Chromatic Tuner & Pitch Detector
The chromatic tuner shows the nearest note to any sound: your voice, a whistle, a piano, a flute or a string. It shows the note name and octave, the exact frequency in hertz and how many cents sharp or flat you are, with a pitch trace so you can see how steady your note is.
Sound is analysed on your device; nothing is recorded or uploaded.

About the Chromatic Tuner & Pitch Detector
The chromatic tuner shows the nearest note to any sound: your voice, a whistle, a piano, a flute or a string. It shows the note name and octave, the exact frequency in hertz and how many cents sharp or flat you are, with a pitch trace so you can see how steady your note is.
How to use it
- 1 Press Start tuner and allow the microphone.
- 2 Pick your tuning, or keep Standard (E A D G B E).
- 3 Pluck one open string and let it ring: the tuner shows the string and a needle.
- 4 Tighten the string if it says tune up, loosen it if it says tune down, until the needle sits in the green and the string gets a tick.
Frequently asked questions
What is a chromatic tuner?
A tuner that recognises all 12 notes of the scale instead of only an instrument’s open strings. Use it for any instrument, alternate tunings, or to check whether you are singing in tune.
Can I use it to find the pitch of my voice?
Yes. Sing a steady “ah” close to the microphone; the note, frequency and cents offset appear, and the trace shows whether you drift. Most men speak around 85–155 Hz and women around 165–255 Hz.
What does cents mean?
A cent is a hundredth of a semitone. ±5 cents is close enough for most listeners; beyond about ±10 cents most people hear that a note is out of tune.
Is my audio recorded or uploaded?
No. The tuner analyses the sound from your microphone in your browser, a few times a second, and throws it away. Nothing is recorded, saved or sent to a server.
Why does the tuner jump between notes?
Usually because more than one string is ringing, the room is noisy, or the note has faded. Mute the other strings with your fretting hand, pluck firmly, and read the needle while the note is still strong. Moving closer to the microphone helps on laptops.
