🎵 Pitch Detector
See your pitch in real-time as you sing or play. Perfect for vocal training and pitch accuracy practice.
Need a Reference Note?
Ear Training
Can't find the pitch? Play a reference note first, listen carefully, then try to match it.
Working on Rhythm?
Tempo Control
Pitch is only half the battle. Practice your scales and songs with a steady beat.
🎤 Singing Practice Path
Use this page as the feedback step in a short loop: hear a reference on the Tone Generator, sing here, then lock rhythm on the Metronome. If you are preparing a cover, pair with the Song Key Finder after the Vocal Range Test so you practice in a key that fits your voice.
10-Minute Session: Reference → Sing → Steady Time
- 1On the Tone Generator, play a comfortable note (often C4 or a note from your Vocal Range Test) at low volume with a sine wave. Listen for two seconds.
- 2Return here, start the microphone, and sing the same pitch on a steady “Ah” for 3–5 seconds. Aim for the green zone (within about ±10 cents).
- 3Repeat with a second note a major third or fifth above—play the reference, then sing without scooping.
- 4Finish with the Online Metronome at 72–80 BPM: sing a five-note scale or one phrase of your song, one syllable per beat.
Three routines you can repeat daily
Calibration Match
Tool settings: Tone Generator · sine · 30–40% volume
Play Middle C (C4) or your chosen root. Stop the tone, then sing and hold. If you are flat, add breath support; if sharp, relax the jaw and tongue.
Goal: Hold the needle in the green zone for 3 seconds on one note.
Stability Hold
Pick a comfortable note in your range. Sing straight tone (no vibrato) for 5 seconds per attempt. Rest 10 seconds between tries.
Goal: Keep deviation within ±10 cents without wavering.
Scale + Tempo
Tool settings: Metronome 72 BPM · optional Tone on first note only
Sing Do–Re–Mi–Fa–Sol up and down on “La.” Use the generator only on Do and Sol to check endpoints; inner notes are from memory.
Goal: Land each scale step in the center—not sliding up into pitch.

📖 How to Use This Tool
Start the Detector
Click the microphone button to allow access. We process audio directly in your browser, so your voice is never recorded or sent to a server.
Sing a Steady Note
Hold a comfortable note for a few seconds. Watch the needle move to see your pitch stability.
Check Your Tuning
- Green (Center): In tune (±10 cents).
- Right: Sharp (too high). Relax throat.
- Left: Flat (too low). Support breath.
Practice Scales
Once you can hold a single note, try singing a simple scale (Do-Re-Mi) and see if you can hit each step accurately.
🎯 Understanding Your Results
Note Name (e.g., C4, A3)
This shows the musical note you're singing. The letter (C, D, E, F, G, A, B) represents the pitch class, and the number represents the octave.
Example: C4 is "Middle C" on a piano, the most common reference note. A4 (440 Hz) is the standard tuning pitch used by orchestras worldwide.
Frequency (Hz - Hertz)
This is the number of sound wave vibrations per second. Higher numbers = higher pitch.
Common frequencies:
- Male voices: typically 85-180 Hz (low notes) to 330-660 Hz (high notes)
- Female voices: typically 165-255 Hz (low notes) to 660-1,100 Hz (high notes)
- Middle C (C4): 261.63 Hz
- Concert A (A4): 440 Hz
Cents (Pitch Accuracy)
A "cent" is a unit of musical pitch. There are 100 cents between any two adjacent notes. The indicator shows how close you are to the target note.
In Tune (±10 cents)
Excellent! Your pitch is accurate enough for most musical contexts.
Flat (negative cents)
Your pitch is slightly lower than the target note. Try singing a bit higher.
Sharp (positive cents)
Your pitch is slightly higher than the target note. Try singing a bit lower.

About This Pitch Detector
SingMeter's Pitch Detector is a real-time vocal analysis tool designed to help singers train their ear and improve their pitch accuracy. By visualizing the exact frequency of your voice, you can see instantly whether you are singing in tune, sharp (too high), or flat (too low).
Unlike a simple guitar tuner, this tool is optimized for the human voice. It detects the fundamental frequency of your singing and maps it to the closest musical note, showing you the deviation in "cents."
Understanding Pitch & Cents
In music, the distance between two semitones (like C and C#) is divided into 100 smaller units called cents.
- 0 cents: Perfect pitch accuracy.
- ±10 cents: Generally considered "in tune" to the human ear.
- ±25 cents: Noticeably out of tune for trained listeners.
- ±50 cents: You are halfway to the next note (quarter tone).
Most professional singers naturally fluctuate within ±10-15 cents due to vibrato and expression. The goal isn't to be robotic, but to center your pitch so it feels stable.
Vocal Practice Routines
1. The "Siren" Exercise
Slide your voice from your lowest comfortable note to your highest and back down, like a siren. Watch the pitch detector track your movement. Aim for a smooth line without breaks or jumps.
2. Long Tones
Pick a comfortable note (like C4 or G3) and hold it for as long as you can on a single breath. Try to keep the needle in the green zone the entire time.
3. Interval Jumps
Sing a root note, then jump up a 5th (e.g., C to G) and hold it. Check if you landed directly on the note or if you had to "scoop" up to it.
4. Steps vs. Skips
Practice moving by half-steps (chromatic scale) versus whole steps. This trains your fine motor control.
Limitations & Disclaimer
While this tool is highly accurate, it relies on your device's microphone. Background noise, poor microphone quality, or echo can affect results. Also, remember that this is an educational tool, not a medical device. If you feel pain or strain while singing, stop immediately and consult a professional.
