How to find your note

1. Press start and allow the mic

The finder runs entirely in your browser; your voice never leaves your device.

2. Sing or hum one steady note

A closed-lips hum reads cleanest. The big readout is your note; the number is the octave, with middle C as C4.

3. Check the cents meter

Dead center means you are on the note. Left of center is flat, right is sharp.

When a note finder comes in handy

Finding the note a melody starts on, checking whether that high note you can just reach is an F4 or a G4, matching pitch with a recording, tuning by ear, or settling the argument about who was actually on the note. If you sing in a choir or do karaoke, knowing your notes by name makes every conversation about keys and parts easier.

You found your note. Now find your songs.

Knowing you can sing an A3 is a fact. Knowing every song that A3 unlocks is a superpower. HumMatch’s free vocal range test maps your whole range in about 30 seconds with three guided hums, then ranks 40,000+ songs by how singable each one is for your voice, so you always have songs in your vocal range ready to go.

Note finder FAQ

What note am I singing?

Press start, allow the microphone, and sing or hum: the note finder names the note in real time, for example A3 or C#4. It reads your pitch about 45 times per second, so the readout follows your voice as you move between notes.

How do I read a note name like C4 or A3?

The letter is the musical note and the number is the octave, with middle C written as C4. A3 is the A below middle C; C5 is the C an octave above middle C. Higher numbers mean higher pitch.

Do I need to be able to sing to use the note finder?

No. A closed-lips hum works just as well as singing, and often reads more cleanly because there are no words getting in the way of the pitch. If the readout flickers, hum a steady "mmm" instead.

Why does the note jump around while I sing?

Real voices move. Consonants, breaths, and vibrato all wobble the pitch, and the finder is honest about it. Hold a steady vowel or hum and the readout settles. The cents meter tells you how close you sit to the center of the note.

What songs can I sing with my notes?

Once you know your notes, the next step is your range: your lowest and highest comfortable note. Take HumMatch’s free 30-second vocal range test and every one of 40,000+ songs gets ranked by how singable it is for your voice, so you get songs in your vocal range instead of guessing.
