VOCAL RANGE CHECK — FREE, NO SIGN-UP
Vocal range test and karaoke key calculator
Sing your lowest note, then your highest note, and see your range as note names (C4, A4…), solfège and a keyboard. Then pick a song's highest note and the calculator tells you how many semitones to lower (or raise) the key. Audio is analyzed only inside this browser — nothing is recorded or sent.
1. Measure your range
Only notes held steadily for 0.3 s or more, within half a semitone (±50 cents), are counted — a shouted flash or a voice crack doesn't count. Stop right away if your throat hurts.
01Lowest note
Start at speaking pitch on an “ah” and slide down little by little. Stop just before your voice turns into a rasp.
Lowest: —
02Highest note
Slide up little by little from a comfortable pitch. Falsetto counts: go as high as you can hold for 0.3 s without strain. Stop if your throat hurts.
Highest: —
Current note
—
Starting asks for microphone access. Step 1 low end, then step 2 high end.

2. Calculate the best key for a song
Pick the song's highest note (and lowest, if you know it) to get the keys that fit your range. Lowering the key by one moves the whole song down one semitone.
The calculation runs only in this browser. Nothing you select is sent anywhere.

How to use (about 1 minute)
- 01
Start low
Tap “Start range test”, allow the mic, and slide down from speaking pitch. Stop just before your voice breaks up, then tap “Next”.
- 02
Go up to your top
Rise gradually from a comfortable pitch — falsetto counts — up to where you can hold a note for 0.3 s without strain. Tap “See result”.
- 03
Pick the song's top note
In the calculator below, pick the song's highest note (and lowest, if known) to get the recommended key. Log it with your score to compare scores by key.
How many keys should I lower? A step-by-step method
- 01Moving the key by one shifts the whole song by one semitone — the highest and the lowest notes move by the same amount.
- 02First count the gap between the song's highest note and the highest note you can sing comfortably. Example: the song peaks at C5 and you're comfortable up to A4 — that's 3 semitones, so use key −3.
- 03Then check the lowest note. Lower the key too far and the low parts disappear. If neither end has room, prioritize the top note.
- 04If you'd need to drop 7 or more, it's easier to sing an octave down and raise the key to match (−9 = an octave down at key +3). The calculator works within −6…+6 and combines octave-down/up.
- 05Your absolute top note is hard to hit repeatedly. Keep “2 semitones of headroom” on in the calculator to get a comfortable key.
On DAM's precision scoring (Japan)
- ●DAM's precision scoring shows the song's range on a small keyboard at the bottom right for about 5 seconds when the song starts (and while changing key): left end = lowest, right end = highest.
- ●On page 2 of the result screen, keys at the top of the range turn red if you missed high notes; DAM officially suggests lowering the key by the number of red keys (and raising it if the red keys are at the bottom).
Reading note names (C4 = middle C)
Results use scientific pitch notation: C4 is middle C and the number goes up by one each octave. Japanese karaoke guides often use another convention (mid2C, hiA), which splits octaves at A — the table maps the two.
| Japanese karaoke notation | Scientific | Rough guide |
|---|---|---|
| lowA – lowG♯ | A1 – G♯2 | Below a low male speaking voice |
| mid1A – mid1G♯ | A2 – G♯3 | Male speaking voice / low singing |
| mid2A – mid2G♯ | A3 – G♯4 | Male high range / female speaking to middle range (C4 = middle C) |
| hiA – hiG♯ | A4 – G♯5 | Mostly falsetto for men / female high range (A4 = 440 Hz) |
| hihiA – hihiG♯ | A5 – G♯6 | Female falsetto high range |
- ●If two sources disagree on naming, compare in Hz — it's unambiguous.
Typical ranges by voice type (choral / classical convention)
Below the calculator we show the voice type whose typical range is closest to yours, as a rough guide. Voice type really depends on timbre and where your registers change, not just on how high or low you can go.
| Voice type | Scientific | Japanese karaoke notation |
|---|---|---|
| Bass | E2 – E4 | lowE – mid2E |
| Baritone | A2 – A4 | mid1A – hiA |
| Tenor | C3 – C5 | mid1C – hiC |
| Alto | F3 – F5 | mid1F – hiF |
| Mezzo-soprano | A3 – A5 | mid2A – hihiA |
| Soprano | C4 – C6 | mid2C – hihiC |
Ranges are the common guide listed on Wikipedia's “Vocal range”. Untrained singers may have a narrower range — or a wider one including falsetto.
FAQ
- Q. How accurate is this vocal range test?
- A. It counts only notes held steadily for 0.3 s in a quiet place, so it works as a guide to your lowest and highest notes. Background noise and distance from the phone (about 20 cm is good) can change results, and so can the time of day — measure a few times and compare.
- Q. Is my voice recorded or uploaded?
- A. No. Audio is analyzed only inside the browser and is never recorded or sent. Your range is stored in this browser only when you tap “Save”.
- Q. How many keys should I lower in karaoke?
- A. Lower it by the gap between the song's highest note and your comfortable highest note. If the song peaks at C5 and you're comfortable up to A4, use −3. The lowest note moves down too, so check the low parts as well — the calculator checks both at once.
- Q. What if I need to lower it more than the machine allows?
- A. Sing an octave down and raise the key to match: −9 is the same as an octave down at key +3. The calculator includes octave-down and octave-up options.
- Q. I don't know the song's highest note.
- A. Open the pitch checker, sing the highest part of the chorus and read the note name it shows.
- Q. Can I save my range and keys?
- A. Your range can be saved on this device, and the next test shows how it changed. Keys can be logged with scores in KaraScore (free sign-in).

How it's calculated
- ・Published October 24, 2026. Equal temperament with A4 = 440 Hz; C4 = middle C.
- ・Range: only notes held 0.3 s or more within ±50 cents (same calculation and same storage as the pitch checker's range test).
- ・Recommended key: among −6…+6 combined with octave-down/up, the option where the song overflows your range by the fewest semitones; ties go to no octave change, then closest to the original key. If both ends can't fit, reaching the top note wins.
- ・Voice type guide: the type on Wikipedia's “Vocal range” with the largest overlap with your range. It is not a voice classification.
- ・The song's range is what you enter — this site has no per-song range data.
