Tune cello strings to C2-G2-D3-A3 with microphone pitch detection designed for the instrument's low register and perfect-fifth string layout.
Standard cello tuning is C2-G2-D3-A3 from the lowest string to the highest. Like violin and viola, adjacent strings are tuned in perfect fifths, but the complete register is lower.
The target setup on this page is C2 - G2 - D3 - A3.
Pitch analysis runs continuously in the browser and displays the nearest target, frequency, and cents difference.
The tuner shows whether the current note needs to move up, move down, or is within the in-tune range.
Select a visible target to hear a clean reference pitch when you want to compare the instrument by ear.
Microphone samples are analyzed locally and are not uploaded as an audio recording.
Tune in a quiet room and play only one clear note or open string at a time.
Start with C2 - G2 - D3 - A3. Available alternatives include Standard cello CGDA with Chromatic mode available for scordatura and ensemble-specific references.
Allow microphone access, keep the instrument close enough for a clean signal, and avoid other sustained sounds.
Play one open string and let it sustain while the tuner selects or follows its target.
Move gradually toward the center, then repeat every target because changing one string can slightly affect the others.
Use the dedicated preset when the target notes and physical string order matter more than a general chromatic reading.
Bow or pluck one string at a time and mute neighboring strings so their sympathetic resonance does not move the reading.
Use fine tuners for small changes and pegs only when the pitch is too far from the target.
Allow the C string to sustain after its attack so the detector can settle on the fundamental instead of an overtone.
Match A4 to the reference used by the ensemble before tuning A, D, G, and C in sequence.
Both use the same pitch detector, but they organize targets differently.
| Cello Tuner preset | Chromatic mode | |
|---|---|---|
| Targets | C2 - G2 - D3 - A3 | All twelve semitones |
| Visual layout | Instrument-specific pegs and strings | Detected note and cents |
| Best for | Cello Tuner | Custom tunings and other pitched instruments |
| Tuning choice | Standard cello CGDA with Chromatic mode available for scordatura and ensemble-specific references | No instrument tuning required |
A dedicated preset is easier when you want the correct string order. Chromatic mode is more flexible when you already know the target note.
Yes. It runs in a supported browser without requiring an account or installing a tuning app.
The default targets are C2 - G2 - D3 - A3.
Yes. Allow microphone permission, keep the device near the instrument, and play in a quiet place for a more stable reading.
One semitone contains 100 cents. A negative reading is flat, a positive reading is sharp, and a value close to zero is in tune.
Other strings, room noise, overtones, and a hard attack can compete with the fundamental. Mute unused strings and read the note after it settles.
No. Live microphone analysis stays in the browser and the tuner does not create or upload an audio recording.
