Slide down on “ah” to the lowest note you can still hold, and keep it steady for about 2 seconds. The lowest note test shows the note, its Hz and the voice types that bottom out nearby. Free, no sign-up, in your browser.
How it works
Low notes are quiet, so get a little closer to the mic than usual and pick the calmest room you can.
Step 1
Press Start test and allow the microphone. Keep your phone or laptop about a forearm's length away, relax your jaw and shoulders, and hum a few easy notes in the middle of your voice first.
Step 2
Sing “ah” or “uh” and slide down slowly to the lowest note you can still hold with a clear tone. Keep it steady for about 2 seconds until the ring fills. Try a few times; the test keeps your lowest steady note.
Step 3
You get your lowest comfortable note with its frequency, any brief dip below it, the voice types whose typical bottom is nearest, how far above or below each one you sit, and singers with a similar low note.
Quick reference
The bottom of each voice type’s usual classical range. Your lowest note is set mostly by anatomy, so it moves much less with training than your top.
| Voice type | Typical lowest note | Frequency |
|---|---|---|
| Basso profundo | C2 or lower | 65 Hz and below |
| Bass | E2 | 82 Hz |
| Baritone | A2 | 110 Hz |
| Tenor | C3 | 131 Hz |
| Alto (contralto) | F3 (deep contraltos to D3) | 175 Hz |
| Mezzo-soprano | A3 | 220 Hz |
| Soprano | C4 (middle C) | 262 Hz |
Commonly cited classical ranges, the same ones your result is compared with. Countertenors are left out: they sing mostly in head voice, and their chest-voice bottom is usually that of a baritone or tenor. Notes use scientific pitch notation, where C4 is middle C.
Highlights
Low notes are the hardest to measure: they're soft, breathy and easy to confuse with rumble. Here's how this low note test handles them.
A note counts only after you hold it steadily for about 2 seconds. Growls, creaks and vocal fry rarely carry a clear, stable pitch, so they don't drag your result down to a note you can't really sing. A brief dip lower is shown separately.
The test switches off your browser's noise suppression and automatic gain control, features that can treat a quiet, low hum as background noise and filter it out. That keeps soft bottom notes audible to the pitch detector, down to about B1 (62 Hz).
Your lowest note is checked against the typical bottom of all seven voice types, with the gap in semitones, plus singers with a similar lowest note. Filter the comparison to male or female voices if you prefer, then share or save the result.
Everything runs in your browser, nothing is uploaded and there's no account to create. No microphone, or a noisy room? Play notes on the built-in keyboard, hum along and pick the lowest one you can hold comfortably.
Your lowest note is the most physical part of your range. Longer, thicker vocal folds vibrate more slowly, which is why adult men's voices sit about an octave below women's and why bass and baritone voices are largely a matter of build. Training can make low notes clearer and more resonant, but it usually adds far less at the bottom than at the top. That makes your lowest note a useful clue to voice type, often more telling than your highest.
Your bottom note also changes through the day. Many singers find a note or two extra first thing in the morning, when the vocal folds are slightly swollen and heavier, and lose them once the voice warms up. Hormones matter too: boys' voices drop during puberty, and many women's voices get a little lower after menopause. So test a few times, at different times of day, and use the note you can find reliably.
Don't press down. Pushing your chin into your chest or forcing your larynx low makes the sound pressed and growly, and it rarely adds a usable note. Instead, keep your neck long and your jaw loose, lower the volume, and let the note get softer and a little breathier as you descend. A relaxed “uh” or “oh” usually goes lower than a bright “ee”.
Hum first. Humming on “mm” down a five-note scale lets you feel the bottom without strain, and starting each low note slightly louder than a whisper gives the mic something to read.

Stop if your throat feels scratchy, and see a doctor if hoarseness lasts more than two to three weeks.
Curious how your speaking voice compares? The deep voice test measures the average Hz of your talking voice, while the bass vocal range guide explains what a true bass can sing and how to tell it from a baritone. For the other end of your voice, the highest note test works the same way, sliding up instead of down.

Use cases
Low notes matter more than most people think, from choir parts to picking a karaoke key.
Check whether you can really carry a bass part, or whether baritone fits you better, before a choir audition.
Make sure a song's verse doesn't dip below your floor, or work out how many semitones to raise the key.
Find out how far down your voice actually goes, and compare your note with well-known low singers.
Record a student's reliable bottom note in the first lesson and recheck it as their voice matures.
