Why Use a Pitch Detector Instead of Guessing by Ear
Your ear adapts to what it hears, so a note that drifts a little flat can still feel right while you sing it. Recording yourself and checking every phrase against a piano takes minutes per line. A pitch detector, sometimes called a pitch recognizer, listens with you in real time and names the exact note, so you fix it in the moment instead of after the take.
- Singing slightly flat or sharp is hard to hear from the inside, especially on long notes.
- Working out what notes are these in a riff means replaying it again and again on an instrument.
- Most note identifier apps want an install, an account or a subscription before they listen.
- You know the songs you love, but not which notes you can reach, so picking a key is guesswork.
- Checking one note at a time against a keyboard eats the practice time you actually have.
What the Online Pitch Detector Shows You
Every reading answers two questions at once: which note is this, and how close am I to the center of it?
Note Name and Octave
The nearest note with its octave, such as A4 or C#3, in sharps or flats, so you always know where you are on the keyboard.
Cents Sharp or Flat
A needle shows how far you sit from the center of the note, from 50 cents flat to 50 cents sharp, and lights up when you are in tune.
Frequency in Hz
The exact frequency of your voice or instrument, handy for checking a reference pitch or a test tone.
Live Pitch Graph
Your pitch draws a line across a piano lane, so slides, vibrato and notes that sag at the end are easy to spot.
Your Vocal Range
Sing your lowest and highest comfortable notes and see your range on a keyboard, with an estimate of the voice type it sits closest to.
Private and Free
The sound is analyzed in your browser and never recorded or uploaded. Use the note detector online as often as you like, with no account.
How to Use the Pitch Detector in Three Steps
From microphone to note name in a few seconds, on a laptop, a tablet or a phone.
- 1
Allow the microphone
Click Start and allow microphone access when your browser asks. A quiet room and a mic close to the sound give the cleanest reading.
- 2
Sing or play one note
Hold a single note for a moment. Like any singing note detector, it follows one voice or one instrument at a time, so turn off backing tracks and play notes rather than chords.
- 3
Read the note and adjust
The note name, octave, cents needle and frequency update as you go. Watch the graph to see whether you drift, then move toward the center until the needle settles.
Features of the EzTranscriber Note Finder
A pitch tester, a note identifier and a vocal range test on one free page.
A Note Finder for Voice, Piano, Guitar and More
Play a piano key, pluck a string or hum a melody and the music note finder names it straight away. Note recognition happens on your device in real time. It works as a piano note identifier, a music note detector for guitar, violin, flute or brass, and a note identifier by sound for anything that plays one pitch at a time. Not sure what note is that in a song you are learning? Use it as a song note finder: play it back on your instrument or hum it and read the answer. Because it also shows the frequency, the online note detector doubles as an online frequency detector for test tones and reference pitches.
Find a NoteSinging Pitch Detector With a Live Pitch Graph
Singers need more than one number. The graph draws your pitch over time on top of a piano lane, so you see the slide into a note, the width of your vibrato and the phrase that sags at the end. As a singing pitch detector it shows in cents whether you are sharp or flat, and as a voice pitch detector it keeps following you through a whole line, not just a single note. Freeze the graph to study a phrase, clear it and try again. Have a recording instead of a live voice? Analyze a Recording draws the same pitch curve from an audio file. Think of it as a pitch meter for your practice room, or a voice pitch analyzer online that never gets tired of listening.
Practice SingingPitch Tester With Target Notes
Pick a target note, play its reference tone, then sing it back. The pitch tester tells you how many cents you are off and whether to go higher or lower, then celebrates when you hold the note for two seconds, which turns ear training into a quick game. Voice teachers use it as a pitch checker online for warmups, and choir singers use it to find their starting note without a piano in the room. It is the same note pitch detector underneath, a simple music pitch finder tool that gives every attempt an honest reading in cents.
Try a Target NoteVocal Range Test With Your Voice Type
The range test walks you through it: sing your lowest comfortable note, then your highest, holding each for a moment, and see your range on a keyboard, for example A2 to F4, with an estimate of the closest voice type from bass to soprano. Save the result as an image or copy it, or enter your notes by hand if you have no microphone. Use it to choose songs in keys that suit you, then move any track into your range with the pitch changer. Take the test again after a few weeks of practice and compare.

