What note am I singing? Sing or hum one note into your microphone and hold it: this free singing note detector shows the note and octave, the frequency in Hz and whether you are sharp or flat, then locks the note once you have held it for about a second. It also rates how steady you were, plays your note back and keeps a list of every note you sang.

How to Find Out What Note You’re Singing
- Choose your voice: lower (most men), higher (most women) or a child’s voice. This keeps the reading in your range and stops octave jumps.
- Press Start and allow the microphone.
- Sing or hum a comfortable note on “ah” or “mm” and hold it. The big letter shows the note while you sing.
- After about a second of steady singing the note locks: you see “You sang A3”, the exact Hz, how many cents off you were and your steadiness.
- Press Play my note to hear the note you sang, then sing the next one. Every locked note is added to Notes you sang, with your range so far.
Understanding Your Result
| You see | What it means |
|---|---|
| Note and octave (e.g. A3) | The nearest note to what you sang. C4 is middle C; most men sing around C3–C4, most women around C4–C5. |
| ✓ Right on the note | Within ±5 cents: in tune. |
| ▲ sharp: sing a little lower | You are above the note; relax and bring the pitch down slightly. |
| ▼ flat: sing a little higher | You are below the note; add a little more breath support and lift the pitch. |
| Steadiness | How much your pitch wobbled while you held the note. Above 85% is very steady; natural vibrato lowers it a little. |
| Pitch trace | Your pitch over the last 6 seconds: a flat line is a steady note, a wave is vibrato, a slope is a slide. |
What Note Am I Humming?
Humming works just as well as singing, often better, because a hum has a clear, steady pitch and little breath noise. Hum on “mm” with your lips closed and hold the note; the detector locks it the same way. Many people hum lower than they think: if your hum reads around G2–C3 you are using your chest voice, which is normal.
Typical Notes for Each Voice Type
| Voice type | Comfortable range | Typical speaking pitch |
|---|---|---|
| Bass | E2–E4 | about 85–110 Hz |
| Baritone | A2–A4 | about 100–130 Hz |
| Tenor | C3–C5 | about 120–150 Hz |
| Alto | F3–F5 | about 165–200 Hz |
| Mezzo-soprano | A3–A5 | about 180–220 Hz |
| Soprano | C4–C6 | about 200–255 Hz |

Why You Sing Sharp or Flat
Singing slightly flat is usually a sign of tiredness, low breath support or reaching for a note from below; singing sharp often comes from tension, pushing volume or nerves. Low notes tend to go flat and high notes sharp. The guide on why singers go sharp or flat covers the causes and fixes, and these warm-up exercises to stay on pitch help before practice.
Practise Hitting the Right Note
- Match and check: press Play my note, sing it again and see if the lock says “right on the note”.
- Slide into the centre: start a little low and slide up until the guide says you are in tune, then hold.
- Hold for five seconds: watch the trace stay flat and your steadiness rise.
- Step by step: sing up a scale one note at a time and look at the list; each step should be one or two semitones.
- Record your progress: copy your result and compare it next week.
Frequently Asked Questions
How do I know what note I’m singing?
Hold one note for about a second: the detector locks it and shows the note name and octave, for example “You sang G3”, with how many cents sharp or flat you were.
Why does the note jump an octave?
Breathy or very quiet singing can confuse any detector. Choose your voice setting, sing a little louder and steadier, and hold the note.
Can it tell what note I’m hitting in a song?
Yes, note by note: sing each note of the song slowly and it builds the list of notes you sang.
Which note should I start with?
Start with a note you can speak on comfortably, then slide up and down from there. For most men that is around C3 to G3; for most women around G3 to D4. Warm up gently before trying very high or very low notes.
Does it work with a guitar, piano or other instrument?
It is tuned for voices. For instruments, use the note finder, which also shows the note on a staff and handles trumpet, clarinet and saxophone transposition.
Why does the steadiness go down when I use vibrato?
Vibrato moves the pitch up and down a little several times a second, so the reading measures it as movement. A centred vibrato still locks the right note; for a steadiness check, sing the note straight first.
