detected. No registration required, works directly in your mobile browser — free.