Middle C is C4. Every octave doubles the frequency: A3 is 220 Hz, A4 is 440 Hz and A5 is 880 Hz.
A4
440.00 Hz
In tuneMiddle C is C4 at about 261.63 Hz, and A4 is the 440 Hz reference most instruments tune to. Every octave doubles the frequency, and each of the 12 semitones in between is 100 cents. Move the detune slider and watch the needle: within a few cents, most listeners hear a note as perfectly in tune.
Vocal Range Test Chart: Voice Types and Ranges
Typical ranges used by choirs and voice teachers. Your result will sit closest to one of these.
| Vocal Range Test Chart: Voice Types and Ranges | Typical range | Where it sits |
|---|---|---|
| Bass | E2 to E4 | The lowest voice, with deep, rich bottom notes. |
| Baritone | G2 to G4 | The most common male range, between bass and tenor. |
| Tenor | C3 to C5 | The high male voice, bright and ringing at the top. |
| Alto | F3 to F5 | The lowest female voice, warm in the middle. |
| Mezzo-soprano | A3 to A5 | Between alto and soprano, common among pop singers. |
| Soprano | C4 to C6 | The highest voice type, light and clear above the staff. |

Who Uses an Online Pitch Detector
Anyone who wants to know which note they are making, and how close it is.
Guitarists and Bassists
Check single notes, harmonics and bends, or switch to the online tuner for string by string tuning.
Piano and Keyboard Players
Use it as a piano note finder for an old upright. Play each key into the note finder: piano strings drift over time and the cents needle shows which ones are off.
Teachers and Choirs
Use it as a note checker: music students match a given note and the needle shows how close they are. Ear training without a piano in the room.
Songwriters
Hum an idea and identify notes before it fades, then turn a full recording into notes with audio to MIDI.
Producers
Check the pitch of a sample, a vocal chop or a bass hit, then confirm the song key with the BPM and key finder.
What Singers and Musicians Say About the Note Finder
I always worried about going flat on long notes in choir. The pitch graph showed me exactly where I sag, and two weeks later my long notes stay on the center line.
Hannah Brooks
Choir Alto
The range test suggested baritone rather than tenor, which explains why every song I picked felt too high. Now I transpose before I start.
Jamal Carter
Hobby Singer
My students play a note on the violin and see the cents straight away. As a music note identifier for intonation practice it saves me so much explaining.
Elena Petrova
Violin Teacher
Humming a melody into the detector and writing down each note is now the first step of every song I write. No app, just a browser tab.

Songwriter
Pitch Detector FAQs
Quick answers about finding the pitch of your voice or instrument.
How do I find the pitch of my voice online?
Open the tool at the top of this page, click Start and allow the microphone, then sing one steady note. The note, octave, cents and frequency appear live, and the graph shows how your pitch moves.
How do I work out what notes are these in a melody?
Sing or play the melody slowly, one note at a time, and read each one from the song note detector. To find the notes of a song from a full recording with many notes at once, convert it with audio to MIDI and read them on the piano roll.
Is it free?
Yes. It is free, with no sign-in and no limit on how long you use it, because the analysis runs in your browser.
Is my microphone audio recorded or uploaded?
No. The sound is analyzed on your device as it arrives and is never stored or sent to a server. The microphone turns off when you stop or leave the page.
What do Hz and cents mean?
Hz is the frequency of the sound, how many times per second it vibrates. Cents measure small distances between notes: one semitone is 100 cents, so a reading of +20 means you are a little sharp of the note shown.
Why does the detected note jump or disappear?
Background noise, chords, a backing track or a very breathy sound make it hard to find one clear pitch. Sing or play a single steady note close to the microphone in a quiet room. Very short notes may not register, because the note detector needs a moment of sound.
Can I use it as a piano note identifier or for guitar?
Yes. It works for any instrument that plays one note at a time: piano keys, guitar and bass strings, violin, flute or brass, and teachers use it as a quick music note checker. For string by string tuning with presets, use the online tuner.
How does the vocal range test work?
Start the range test, sing your lowest comfortable note and hold it, then do the same with your highest. The result shows both notes on a keyboard, the number of semitones between them and an estimate of the voice type closest to your range. It is a range check, not a judgment of your voice.
How do I compare my range with a singer I like?
Look up the lowest and highest notes the singer is known for, the Taylor Swift vocal range for example, and find both on the keyboard in your result. If a song sits above or below your range, move it into your range with the pitch changer.
What is the pitch of a song?
A song has a different pitch for every note, so it has no single pitch. People usually mean its key, which a key finder reads from the whole track; try the BPM and key finder. To check one note of the melody, sing or play it into the pitch detector, which works as a song note identifier one note at a time.
Can I find the notes of an MP3 or a voice memo?
Yes. Switch to Analyze a Recording and drop in an MP3, WAV, M4A, FLAC, OGG or AAC file of up to 100 MB; the first five minutes are analyzed. The pitch detector for MP3 files draws the pitch curve of the melody, so it works as a note finder from MP3 recordings and other audio. It reads one melody line best, such as a voice or a solo instrument, and exports the pitch data as CSV. For editable MIDI notes, use audio to MIDI.
What does A4 calibration do?
Most music tunes A4 to 440 Hz, but some orchestras use 442 Hz and some players prefer 432 Hz. Set the reference anywhere from 430 to 450 Hz to match your band or recording, and every note and cents reading follows it.
Does it work on a phone?
It runs in modern browsers on laptops, tablets and phones. Allow microphone access when the browser asks, and keep the phone close to your voice or instrument for a steady reading. It also makes a handy online mic test: pitch detector readings appear as soon as the mic hears you.
